So I took people's advice and used that performance tracker thing that XSOverlay has and it seems my VRAM is the main issue that is causing me to lag in full rooms. That shit was capped out (or close to it) almost the entire time.

So how exactly do I fix it so VRAM isn't getting fucked? I already cleared the 20gb cache thing and didn't help much. What are the options? also if there's mods that specifically help I'm down with that though I'd prefer non mod solutions
