Curious as to what y'all do to get the best framerates in P3D V5 VR. I have a Rift S and while I can get a steady 40 fps (1/2 the 80 max) with simpler planes, over really nice scenery I get closer to 20-30 fps in more complex planes like the DC Designs F/A-18E. Flyable, but jerky updates.

Turning off automobile traffic helped a lot, and I haven't gotten around to replacing any stock AI yet so no added overhead there. Running OrbX PNW and the Drzewiecki Design Seattle City/Airports X. I realize I'm adding to things with the add-on scenery, but just wondering which settings have the most effect on VR performance so that I can enjoy the best compromise between performance and realistic scenery.

Would love to hear what graphics, detail, etc. settings y'all have found have the most direct effects on P3D V5 framerates.

Computer is a Core i9-9900X with an RTX 2080TI, so it's not anemic hardware at fault. :)

Run in steam vr mode, not oculus mode.

Godrays off, dynamiv reflections off. Care with tree and building shadows.

i fly complex planes over dense scenery snd am very happy.

dynamic lighting kills my frames in vr . Just found my memory was not set correctly at right frequency gave a big improvement. I use PD 1.6 to 1.8 depending where. Turn off ASW  in v5 it is broken .Unlimited frames or limit to 120  no vsync and use pre render for v sync .FFTF helps me as well .

Definitely definitely this. 

Also

1. Use Oculus Tray Tool. With SteamVR you can run smoothly with good ASW at 30fps ( actually 27) if necessary if you cannot hit 45 (actually 40). I think the Oculus implementation of ASW is faulty in p3dv5. SteamVR video res set at 150%

2. A bit of voodoo, but turn off the "maximize to fill screen" checkbox in p3d.

3. Process Lasso. I have an 8 core AMD, run p3d on cores 4,6,8,10,12,14 and everything else including Oculus and SteamVR on 0-3. Don't let p3d hyperthread.

4. nVidia inspector, Sparse Grid SS x 4 with MSAA x 4 cleans up the sparkle beautifully. Clear your shaders after any change to nVidia inspector and you MUST have MSAA on in sim for SGSS to work.

5. Framerate in P3d set to unlimited or maybe 120. 

5. Prerender frames in VR settings probably helps.

Can you elaborate ?  How did you determine correct clock setting?

thx

Using my motherboard gigabyte utility .

So it turned out the killer was OrbX Vector. In P3D v5, having the road networks, railroads, etc. turned on decimates performance. Turning those off (but keeping the coastlines and a few other light-touch additions like golf courses), my frame rates smoothed out and mostly quadrupled.

It's now quite playable. Even in the worst-case scenario (Seattle area with details cranked), when the frame rates drop, the updates are still smooth rather than stuttery.
