performance

[Nibbio]

My benchmark is an 8 vs. 8 dogfight cloudy skies autumn stalingrad. Managed to run high graphics with 4xAA, .7 dynamic resolution, without ever having the dreaded ASW kick in. Apparently SS is much less efficient than in game AA, so that's down to 1.0. Think I'm finally done fiddling with graphics options now.

I7 3820 OC (below the OR minimum requirements), MSI GTX 1060 3Gb

SS supersampling or pixel density is a real performance killer. A very expensive way to get AA. I suggest leaving it at 1.0, unless you really have horsepower to spare

[Wolf8312]

Interesting point to be honest I agree AA does work much better though I wasn't sure which on AA or SS is more demanding so I use a blend of both! You're right though I've stopped messing with the settings now too, and just enjoy myself playing the game. AA on 4 though is a little high, I suggest if you use 2 like myself you will soon get used to it, and find it to look great. Can't stress enough though download the terrain cfg file in the link and OP provided it helped me a lot and looks far better than the vanilla settings even with AA off.

[Nibbio]

What I stated is not entirely correct.

Low graphics, terrainx2, 2xAA and 1.2 SS (PD) gives me consistent 90 fps, hud off, .7 DR. ASW never kicks in, and it's good enough to ID planes and navigate

[Wolf8312]

To be honest for me in VR with terrain at x2 or x3 or x4 I cant work out what the difference is so I just set it to normal!

[SakerVVS]

Are you guys playing multiplayer? Are these settings good for spotting planes easier?

[Nibbio]

Planes are way easier to spot in VR than on a monitor for me, bur hard to identify. At longish range, like 6 or 7 km, they start to blend with the landscape, but when they are closer they are easier to see and follow. ID is a bit more difficult. Also noticed that ground targets like vehicles appear larger in VR, definitely more realistic.

Now I have no AA in game and 1.3 SS.

[Remontti]

In multiplayer (WoL) many times when there is combat going on and planes flying around you the ASW kicks in and fps is down to 45. But the fps drop doesn't show when looking processor graphs from CPU and GPU. My GPU is running steadily at 60% and CPU is at 50% (short spike at 60% but nothing above that). What's up with that? Why does the fps drop when CPU and GPU doesn't seem to be fully utilized? These drops are far more common in multiplayer. In offline the fps stays quite steadily in 90.

 

In WoL without VR fps stays at 100 limit and without limiting is goes above 200.

 

Hardware can be seen in my sig.

My theory, but don't quote me on this>

 

Rift software measures headroom, and if it believes you won't reach 90 with enough headroom left in reserve. It will lower you to 45fps and kick in ASW. So, if your at 45fps with Asw on, and say a 46% gpu load. It has not deemed you worthy of 90+reserve and you'll be stuck at 45fps.

 

And yes multiplayer on a busy server I find much more demanding than offline playing.

 

On a side note, I seem to get a performance increase when turning off hyper/threading. Can someone with an I7 doublecheck me on this? I'm positive it's not my imagination but curious if it has something to do with my rig or with il2 in general.

Hi Guys,

 

Pulling my hair out trying to get this running well. Just upgraded from an RX480 to MSI Gaming X 1080 and I expected there to be a big jump in quality  but the game still looks like %^&* with wiggly crosshairs and jaggy edges. Frame-rate is anywhere between 20 and 45. Very disappointed with my purchase as this game was one of the main reasons for the upgrade. Everything else I play works great (except ETS 2) with my system.

 

System specs:

 

Ryzen 1600X
​MSI 1080 Gaming X

MSI X370 Carbon Mobo

16 Gb DDR 4 3000Mhz RAM

Samsung Evo SSD

 

 

I've tried all sorts of things mentioned in this thread and others. I find the Nvidia Control Panel horrible to use after using the excellent ATI Crimson. I've set everything back to default because I was going round in circles with it.

 

Can anyone with a similar rig help me?

Is the 20-40 fps your getting with hud on or off?

 

"h" key while in game if you haven't tried it already.

[Barnacles]

How do you disable ASW, as I think I'm having the same problem as Aerodyne.

[Aerodyne]

20-40 with hud and at or below 44 without. It's definitely way below ASW. My eyeballs are ruined!

 

Settings I'm using are:

 

Balanced/High (seems to make no difference)

Sharpen ON

SSAO OFF

HDR OFF

Distant Grass OFF

Distant Ground Detail (or whatever it's called) OFF

AA tried all settings, seems to make no difference.

 

I've even re-set windows today and re-installed everything and it's still the same, though the crashes have stopped. (I think that was down to sound driver installs clashing and nothing to do with this problem)

 

I've been at this all day, it's like gaming back in the 90's!

Aerodyne, In your shoes I'd run some Gpu and cpu benchmarks, compare results for each with similar hardware and you'll likely be able to rule out one of them. Then dig one step deeper in the right direction.

