Hello gods of science and technology. I got a new computer a few months ago with a Geforce rtx 4060 so I could gen AI slop. I would also like to play visual novels while I play games and shit but whatever is the active window, say Total War Warhammer 3 uses ALL AVAILABLE VRAM so the VN is choppy and likely will crash. A fucking VN can't run because Total War or Cities Skylines or Stellaris just has to take everything leaving the VN with nothing to run?

How do I tell them to fuck off and stop trying to steal every bit of Vram so I can run a simple VN in the background?
