I have RTX3080 (EVGA FTW3), Ryzen 9 5900X, 64Gb of 3800Mhz RAM, 2 fast M2 SSDs, Reverb G2 - it’s a top of the line PC, it has to perform better than that! It’s borderline flyable in GA over sparse terrain, and unflyable in an airliner in a dense area.
I have waited for better drivers and performance to try again, and with latest Dev OpenXR I did. I got it to 22.5 fps and x4 motion reprojection. I guess it’s mostly smooth now in Cessna 152 lessons over sparse terrain. The problem it’s still not really good at all. In JFK landing challenge it dives below the smooth level and it’s all stuttery close to the ground. And very unstable - can crash VR when the new flight is selected, or get it to stuttery mess when it as OK just before.
I use all recommended settings - OXR 70 and tried TAA 80 to 100, medium-high VR settings in MSFS, tried all recommended sets. Tried HAGS on and off, all the rest of windows settings as recommended. Disabled virtual monitors in registry, set MSFS PC to full-screen lo-res 1080p (I have 4K monitor), disconnected 2 other monitors. Tried “official” overclock on 3080 and stable memory and CPu overclock. Created a .bat file to kill all unneeded processes and services when launching MSFS. Only launch after a fresh reboot. Other VR titles like Alyx just fly. Smooth and very high FPS. MSFS is a clumsy and uncertain borderline trainwreck… Sometimes (but not always) playable in GA. I tried MSFS VR first on a 3080 on 1.5 year old PC, and since upgraded almost everything - CPU, RAM, 360mm AIO liquid cooling, high airflow case, flashed the motherboard with fresh BIOS with USB fix.
What else could I try?
- Latest Nvidia driver 466.27
- Developer settings at preview On, scale at 70%, Reprojection Always On (Automatic was a mess). Runtime 106.2104.15001.0
- WMR portal 2000.21041.1051.0
- OpenXR 105.2104.13002.0
- Latest Windows updates as of today, including the KB5001391 that supposed to have fixed stutters.
Very disappointed. Any advice about what else to try is much appreciated!
