My VR Setup/Config & Looking For Opinions/Suggestions

[JSF_Aggie]

I have a new computer, a Reverb V2, and new to VR.  I hoping y'all could look over what I've done, and if my performance is what you would expect.  Please call out anything I've done wrong or should still do.  Appreciate your time.

New Alienware with Win 11.  DCS OpenBeta, Thrustmaster, McAfee, Mixed Reality Portal and OpenXR is all I've installed.  No DCS mods yet.

i9 12900KF, nVidia 3090, 64GB DDR5 @4400 mhz.

I've setup OpenXR per nikoel's OpenXR Guide thread.  Also installed the OpenXR Toolkit.

I turned GPU Scheduling and Game Mode OFF

Latest nVidia driver, with the following CP changes:  MFAA: ON, Power management:  Max Perf, Texture filtering Neg LOD bias: Clamp, Texture filtering Quality: High quality, VR pre-rendered frames: 3 VR variable rate super samping:  OFF

Everything else, left as default.

Running the Nellis, Hornet Free Flight mission, I stay at 90 FPS, per the DCS FPS display, with Motion Reprojection OFF, but looking at the terrain  at my 9 or 3 o'clock, it has an annoying amount of stutter. 

If I turn Motion Reprojection ON in OpenXR Tools and the OpenXR Toolkit, I stay at 45 FPS, but the terrain rolls by smoothly.  Motion Reprojection does cause some side effects to my cockpit displays, mainly notice it on my AA radar page.  I prefer it ON by far.  Syria, Hornet Free Flight mission, I stay at 30 FPS, but no stutter.

My DCS Settings:

I would start by turning Textures to Medium and Terrain Textures to low. You don't notice much difference from the air and these settings seem to have a large impact on fps.

Another FPS killer is Anisotropic Filtering.  16x vs Off will give you 8-10 FPS more, not to mention it does nothing to improve quality!  At least in a pimax.

Cloud at ultra will not make any visual difference compared to low but will also cost many FPS if you have lots of clouds.

Don’t be afraid to slide all this to the right with that AW-3090. With OXR and Motion Repo running 30-45 fps is no prob. My R11/3090 does it very well, I don’t watch the numbers anymore. Everything is smooth and the clarity is the best it’s gonna get. I honestly don’t think I can get it any better so I just fly !

And you can even do it in game, the sliders that is!

The combo Visib Range Ultra, MSAA 2x and Clouds Ultra might be pushing too much

Anisotropic to16x makes the image much better on my case (RTX 2080Ti + RiftS) and doesn´t mean a fps hit, how weird.

Depends on hardware but also on the test scenario.  I use the attached track file along with fpsVR and here are my results:

Aniso filter OFF : 58.3 FPS

Aniso filter 8  x  : 52.5 FPS

Aniso filter 16 x : 49.5 FPS

Image quality is very subjective but on my setup, I don't see any noticeable improvement with Anisotropic filtering on.  Only the FPS drop!

Thanks all. I’ve been tweaking the above and looking at all the info in edmuss’s tuning thread.
