fire tip downloadWhen I play Frets on Fire (I download it in my windows xp), it was very slow. Any tips to make it faster?

try going here and downloading FOFiX then you can select either the megalight or ultralight themes in the Settings menu...
hope i helped :D
The problem with it is it's very unstable fresh out of the box, check out some of the fire tip downloadmods they have for it that actually help it look and run better/smoother.

Also, if you have a playstation 3 guitar controller (with the usb plug) you can play frets on fire with that if you get sick of the keyboard controls :)

edit: Another thing I thought I would add is alot of people have crashing issues with this game, it's not really your computer's fault. And alot of people have issues with it not being in sync with the music.
