I just joined the beta and installed SU3 for the first time.
Before SU3 (non-beta), I was testing with near-Ultra settings on a system with i7-13700K, 64 GB DDR5, NVMe SSD, RTX 5070 Ti (no Frame Generation), and a single 2K monitor. In this setup, I was getting around 80–90 FPS over small towns and rural areas.
Normally, I use a 3x2K monitor setup with DLSS Quality and get 40–70 FPS, depending on the scene. In VR (Meta Quest 3 + Virtual Desktop), performance was around 30–45 FPS.
After installing SU3 beta, I’m seeing only 11–15 FPS in the main menu, 2–4 FPS in VR, and 10–13 FPS in external views, even with default Low-End preset. Interestingly, in the cockpit view of the C172, I briefly get 50–60 FPS, but it drops again in external view.
I already:
Reset all in-game settings (graphics, camera, etc.)
Removed everything from the Community folder
Double-checked NVIDIA settings (latest driver installed)
Rebuilt the rolling cache (changed from 64 GB to 32 GB)
GPU utilization is at 100%, but performance is still very poor. I also noticed strange visual artifacts around aircraft lights — circular glow effects that weren’t there before.
Additionally, during Auto Pause, the sim drops to 7 FPS.
What could be wrong, and how can I fix this?
Also, if I decide to leave the beta, is there a way to revert to the official version without reinstalling everything?
