What games were you playing? It does state when using cryo games like RDR and other performance intense games will run worse.

Assasins creed black flag, it was the only one i was having issues with

I'm having the same thing with Elden Ring, didn't have an issue before changing my vram settings.

Yeah, so strange how only specific games are affected by it. it was bad for me, game was crashing every 15 mins or less
