A bit of thinking out loud here but I just found the difference, and maybe the answer to my own question:

a) Pimax's percentage is based on a percentage of the resolution figure (eg percentage of horizontal or vertical only). Eg 75% of 4312 is 3232 wide.

b) Steam's percentage is based on a percentage of the calculated render total pixels and does not care about width/height percentage.

 

Yes you are right here.

 

When talking about applying supersampling there are two ways to introduce it:

 

1.) Based on TOTAL Pixels. This way is the one used by the % used in SteamVR. I think is it better since 200% means double than 100% (so double GPU power needed)

2.) Based on multiplier of each axis. So if you apply 1.2 factor to each axis you increase 1.2X1.2 the original resolution. So the final % in terms of TOTAL Pixel is 1.2 squared. I think this is less intuitive.

 

I think with the two tables shown above (Balanced, Maximun) it is clearer.

Not fine enough control and editing config files is tedious when they get overwritten.

I ahve never touched config files in IL-2 (just my choice) and restart IL-2 and SteamVR everytime I introduce a change either in SteamVR or in IL-2. Sometimes I even just restart computer (you never know).

It would not suprise me if they natively built in super sampling.

 

I was talking about the final rendered resolution, not the resolution of the physical panel which is almost exactly the same.

Every device (also Aero) introduce what you call a "built in" supersampling ratio when SteamVR is set to 100%. This is the "Absolute SS ratio" I was referring in the table above.

Hey I am glad the Crystal exists and while it appears to have many issues there are some that are quite happy, and this is a great thing for PC-VR. I tip my hat to Pimax for continuing to still offer native PC-VR headsets for the enthusiast. I myself do not like the company and how they do their business, but I don't take away what they are doing for VR and I hope they continue.  As long as the buyer understands their modus operandi going in (I really wish they would change this) I am sure they eventually will have a satisfying experince.

Yes, I also think like you here. It is really great they exist to produce headsets that fit simmer uses cases.

I would not mine to buy again from them if they produce a less bulky headset with less inertia (momentum) and larger FOV.

Good to know. You can report this to the fpsVR developper, he normally investigate things.

[TAIPAN_]

Thanks for confirming all that, I think I've got VR tweaking fatigue now

Actually just a bit sick with a cold, but trying out a few other VR titles to enjoy the headset as well.

 

MSFS is a real dog in terms of FPS, there seems to be nothing you can do to make it keep up with IL2 or DCS's performance except suck it up and accept that civ flying doesn't need to be as smooth and deal with 40-60fps depending on environment.

For the config files I'm referring to the Pimax software, we can change things in the config ".json" files that the software uses to set resolution etc and get more granular control. The downside is when you go back into the software and change something there it can overwrite your changes. So far the only thing that I have to change in the config is the local dimming because extreme is too much, and highlight is too little. Resolution I change in Steam or OpenXR depending on title

New software is released @Charlo-VR

 

Both PimaxPlay and firmware. 

 

To try DFR, turn on Foveated Rendering and Eye tracking in Pimax client, and do the eye tracking calibration.

Just assumption based on the spreadsheet Charlo linked here 

I haven't tested in IL-2 for the performance differences but that tester is usually right. 

 

This is VRS based DFR though, via the Pimax driver (OpenVR mode). 

 

QuadViews is something different and kind of special, and only works in OpenXR mode. So far I only know two games that implement it - DCS and Pavlov VR.

I gave the new DFR and eye tracking a shot and it does indeed improve performance by something like 10 fps. I also tried out the 120 Hz mode and that was also a little bit nicer, though did introduce more fluctuations in my FPS, to the tune of dropping into the 70s at times but averaging around 93 fps.

 

However, I ended up turning both of those off because each would cause IL-2 to crash - not always, but five times within 90 minutes of testing, whether SP or MP. IL-2 rarely crashed before this update, and did not crash after I turned off those features.

 

No big deal to me - I didn't really notice the visual difference with or without DFR and/or 120Hz mode, perhaps because I have a 4090 and 13700k, so was enjoying generally close to 90 fps most of the time before trying those new features.  I'm quite pleased with the Crystal at 90Hz and without DFR, so long as I use an Apache strap so that it sits on my head more or less like a hat.

 

I also found it more comfortable after adding 100 grams of counterweight just above the rear strap adjuster knob. It turns out 10 American nickels weighs 50 grams, so a bit of electrical tape and $1 worth of nickels now helps keep any weight off my nose and cheeks.

