Hi! If you have a 4090 with an i9-13900K, you shouldn’t need to reduce the refresh rate that low to achieve good VR performance without motion reprojection or even having to use DLSS… I’m on a i9-9900K OC’ed to 5.0GHz and a 3080 Ti and I lock in 36 FPS on 72Hz with a Quest 2 and get really great, smooth performance even in aircraft like the Fenix in busy (VATSIM busy) airports… Let me know and I can post up my settings if you want a bit of help tuning your rig. Things like OpenXR Toolkit do wonders for performance tuning, if you aren’t using it already.
