Useful info from the creator of OXRTK, mbucchia

  • OpenXR Toolkit foveated rendering has no CPU cost but a lot less GPU gain
  • Quad Foveated Rendering views is much higher gains on GPU but high cost on CPU

So decide which to use based on if you are CPU- or GPU-limited…

After more testing, I think I found the best settings for my hardware.

QVFR didn't work for my older CPU, so I went back to the OpenXR's Toolkit fixed foveated. Then I switched from Oculus ASW to Turbo Mode in OpenXR Toolkit, then turned on DLSS in quality mode with sharpening slider to max (1).

This combination gave me better performance with slightly better visuals. Nothing amazing, but it was noticeable better. 

I remember testing Turbo Mode some months ago and discarding it as the artifacts were bad. I don't know if it got better or my perception is wrong, but now the visuals seemed better and the artifacts were not worse than the ones you see with Oculus ASW.

PROS:
- Slightly better performance
- Slightly better visuals in general
- Almost no terrain stuttering (this is the most important for me)
- No more shimmering

CONS:
- some minimal but annoying ghosting.
- no way to measure frametimes as Turbo Mode ruins benchmarking tools

I will play with these settings for a while see how they perform in complex missions with a lot of units, but I think I now have headroom to crank pixel density a bit more, from 1.15 to 1.25 perhaps.

I haven’t seen much posts pro-TAA. However, I have to say that a quick test showed me the best visuals with TAA only. I always noticed the shimmering in the F14 cold start in the Caucasus on the wings of adjacent aircraft. With TAA it’s gone!! Very happy about that. I guess the only cons is a little bit too of ghosting happening now. Still, I probably prefer that to shimmering. 
I have tried all AA methods and all upscaling methods. Best visuals are TAA with no upscaling for me.

I'm having great results with TAA and virtually zero shimmers. The only downside is the "fiery phoenix" ghosting effect, which sometimes occurs, but I rarely notice it unless I'm low and fast or looking out the side of the canopy and pulling hard. Definitely better image than DLSS or DLAA for me, with a 0.2 sharpening factor.

I love TAA for still/slow moving scenes, but it produces some strange and annoying artifacts especially during take off and landing and in rapid moving scenes.

After testing alot, I have landed on DLSS Quality. I am running 3850x3850 resolution and the artifacts are kept to a minimum. Also running quad foveated rendering.

Due to DLSS I can increase the view distance from medium to high (I can’t stand the buildings popping up like mushrooms on the shorter view distances).

Now able to run 72Hz stable frames without reprojection.

Guess there is no magic settings, just personal preferences and hardware limitations.

I've had the same concerns as a lot of people here. DLAA and DLSS are nice but the blurring on aircraft and on MFDs such as TDC movement is really the only downside. I tried going back to MSAA but the seeing the shimmer again has made that a no go. 

This has been the update to finally drive me towards trying 60hz with a Reverb G2, it took less time than I anticipated to filter out the flickering. Prior to this I was pretty happy with 90hz and Motion Reprojection, the artifacts rarely bothered me. However, 60hz with DLAA 130% render resolution is providing a nice balance of clarity and smoothness.

Schimmering.
Anyone have photo/bideo example tò understand?

I suppose I'd say it like this:
Blurry - Difficult to make out detail or text, like with a lower resolution
Ghosting - When you need an object under motion leave a ghost of itself behind as a trail
Shimmering - The strange edge artifact/pixelation you often see on the horizon or on clouds in VR when using no AA or using MSAA. TXAA and DLAA seem to fix it.

I try dlss quality with virtual desktop beta(with openxr support) in godlike supersampling and for me the quality Is accettabile. I can read the mfds . It similar for me tò msaa 2x but i have some schimmering/flickering....(slight movement in some portions even in stationary things)
On the Mission f18 cold star supercarrier i see schimmering also on the sheep crew.
what can I do to decrease it?

If you previously ran through SteamVR: Remember Godlike supersampling is not very high when you bypass SteamVR (usually SteamVR has slider on 150% as default together with VD). You need to increase resolution in either in OXRTK or by changing pixel density in DCS (I recommend the first).

If you are thinking about shimmering, yes it does.

So  Reverb G2 + 4090

Do I use Quad Foveated  or delete it?

I did apply it a while back but I dont see anything within XRtoolkit for it any more.

Regards

With your CPU + GPU combo I would uninstall QuadViews and use the foveated rendering inside OXRTK. Can be uninstalled via add/remove programs.

Is it because the CPU is old? I have a similar GPU and using QVFR. Should I go back to OXRTK FR?

I am super confused now also.

Tested the Apache over Paris in Normandy 2 with DLSS Quality and VR resolution 4320x4320. High visibility range, flat shadows and most settings at high.

Did two rounds and there was surprisingly little difference between the different options:

QuadViews OXRTK Fov No foveated rendering
 58 fps  60 fps  56 fps
 58 fps  58 fps  55 fps

I was expecting a lot bigger difference... 

Here is the track file:  https://1drv.ms/u/s!AoRLvddry46oiecXADch97Nf4afNCQ?e=fC17cO

Have not tested with other AA types or without any AA...

Added Foveated Rendering and its the best VR i can get at the moment..

Apache Caucasus instant action...12.8 G Vram

Huey Caucasus instant action....7.8 G Vram

Monster differences between aircraft.

So many hotfixes and fixes at present so difficult to get it as good as it can be....patience Ithink is the name of the game.

Just did a test 10 min ago.

HP G2 / AMD 5800X3D/ AMD 6900XT OC

1v1 BFM F14 vs F16AI over Persian Gulf

Quadview enable - 62 fps

Normal - 55 fps

Improvement 7fps may not be alot but in my case push me over 60Hz. It is substantitial for HPG2 setting at 60Hz

I try quadview and Also ffv of oxrt ....the frame are the same without and i see bad ...so i unistall both.
The big frame came from dlss quality and i can see good on all the lenses.

I have only One problem with the apache at low level i can see lag / stlutters on the terrain ....i have good fps but 70 global latency of virtual desktop.

I'm glad I did not rush upgrading my RTX 3080, and waited for Foveated Rendering support as well as DLSS. Getting a steady 72 fps with my Quest Pro with shadows on Medium (which I never was able to have). I keep supersampling at 1.0 everywhere except in the Quad-view-foveated focused area. It looks even better than with MSAAx4, but almost zero of shimmering.

OTT

- SS 1.0

- sharpening OFF

- view multiplier 0.85

Quad-view-foveated

- SS in the focused area 2.0.

- sharpening 1
