I like the VR performance of the new patch.
If you want 90 FPS all the time there are other sims with simple graphics that do that for you in VR.
I prefer good visual experience with low FPS now and look forward to the hardware developments of the years to come.
Sure all optimization that is possible should be done.
I have settings with 60 FPS for singleplayer and I also enjoy multiplayer even if I have only 30 FPS on the ground.
