PPSSPP causes performance issues

[JohnnyTheWolf]

The broken port has already been taken care of, in the sense that it did cause a short a while back and I since had it removed, as replacing it would have been a costlier operation: I now only use the remaining front USB port to connect my PSP to the computer. I do own a surge protector and I also regularly clean out my computer with a compressed air canister. I will check for wires, though.

As for PPSSPP itself, yesterday, I played a game with the keyboard for a while and I did not notice any problem. I will continue troubleshooting, but it really looks like the Xbox 360 controller connected on the back of my computer right next to the mouse and keyboard is the cuplrit.

Thanks for the advices!
