Lag PTSD
Lag PTSD is like your brain is stuck in a time loop of bad frames and lag. You think every game is going to crash, even if it's running like a dream.
I just started my game, and I already think it's going to lag.
My PC is running Cyberpunk at 60 FPS, but I still think it's going to crash.
I got a new PC, but I still think it's going to lag like it's 2010.
