Look at the guides section, modding/configuration.

thanks

What exactly are you having trouble with? I bought it on sale aswell on my high end pc and I had trouble with stuttering altough game can run on all high settings, way I found solution is disabling low latency in your graphical control panel for game program. Play through whole game with no issue.

idk just when i do 360 it lags and stuff but i think maybe if i run these old games at a 60 fps or so might rn better? idk

late but install rivatuner and it run just fine
