From last few days I am having this weird problem while playing any game suddenly after a minute or so the gpu vram memory usage becomes completely full (not just one game but nearly all games including light games like fifa suddenly vram memory usage goes from 2gb to 4gb) and then is starts stuttering like hell , now when i alt tab out of the game it changes to normal for sometime and again the same spike happens when i play the game for some time (a stuuter happens suddenly maxing out the vram usage) . Please help, if any expert is out there.