 

Oh - and as others have posted in this Reddit thread, I am not the only way experiencing a bit of visual vibration because I use base shakers (in my case, both a Buttkicker and a Next Level Racing HF8 haptic seat pad, both with SimShaker Wings). 
 

The vibrating seems a little less noticeable since this latest Pimax update, but perhaps I'm just getting used to it. While I prefer that slight vibration be fixed in a future update, for now it just seems to feel like my vision is slightly affected by sitting in a very powerful, vibrating warbird.

[56RAF_Roke]

Thanks for the update @Charlo-VR. I've been contemplating buying the Crystal but have been waiting to see how much DFR helps the experience.

 

Seems like the performance gain would still be worth it - if they can sort the crashes. I wonder if other Crystal users have the same experience in Il2?

 

 

 

[TAIPAN_]

Thanks that's interesting about the crashes,For my crashes they happened even when I turned DFR off in PimaxPlay and restarted SteamVR, so I thought I ruled out DFR as causing them. 

 

Crashes were possibly due to the 120hz? Though I don't see the reason a refresh rate would be noticeable to IL2.

 

In my very short test run, I stopped crashes happening by making sure NOT to have fpsVR running when I clicked fly. The crashes would happen near the very start of each flight. Without fpsVR it seemed ok.

 

Were you running fpsVR @Charlo-VR ?

 

That vibration issue is a strange one, the reddit post seems to say it started with the firmware update for some.. which means it would be software not physical lense vibration. Weird.

 

 

@56RAF_Roke if you play DCS or Pavlov VR, the DFR is something I'd never want to go without because it uses a special implementation called QuadViews. It's just crazy how good it looks and how well it runs (200% supersampling in my gaze area, running at 80-90fps). IL2 not conclusive yet, I wish I had time to test.

 

Also what type of video card do you have? The native DFR is VRS which for directx11 games only works on Nvidia cards. AMD cards VRS requires games to run in Directx12 to activate it, ie not many games.

 

The spreadsheet Charlo linked before has some info on games tested, also today a pretty technical video but a few benchmarks here if you're into that:

I tried DFR without running fpsVR and didn’t have any crashes, but frankly am no longer convinced either DFR or FFR are working with IL-2. I don’t see any indication of it working, nor much change in FPS, but perhaps the benefits are just too small to be noticeable with IL-2 and a 4090 and 13700k.

 

I’ll watch to see if other, smarter people have noticeable results in IL-2.

 

I had noticed the vibration issue before the latest update, and if anything it has slightly improved with this update, or I am getting used to it.

Thank you for keep us informed about how this work.

 

In a previous post above you said to got about +10fps when activating DFR, and here you say the benefit is too small?  ?

 

First question, what is the resolution mode you used in the Pimax software (0.75, 1.0?) and what was the SteamVR SS% you used in your DFR tests?

 

As you know, if you run in 90Hz mode and you normally get 90fps you will most likely don´t see any difference.

 

I assume you used the 120Hz mode to see if DFR helps your GPU to reach 120fps, but then the CPU could became the bottleneck (DFR only helps to GPU not to CPU)

 

I think the best way to test the DFR is to run a low CPU scenario with a high %SS. For example, you could use the SYN_VAnder bench with Balanced PRe-set and most of the IL-2 settings to the low value (to minimize load to CPU) and then use the 1.0 Pimax mode with 150% SS SteamVR.( or a value that will give you around 50-60 fps being GPU the bottleneck without DFR). And then run again but with DFR being sure the CPU is not the bottleneck (looking CPU frametimes).

 

You don´t need fpsVR, you can use GPU and CPU Frametimes window of SteamVR.

[56RAF_Roke]

@TAIPAN_, sadly I only have time for Il2 these days. The DCS implementation of this sounds mouth-watering though. 

 

I have a 4090 with a 5800X3D, and am pretty happy with my G2 at present, with pretty high settings achieving 90fps. 

 

My hope is that DFR would enable me to enjoy the greater resolution and clarity of the Crystal without having to turn any of the in-game settings I'm currently using  down. 

 

It sounds like at present that might not be possible... Although the experience will still be an improvement overall. That's why I appreciate the contributions on the thread and am watching it with interest.

