there's a basic fix (and fix coming) for p3dv5 vr single pass rendering:

Can anyone here tell me how V5 is looking with Flight Sim Labs A320 or equivalent these days? I'd be keen to get my hands on it but only if VR performance would be playable my my 2080Ti and 7700K OC to 4.8.

@aidanlegras,

    Here is one data point for VR with v5 - it is somewhat faster but still not with a large margin of performance using reprojection=motionvector  at 45fps on the Reverb.

   My test case is as follows:              My PC = 9700K@5Ghz (win10 Build1903 18362.778)  + RTX2070 ( 445.87 )

KMRY from ORBX + Northern Cal from ORBX

Spring Day @1400 Fair Weather
Mooney with G1000  @10R

Graphics: FXAA=off, AA=4XMSAA. Ani=8x, TexRes=4096, Frames = Unlimited
          LOD=Ultra,    TessFac=High,Mesh=5m,TexRes=7cm, UseHighResTex,
          Scene Comp=ExtremelyDense, AutoGen=Medium,Veg+Bldg=Normal,DynamicVeg=on
          Water Detail=LOW, no Bath, NO reflections
          SpecEff=Medium
          HDR=OFF, DynRef=off, LandLights=on
          Shadow qual =LOW, Shadow Draw Dist = Low, Casting+Rec = both for Internal and External
          Cloud Draw Dist = 80, Density = Medium, Detail clouds, Vol Fog=on, Det Prec=on, Windshield effects=on
          Traffic - Gen Av=10, Road Veh=10
          VR=single pass

 

Prepar3D v4.4 FPS = 60     ( with reprojection=disabled for the test )

Prepar3D v5.0 FPS = 75->80   results in fairly smooth performance (minimal stutters )

If a more complex aircraft like Quality Wings 787 is used, then the Scene complexity for KMRY would have to be reduced to Normal or Dense.

 

Thanks again for your setting info. I bit the bullet and upgraded to P3D 5.1 primarily for use with FS Labs A320 and using your settings is pretty good so far, particularly the: Frames = unlimited which I hadn't even noticed before even though mine were set to 30FPS! 🙄

However, now I am having this CTD message when I select SteamVR (to switch over to VR once ready to go):

"Your virtual reality device reported the following error: VRCompositorError_TextureUsesUnsupportedFormat Prepar3D will now exit virtual reality.

This is then followed by: "Unexpected SteamVR Error, SteamVR has encountered a critical error."

 

Would anyone have any ideas?
