Not sure if this sure go here or somewhere else. If this is the wrong place, can it be move? I'm currently playing Kingdom hearts 2 final mix on an emulator, And it's lagging to the point where gameplay is in slow motion and everyone sounds like a robot. What can i do to reduce lag?
Unfortunately, not much. Assuming this is PCSX2 If you enter Config > Emulation Settings > Speedhacks you can get back some of the FPS. And I would enter the plug in settings and make sure everything is very basic, native resolution, linear scaled audio, etc. But ultimately I very much doubt that you will be playing it full speed.
I did all the stuff you said, and it still lags a little bit from time to time but it's much better. Thank you :)
