I’m also waiting for a 3080 card. Did you get your O+ running smoothly with your 1080ti? I’m running the G2 @ 60Hz with OXR Preview=ON, OXR=80%, MSFS =70% and most of the other MSFS graphics settings at Med/Low. FPS varies from 20-30 FPS so the reprojection feeds the G2 60 FPS. The G2 @ 60Hz was a little annoying at first during the bright daytime flights, less of an issue with dawn/dusk flights. I’m used to it now but when I get a better graphics card, I’d prefer to be running the G2 @ 90Hz.
I may dust off my Samsung to see if I can increase some MSFS graphics settings and still have smooth flights. It might turn out to be a better experience with the 1080ti even with the Samsung screendoor effect (I’m not doing much night flying so the OLED black blurr isn’t a factor).
