Hi all, I ran into the same issue. The FPS drops to 1 after the the screen lock kicks in, i.e. after the number of minutes when the the screen locks. This happens since the update to nvidia 440.31. System is centos 7. GFX card is GeForce GTX 1080 Ti. The effect does not show in identical system with GeForce RTX 2080.
Any help on how to resolve this is very welcome. [image: vgldrop.png] Am Samstag, 19.
