Not sure whats wrong with ati/amd , but it looks like alot of opengl programs (even outside jpcsp) has problems with these cards, from reading other peoples posts it seems like some drivers work better then others.

you could try lwjgl 2.8.0 that was just released looks like it might have some amd fixes, just replace the matching jpcsp libs & dlls with the ones from lwjgl

I doubt it will make much difference though.