 

For comparison I'm currently running a very old i7 920@3.8 ghz, with a borrowed gtx1070. At medium settings. Asw kicks in and lowers me down to 45 only when close to the ground or if there is lots happening around me. Every step I bumped up cpu ghz, gave a noticeable framerate increase with some ai aircraft around.

 

Your rig, while not the ideal ~5ghz quadcore, should be doing plenty better than mine, so I definitely suspect something is wrong. Keep us updated if you find something.

Balapan compiled this sheet from some testing over at the Russian forum. They all used the same track, settings and measured average fps with fraps.

 

https://1drv.ms/x/s!ArOH6hv3WrGpiF2r8Vms_rCL8dKy

 

Not many lower spec systems there, but results seem to indicate that anything above 980ti/1070 will be bottlenecked (fps wise) by the cpu. I would assume a 1080/1080ti would still have the advantage of letting you use more of the Gpu-only features such as aa and ss.

Hi, yeah I get really good results in benchmarks like 3Dmark etc. and everything else runs beautifully. It's just this game. There must be something I'm overlooking.

[TP-Blackjack-]

How do you disable ASW, as I think I'm having the same problem as Aerodyne.

Install oculus debug tool, run this after starting the rift, disable ASW in the debug tool, start BoX. This should solve gunsight reticule and propeller distortion.

[dburne]

As of version 1.14 of Oculus Home, the debug tool in included in the installation files and no longer a separate install.

It is in the folder Oculus Diagnostics.

[Aerodyne]

I have Oculus Tray tool, I didn't know about the diag folder, will try that.

 

Thanks for the suggestions, guys.

There's definitely something strange going on here. The performance of your system should not be so low.

 

I suggest you download MSI Afterburner that allows to check the CPU and GPU usage in real time. It might give us some clue to the problem.

 

I would also try to create a baseline IL2 profile with Nvidia Contol Panel, and set everything as default or "application controlled".

You may want to check http://www.tweakguides.com/NVFORCE_1.html to better understand what each NVCP setting does.

 

I found that I can have satisfactory performance (89/90 most of the time, drops to 44/45 down low or in a big furball) by disabling in game AA, setting pixel density at 1.2 (via Oculus Tray Tool), balanced graphics, no grass and terrain normal.

I7 3820 and GTX 1060 3Gb, both overclocked as high as they would go (with custom liquid cooling on the CPU).

 

With these settings, MSI Afterburner shows that CPU usage varies between 30 and 40%, GPU around 80-90%. With AA enabled, or high/ultra graphics, GPU would max out at 100% and fps would suffer noticeably, which implies that in my case the CPU is not the bottleneck, albeit being quite old.

 

I also found that setting "VR pre-rendered frames=4" in NVCP gives me a significant performance increase, which stands to reason, GPU being the weakest link of my system.

There's always someone that will caution you against it, because it's supposed to introduce "latency" in controls, but I have never noticed anything of the sort. In any case, given that at 90 fps single frame latency is 11 ms, the most latency this could introduce is 44 ms. I think I can live with that. If my reflexes were that good I'd play Counter Strike, not BOX

 

As an afterthought, wonder if your CPU cooling works well. It could be that the CPU reaches high temps and this triggers some safety downclocking mechanism... Anyway MSI Afterburner will also report on CPU and GPU temperature, so you might want to check that.

 

Edit: it's called dynamic frequency scaling or "CPU throttling" https://en.wikipedia.org/wiki/Dynamic_frequency_scaling

"AMD employs two different CPU throttling technologies. AMD's Cool'n'Quiet technology is used on its desktop and server processor lines. The aim of Cool'n'Quiet is not to save battery life, as it is not used in AMD's mobile processor line, but instead with the purpose of producing less heat, which in turn allows the system fan to spin down to slower speeds, resulting in cooler and quieter operation, hence the name of the technology. AMD's PowerNow! CPU throttling technology is used in its mobile processor line, though some supporting CPUs like the AMD K6-2+ can be found in desktops as well."

I think coconut is on to something...  This comes from a thread poor performance 1080 Ti. 

 

"

Actually, there is a difference between flat mode and VR. In flat mode I can reach over 40% CPU utilization, if I leave frame rates unlocked. It's also rather unpleasant and stuttery when I do that, despite high FPS well above 100.

 

In VR with dynamic textures disabled (full), I tend to get stuck at 45 FPS with 60% GPU utilization and at most 30% CPU utilization.

 

In VR with dynamic textures enabled (0.5), CPU utilization goes up a bit. Not all the way up to flat mode, but between 30 and 40%. FPS stays up at 90. Until it can't keep up (flying low over the outskirts of Moscow), in which case it goes down to 45 and lower CPU utilization.

