A few months ago this starting happening. Suddenly all of my games looked god awful and ran around 30fps. I've tried reinstalling drivers, manually selecting which graphics device to use, everything. I'm playing on an MSI gaming laptop with a 3060.
For reference, I have Helldivers 2 running in the background.
Nvidia overlay says that my gpu has 0% usage, 42 C, 210Mhz, 0.650V, 8W, 405Mhz. It also says that my cpu usage is around the 80% mark.
MSI dragon center says my gpu is at 40%, 61 C and the VRAM clock is at 6000 MHz.
Any help is greatly appreciated.