PimaxClient at 1.0 render, SteamSS set to 80% in the General and Video tabs of SteamVR, indicating a resolution per eye of 3856 x 4560. However, SteamVR further set to 87% in my "Per-Application Video Settings" for IL-2, so 3596 x 4256 per eye.  When using 90 Hz mode and no DFR, that allows me to keep my FPS in the upper 80s or at 90 in both MP and in a Quick Mission with 8 fighters and 8 two-engine attackers over Kuban. My GPU frametimes stay in the low 8 ms, CPU low 7 ms, and this has been the smoothest experience amongst my tests.

 

Also in a Quick Mission with 8 fighters and 8 two-engine attackers over Kuban:

 

120 Hz, DFR Off: avg. 90 FPS with some FPS at 114, 6 and 7 ms both CPUand GPU, but introduces some stuttering

120 Hz, DFR on Maximum: average 86 FPS, with planes occasionally becoming briefly transparent. No noticeable visual effects indicating DFR is working.

120 Hz, DFR on Balanced: average 86 fps, some stuttering, CPU frametimes above 9ms, GPU above 8 ms. No noticeable visual effects indicating DFR is working.

 

I am using pimax-openxr as my OpenXR Runtime. Oh, and using fpsVR did not cause any crashes, either in SP or MP.

 

Someone else will have to add their own DFR testing for now as I will be away from my gaming rig for the next two weeks ?

Thank you for this test.

When you run at 90Hz your reprojection limit is 11.1 ms (1000/90).

When you run at 120Hz your reprojection limit is 8.3 ms (1000/120).

 

So it seems you don´t go beyond 86 because you are CPU limited, although with 9ms CPU frametimes you should reach 111fps (1000/9).

 

Perhaps the best to see if there is an improvement is to do this two tests:

 

Test1: DFR off, 90Hz, Balanced preset, Pimax Client at 1.0, SteamVR at 120% or 130%. You should then have fps around 50-60fps being your GPU the only bottleneck

Test2: DFR on, 90Hz, Balanced preset, Pimax Client at 1.0, SteamVR at 120% or 130%. Then we should see the gain

Why run 120 Hz? Does it not look ok at 90Hz? Seems should really help performance.

[Charlo-VRde]

Yes, it looks better and is smoother at 90 Hz, I was only testing at 120 Hz to see if DFR may be working and to see what 120 Hz may look like.

 

At 90 Hz and no DFR, compared to my Reverb G2 I have survived more successfully in MP because of the longer spotting ability and increased vertical FOV that allows me to track better during combat ?

[mbucchia]

So I'm finally taking some time to try Pimax DFR out with IL2.

 

Important Note: a few months back when the first beta of Pimax eye tracking came out, I built myself a special version of their tool (their support for FFR/DFR is called "libmagic", you can see the files in the Pimax folder). That special version can work on non-Pimax headsets in both FFR and DFR mode (all I did is write a little DLL to pretend to be a Crystal).

 

While doing this, I found a hidden mode (not advertised in Pimax Play) that can be used for debugging. It corresponds to setting Pimax's variable `foveated_rendering_level` to value 3 (other values are 0-2 corresponding to the options in Pimax Play).

 

In this mode, the center area (normally rendered at full resolution) is set to cull (don't draw any pixels). This makes it easy to see if things work.

 

So far what I found out is that yes, Pimax foveated rendering (libmagic) is able to hook to IL-2 and yes it is performing _some_ foveated rendering. I don't know yet if it's actually getting all the render passes (one thing that nullifies foveated rendering is app only able to hook into the final pass, this makes it look like foveated rendering works, but it doesn't actually save you any GPU!).

 

Here are a few screenshots (taken from Varjo software, which has a nice ability to capture both eyes). But again this is running the modified Pimax DFR software, but on my Varjo Aero.

 

Due to limitations on the forum, I cannot upload the full resolution images

 

The close-up image shows it better (red arrow to pixelated area).

 

 

With the special culling mode I described above, things are even more obvious:

 

 

Looking to the left, then looking to the right.

 

EDIT: Now with some performance numbers:

Looking at the FPS counter in Varjo Base (cause that's all I have handy, I don't have fpsVR). This is without restarting the game because I set a hotkey to enable/disable it on the fly. So it's the exact same scene/view compared.

 

DFR OFF

 

 

DFR MAXIMUM

 

 

So it's definitely doing something I would say. Note that I haven't tweaked any settings in the game so idk what I am doing ?

