I was getting poor performance when I was taxing at any airport when I used my Oculus Rift S. It was hard to use the simulator in VR mode because it was pretty bad. It shutters a lot. Even at 30 fps, it was hard to use. I went to the oculus software and switched off the beta version, and OMG looks like I upgraded my device. It looks so sharp and good. I got a performance boost. I downgrade to high for terrain and ultra for clouds since I flight IFR anyway, and it is a new sim.
I also switched the simulator to full screen and not more CTD. I was getting a lot of CTD in window mode when using VR Mode.
