May I ask what wattage power supply you're using? Thats the only thing I can think of that is causing my issue. Cyberpunk runs perfectly smooth. Im wondering if the GPU is trying to draw more power when using VR mode on these Flight Sims. I am using an 850w power supply but should have my 1000w tomorrow. Its frustrating cause DCS is pretty much the only game I play. I even tried a clean install, new and older drivers. I even tried DCS in 2D mode and it was perfectly smooth with around 110 FPS maxed out. Any idea would be appreciated.
AMD 7900
MSI 4090
GsKill 6600 16x4 (I even dropped to 2 ram modules just to check, didnt help)