Edited September 15, 2023 by mbucchia

[1PL-Husar-1Esk]

@mbucchia Il2 has own in-game fps counter if you are not familiar - the backspace button 

[mbucchia]

Here's the utility if anyone wants to try: mbucchia/PimaxMagic4All: An adapter to make Pimax Foveated Rendering ("LibMagic") work on other headsets. (github.com)

 

I've tested it in DFR mode with a Varjo Aero and FFR mode with an HP Reverb G2. I have not tested "long term stability", so hopefully no crashes.

 

We shall continue discussions about this on the other thread:

For me I've narrowed it down the in-game settings FXAA and/or Sharpening checkbox. If I have either on, or both on, I'll get a crash to desktop soon after entering flight. 

 

With these settings I've attached I'm able to do some very heavy custom and quick missions even with fpsVR running (though I did upgrade my fpsVR which may have fixed its issue). However I've only done about 30 minutes of furball action, hoping someone else can confirm if this is repeatable.

 

Since @Charlo-VR you mentioned you ran with Sharpening before, I'm wondering did you still have it on after your eye tracking firmware upgrade and during the time you had crashes? Try enabling DFR and eye tracking again without Sharpening (and ensure MSAA is selected not FXAA).

Excellent find! Yes, a few days ago I had unchecked Sharpening (and have always run MSAA but with AA set to Off) with my last DFR tests and fpsVR did not crash for me any more, so I think you found the fix! ?

[Varibraun]

Sad to report that I am now testing Pimax Support again.  I received my replacement lens without any issues right before big eyetracking/DFR update.  Update went fine, new lens was great and the auto-IPD was an awesome new feature for me personally (my IPD is asymmetrical and the auto IPD adjusting for each eye independently put me right in my sweet spot, which has been difficult for me with every other headset requiring a bit of a compromise setting).  I was about to start really fiddling with settings and DFR and then:

 

After running fine for 2 days with the updated firmware and Pimax software, the headset just won't connect (Error 10500).  I even purchased a new USB power hub, just to be sure it wasn't the provided one, but no joy.  I am wondering a bit about a Windows 11 update that I think may have occurred in the interim, but from what I can tell from surfing online the 10500 error doesn't seem to suddenly be impacting a lot of users, so probably not.  

 

With no luck on my own to this point, I just submitted a tech support ticket to Pimax and will continue to surf the discord and web for potential answers.  Hopefully, Support will come through in a somewhat timely manner.  But I may end up back in the G2 for a while if it turns out to be a hardware problem and I have to await a replacement.     

[56RAF_Roke]

Bad luck Varibraun, how you get it sorted.

 

On a slightly different note, VR Optician are currently saying this re Crystal lens inserts: 

 

We plan to offer prescription inserts for the Pimax Crystal.

 

ETA: According to our prototypes so far, there is not enough space left in the Crystal for prescription lenses that work with all lenses Pimax offers, that is compatible with eye tracking and that has a reasonable good chance to work for the majority of face shapes. We continue exploring some more ideas, and plan to have another update end of September.

 

I'll be needing these, so looks like I'll be delaying my order a little while.

 

Thanks to all those who've looked into the DFR situation. The fact that its working and helping a little - even around 10% - is good to know. Still envious of those DCS types though with Quadviews...

[Charlo-VRde]

@56RAF_Roke I swapped out the Crystal’s face gaskets with a 16 mm pu leather Vive Pro face gasket, which allows just enough clearance with my VRRock prescription lenses that my eyelashes do not touch them. That face gasket and an Apache strap now make my Crystal comfortable for simming for hours.

 

I’ll be curious if the wider FOV lenses Pimax is developing will be compatible with my VRRock prescription lenses.

[TAIPAN_]

@Varibraun I also had error 10500 initially and had to change which port on the motherboard I had the hub plugged into (apparently a different controller on the motherboard), as well as reboot my system after the software update.

 

There are also reports of users having to unplug extra monitors. The connection between the PC cable and the hub is also very loose and prone to moving around. Duct tape works

 

This error is pretty common with a few solutions discussed on the Pimax Discord & Pimax reddit. 

 

However I assume you've probably tried alot of these fixes.. Just posting in case not, the Pimax Discord tends to have helpful smart users. 

 

@Charlo-VRregarding the wider FOV lenses, I have a worry because the tool tip on eye tracking says it only works with 35ppd. I hope they update the software/firmware to make eye tracking work with the new wide FOV lenses. The last thing we want to do is to be swapping lenses when switching between games that favour eye tracking vs games that favour wide FOV.

So in the end DFR in IL2 has failed me

 

Even though these two settings off allowed me to get on with some missions with DFR, it's not enough for all situations.

