I know that VR has an impact on performance to some extent, but it's ridiculous in 1.5. The performance overall is a huge improvement in 1.5, but when it comes to VR, there are obviously some major flaws.
Here I am, flying in an area that should have a huge impact on performance, but in VR it's severe.
And here are my flying in a populated area without VR. I even zoomed out to increase FOV without it having an impact on performance.
ED really needs to take a closer look at this. I've no problems running other sims in VR. FSX, Prepar3d, Arma 3, they all work much better than this. Even if I run 1.5 with all settings set to low, I get some performance loss. Until you've figured out what's causing this problem, you should add timewarp to help ease the judder.
