ATI / AMD cards currently have poor or buggy opengl support and usually the user needs to try various drivers just to find one that works. for directx games they are probably on par with nvidia cards.
Jpcsp uses OpenGL, so unless amd fixes their drivers their cards will continue to have poor support in many opengl applications including jpcsp. also most of the devs and testers have nvidia cards so most optimization go towards that.
The most common issue with ati cards and jpcsp is very slow speed and no shader support (depending on the driver used) and other strange bugs.
