Whenever I go to my settings in game and back out, my VRAM usage goes from 2000ish/4000ish to 6000ish/4000ish. This renders the game unplayable, causes me to lag, and I have to quit for the settings to reset. I have a MSI GTX 970 (older I know but can run the game just fine). I am not sure the cause of this bug, I have the in-game overlay disabled.