 

What I think is going on is that the devs have implemented a throttling mechanism in VR to keep stutters away at all costs. There is one we know of, the dynamic resolution thing, and maybe others we don't know of"

[Urra]

In multiplayer (WoL) many times when there is combat going on and planes flying around you the ASW kicks in and fps is down to 45. But the fps drop doesn't show when looking processor graphs from CPU and GPU. My GPU is running steadily at 60% and CPU is at 50% (short spike at 60% but nothing above that). What's up with that? Why does the fps drop when CPU and GPU doesn't seem to be fully utilized? These drops are far more common in multiplayer. In offline the fps stays quite steadily in 90.

 

In WoL without VR fps stays at 100 limit and without limiting is goes above 200.

 

Hardware can be seen in my sig.

It's difficult for vr because server software is single threaded and updates at 30Hz like star citizens (60 Hz would be better). The cpu is just waiting for info from internets during fights. We won't see an improvement for little while longer I believe. This is just my non-expert , couch expert opinion.

These results seem to correspond what I got when I tested the track. I wonder what kind of super computer is required to keep those min frames near 90 fps. In the linked chart there are guys with cpu clocks running at 4,9 and 5,2 GHz and their average fps don't differ so much from those with more modest overclockings.

The above information is correct.  First you must make sure ASW is turned off or you will be throttled for the most part at 45 fps regardless. Super Sampling 1.5 via Oculus debugging tool.  Tested no visual difference @ 2.0

 

Running the game in Ultra with everything on.  I wanted to push the card

4X SSAO

Sharpening

4X

Distant Grass

No HDR

 

With the Dynamic Texture setting at .5 you will get a big hit in terms of visual appearance regardless of the above settings.  Turning it back to full it does look a lot better with a bigger load on the CPU but who cares really.   On the ground in MP my average FPS was between 45 and 60.  After take off it bumps up to 90 and runs between that and around 60.  My GPU is hardly taxed at this point and it really has nothing to do with CPU load either which is around 40-60 percent.  There is some sort of internal throttling going on.  On these settings it's much nicer looking and it runs very well.

Well downloaded DCS last night and had a great few hours. I was running high settings and 1.5 SS. It ran beautifully, very smooth and a real sensation of speed when low down. Can't wait til Normandy drops.

 

Shame I can't run this as I have been playing since the first version came out. I can't go back to playing it on a monitor so it will be on the back-burner until this is sorted.

 

Cheers guys.

Is there a huge difference in experience between 45fps with ASW and 90fps without ASW ?

I only have a RX480, so never really hoped to reach 90fps.

You will likely get varying reports on this.

Personally for me, I do not see a big difference at all. When ASW does kick in for me, it is still a very smooth experience for me. I get some squiggly lines on the inside of the gun sight reticle, and the planes may blur somewhat as they pass by me, but otherwise it is still a very smooth and pleasant experience for me.

Now if one should drop much below 45 fps, then that I am sure would introduce stuttering and maybe not such a pleasant experience.

[SevenFifty]

Visually - probably no or not much.

But ASW is introducing some artefacts on fast moving objects and that makes plane identification much harder. Unless you flying attackers only you want to have it off.

[Don2one]

I'm doing a lot of simracing and i always have to turn asw off.

I always use these controls to turn ASW on or off. Anyone know if this working?

 

Control-Numpad1: Disables ASW and returns to the standard rendering mode. 
Control-Numpad2: Forces apps to 45Hz with ASW disabled. Depending on the application, you are likely to experience judder. 
Control-Numpad3: Forces apps to 45Hz with ASW enabled. Enabling and disabling ASW will help you see the effects of ASW. 
Control-Numpad4: Enables ASW. ASW will automatically turn on and off, depending on whether the app maintains a 90Hz frame rate.

Fwiw, check out the Oculus Tray Tool by ApollyonVR over on the Oculus Forums. He has a pinned thread on the General Forum. Great tool you can set to run at windows startup, you can use it for things like setting up game profiles for ASW, Pixel Density, etc...

I have it and have been using it for some time, love it.

[Don2one]

Awesome, i actually only play 2 games. I will try to see if its something for me. I always have my fps on 45FPS very annoying and something when i look back it goes black(think it has to do with the low FPS)

 

Hope this going to work for me! Thanks for pointing me to the tool. Knew of it but really never used it because i only play one game:P..

 

Now 2 hehe

I have ASW off, and this can still occur in the event that your frames drop. I find the only way to prevent it is to keep frames at 90 FPS

[Tom25briklebritt]

What do you recommend?

 

I got a Oculus, GTX1070 and a nice CPU.

 

- Better to use "Dynamic res factor" below 1,0 or trying to lowering gfx settings to reach constant 90fps?

- Use ingame AA or Supersampling through "steamvr.vrsettings"? (I set 1,3 Supersampling)

- ASW always to OFF only when not using "Dynamic res factor", or set it always to OFF with BOS?

 

Would be great if anybody tells me what works best with BOS. THX