When I do something heavy like a mission with all the planes on my own MP server, or a heavy scripted mission, or I take the headset off and pause to go answer the door for a while, it still tends to crash.

 

I tried ALOT of things including re-verify of files, removing mods, skins, resetting nvidia, new drivers, all kinds of setting changes but it's just not stable like other games are with DFR.

 

Turning DFR off, the missions that failed now work fine. Since it's only a small performance benefit I'll leave it off for IL2.

It's just annoying to have to manually change a setting in the driver whenever I start or finish the game, since this is the only game I'll have to disable it for.

This intrigued me, because I thought the independent eye settings on the advanced tab were for manual adjustment only.

I always thought the Auto-IPD will only set one figure, ie the distance between the eyes.

 

I asked on the Pimax discord, and they kind of answered in a roundabout way that it does not set these offsets that they are only for manual adjustment.

Might be placebo or maybe the vertical headset adjustment overlay that helps when you put it on could have helped you, unless the guy that answered me was wrong..

Thank you Taipan, I appreciate you pointing me to some potential solutions.  Yes, so far I have tried moving the USB and DP connections to different ports (on the hub and the MB), reinstalling the Pimax software, a different powered USB hub, and have been checking Reddit and Discord.  If I have some time today, I will keep trying - I think I saw Calvin from Pimax on Discord recommending to find ALL of the Pimax related files for deletion before doing a fresh install.  But it is odd that it worked for me on a couple of occasions with the original update before refusing to connect.  That's why I wanted to get a support ticket in, in case it is a cable issue and I have to get in line for a replacement.  Bottom line - I appreciate your suggestions.

Yes, maybe it was a combination of a placebo effect (since I thought it was adjusting IPD for each eye) and that the auto IPD feature, plus the vertical adjustment reminder was a little more precise than my manual adjustment with the button.  My time for testing it was limited due to the connection problem, and I can't currently verify the auto setting vs what I had been using manually with the button to check it.  I will follow up on this once I am again connected.

I've gone back from steam vr and foveated rendering to jump open xr.

I do need to decrease settings in IL2, but I feel it just works smoother.  Especially in fast action of close up fights. I just find the details on the enemy planes clearer and better.

"Q: Foveated Rendering seems to be working in the game, but I am not seeing any performance improvements.

A: Foveated Rendering can only help if your game runs into performance bottlenecks through certain parts of your GPU pipeline. If your performance bottlenecks are elsewhere (eg: limited by CPU performance), then Foveated Rendering will not help you."

 

I understand the quote above to mean that DFR might provide benefit

if, for example, gpu frametime is twice cpu frametime, but not if cpu frametime is greater than gpu FT.

Yes but there's many easy ways to push your GPU frametime up, eg turn on MSAA, turn up SS, enable other eye candy etc.

 

So if you're not constrained currently, what it gives you is better eye candy (as long as you don't pick CPU bound eye candy).

 

The catch is the SteamVR type of DFR is using VRS (variable rate shading) which only benefits some types of graphic processing. I don't know the full technical details, but you should be able to find if interested in researching.

 

The other type of DFR (QuadViews) that is used for DCS with an addon tool can actually put different levels of SS and Sharpening on the gaze view and the peripheral. Unfortunately that tool only works in two games so far (DCS and PavlovVR).

 

In any case, my DFR is off for IL2 because IL2 can't run stable when things get complex.

Pleased to report that Pimax Tech Support has my Crystal flying again - just in time for the Nieuport 17.  Very good experience with them, they worked through a software/USB conflict for me remotely.

Anyone know what "procedures" this dialog in Pimax Play setup is referencing? I've not previously encountered one like it.

Hello, guys!

 

I bought the Crystal and  wanted  to try IL2, that I have been playing  with joystick for  some time. I know, it is not  easy  to helpa complete noob, but , please:

Write to me step by step guide-

 

I got  Pimax  Clien StemaVR playing  other games /ALyx  etc/ with 0 problems. But I hav etried to run IL2 to no luck- enabled "playin VR" in STema  and  di not see the option  how to react in VR. /no controllers, nothing/.

Pimax XR- I hav etried   as  well, here I could not event run the game -Pimax XR on  Pimax XR as the renderer, infused that *.dll  in the game, no luck ,

 

Many thanks for your help.

Hi, you might have selected previously to always launch in flatscreen mode.

Go to Steam properties on IL2 and change it to ask before starting, or to VR mode here:
