FidelityFX SuperResolution to SteamVR games

[Globalnet]

Not the dev, but I think people should see this.

As far as I can tell, it works in IL2 but I haven't done extensive testing on it. I can make out maybe 10-20% more frames on higher resolutions than I normally run with some degradation in quality (mostly more jagged edges).

I've been using it just fine, see here:

The previous version did not work in IL2, i'll have to give it a shot again.

It worked well on other sims though, so looking forward to it.

exactly.  I used the newest RC2 version, and flew for about 4 hours yesterday.  No issues.

Is it easy to install without screwing thing up?

Extremely easy... just remember to backup the original .dll, in case you wish to go back (but you won't).

So just exchange .dll in bin/game ? That's it?

do these steps:

- download the fc2 zip file

- in your current ../bin/game rename the current openvr_api.dll to openvr_api.dll.orig

- then from the fc2 zip file, copy the openvr_api.dll & openver_mod.cfg files into your ../bin/game sub-dir

 

give it a whirl.  If you don't like then you can remove those (2) files and rename your ".orig" file back to it's original name.

just installing new .dll from the Win64 folder ( and the .cjg file recommended,)appears to have mad a noticeable difference .Its difficult to measure the amount of change , but I’d estimate that there has been a 10-20% improvement in general. Specifically my aircraft interior & exterior is better defined - even small jagged edges are gone or much reduced, Aircraft seen from my view in cockpit are also clearer. Gone to a large extent is the moiré pattern seen on some parts of the aircraft before as well as most of the sparkle sometimes seen in cities on the ground. The only thing that didn’t really change or improve is shadow definition which even at high definition is still a bit blurry. 

All in all am very pleased.

Hey guys,

There are two folders that the openvr_api.dll reside in. 

bin/viewer
bin/game

Which one specifically, should be replaced?

Ok I just verified the correct directory is 

bin/game

I enabled debug and confirmed log creation and debug viewer incl VR HMD

[javelina]

Indeed, that's where the install goes.  bin/game

I just copied the files in and am about to give this a go. 1080ti and a reverb G2.... Fingers crossed

 

The results are great. Where I was getting 55 -60 fps, I am now getting 75-80....happy camper.

What VR HMD, what resolution in VR and render scale are you using in the config? Just curious.

I also think I still prefer in game sharpness over the sharpness tune in the config - not sure how performant or effective it is visually even with debug

As mentioned, I'm running a Reverb G2...system is a Ryzen 3800x, 32GB of DDR4-3000, 1080ti

 

The 1080ti cannot keep-up with the G2 at full res so I'm running the resolution at 56% in Steam VR settings (2372x2316 per eye) Game quality settings are as follows:

Woah why are you capping your target FPS to 60? Does the Reverb run 60? I would be shooting for 90 fps at least. I personally run the Valve Index at 90, I find SSAO, Distant Buildings, Reflections, Grass, and Shadows to be FPS killers. Really surprised you run that at 60 fps for VR

Because I took that screen shot while running my flat screen which is a 60Hz 4K LOL, sorry I was too lazy to boot up in VR. In VR it runs as I described above...75-80 at low altitude...caps out at 90 when at high altitude...but it always did that even before installing this dll

[BBAS_Tiki_Joe]

I gave it a try system:

VR: Valve Index

i9-10900kf

32gb DDR4

3080rtx

 

I found that my fps skyrocketed (went from 65-90fps) Note:(*I can get a solid 90 by decreasing my settings and res, but anything above 65fps doesn't bother me for some reason like it does others, I like the quality over performance.) - to (115-130)  but I was getting really bad blur, like the resolution was decrease or that there was a lot of ghosting. I also felt like a bunch of micro stuttering was happening to the point of getting motion sickness, which is something I've never experienced. I did not change any of my settings between the installs. Just wanted to report my experience, I don't know if there is something that that I would need to change in my settings to maybe get more out of it.

 

Edit(to add):

My standard settings are:

Steam VR: 100% Res 2468x2740@120Hz

 

And here is my in game settings:

Question? So my fps shows two numbers, a top and bottom number like in the picture 90/45 which is actually the FPS?

Top is FPS, bottom is FOV.

Thanks! Always figured the top was fps, but never could figure out what the bottom number was.

Well. After struggling with my HP Reverb G2 working with my RTX3060ti, with frame rates never getting much above 45fps. Plus the steam application constantly crashing the game, I finally decided to give this a try.
The install was easy enough and it made a mild improvement, still just above 45fps, while at least not crashing. But, upon startup, it stills brings steam-VR onto the desktop upon startup and if I try to close it, it wants to close the game.

However after discovering that I had settings on MSAA for some stability through steam-VR, I flicked it over to FXAA and WOW!
Frames now mostly 90fps  and only going down to around 45 hard manoeuvring low over a city or taxiing on an airstrip.
I even turned 4K back on and it kept the mostly 90fps

Massive difference for me in making a smoother game.

Thanks fellas. I have been struggling for 7 months with this and now it is a mile in front.

Cheers.

awesome M8, great to hear!  I love this Mod.

Will try it and back with report.

Anyone know whether this works with Oculus and/or Opencomposite?

Ok, I tested and.... my feelings are ... confused,

Personally hard to tell me about FPS boost (but I have good GPU). With default settings of this mod (now its openvr_fsr_v1.1.zip) the picture for looks awful, too many "stairs" and the quality of picture is worse than default (I play in my G2 on 2600 pxt in Steam VR, so more than native). For me, the rendering image (on default level 0.77) is not acceptable.

 

However I tried 0.89 setting and on this level is a lot better, but I don't see any FPS increase either (without mod I have 90FPS in 90% of situation). Maybe I stay with this mod to check it more but with "renderScale": 0.89, not worse.

 

What is good it works also with DCS.

90FPS is the maximum framerate of many VR sets, so if that's the case for yours as well, you'll never get any more than that. What FidelityFX does, is reduce image quality at places it doesn't matter much, to gain FPS. It'll never make the game look better. Therefore, if your FPS and graphics settings are already at maximum, there's absolutely no reason to use it as it can only degrade your image quality for no FPS gain in return. If either or both your FPS or graphics settings are not yet at maximum,  FidelityFX might enable you to run higher graphics settings while maintaining FPS or increase FPS while maintaining graphics settings.

I have just such feelings, mostly I have 90 FPS (so like G2 RR, its normal) so no reason for this mod for me but it may be fine solution for owners of the other GPUs.

Well, it can also be used to gain more visual clarity at similar FPS too by using the current resolution as the internal resolution from which FSR upsamples the output picture.

Of course, frametime would increase by the runtime of FSR, but I assume one can find a good balance with an ultimately better image.

So fsr only works with steam version of IL2?

As far as I know, IL2 requires SteamVR to play VR anyhow.

 

Not sure if SteamVR also works with non-steam games though, but FSR in itself has little to do with Steam. If you can play VR now, you should be able to use FSR (but mileage may vary).

[loska]

Thx m8. I tested it yesterday. Works?

Can anyone with a Rift S report  whether the performance gain from this outweighs the performance loss of having to switch from Opencomposite to SteamVR?

I have an Rift S, and i dont know if using this program and opencomposite will improve ( more ) our performance.

With my Rift CV1 I found that it doesn't outweigh it but brings it back to about the same level. I found this to be worth it because using SteamVR enables the use of VRNeckSafer and thus allows you to turn around far enough to see with the reduced FOV.

Having control over the sharpening can help with tuning the settings to offset IL-2's poor visibility in VR so there may be some benefit there too.
