This driver seems to have fixed stutters with GSP, Allocating GPU memory seems to be a system-wide blocking operation · Issue #164 · NVIDIA/egl-wayland · GitHub and Micro stutter with specific config · Issue #1647 · flightlessmango/MangoHud · GitHub. But unfortunately my Alienware AW2725DF monitor still randomly looses video signal when using VRR with low FPS: No signal with VRR when framerate is low. This issue can be easily reproduced by setting Adaptive Sync to “Always” in KDE Plasma.
Edit: I also have the same issue as @debestinator11 with GTK4 apps that hang at exit.
Edit2: Setting NVreg_RegistryDwords=RMIntrLockingMode=1 with 575 and probably 570 drivers also fixes stutters issue.
