With your hardware, I’m wondering whether changing the following would have any perf difference:
Building: MED (1)
Grass (reste de la vegetation): MED (1)
Tex. SS: 4x4
Terr. Shadows: 256
Contact Shadows: LOW
Windshield Effect: HIGH
Reflections: HIGH
Lights Shafts: LOW
Cockpit Refresh Rate: HIGH (2)
(1) these are mostly vertex shader related and are impacting CPU/GPU/RAM/VRAM
(2) this is mostly CPU related and is impacting CPU/GPU sync
(3) the others are mostly pixel shader only.
On a 2070S + 9700K I can run the Index with SteamVR with these settings (yours + the changes listed), and with TAA100+SS124 which is about rendering 2.2K x 2.4K pixels per eye, at 22fps → 90Hz before WU3, and now at 18fps → 90Hz since WU3. I must say the latest(s) SteamVR with up to 6:1 motion smoothing is really working great for this.
PS: The only post-processing I find affecting legibility or sharpness is Bloom. It is nice an effect but the threshold is too low and this is causing for example EFIS text to be displaying with enough blur to make it undesirable to me.
