Use shader is too bad for AMD GPU

What is your graphics card? My graphics card is ATI Radeon HD 4200, so I'm not too sure if updating the drivers for my graphics card would even make a difference (currently using 12.6 Legacy Driver). The only options I have when it comes to updating is using either 13.1, 13.4, 13.9, or a modded Legacy Driver.

Actually, the one who use AMD GPU are my friends, we want to play mhp3 Multiplayer in hamaci network. but JPCSP run too slow , Finally, they Install 13.1 or 13.2 Driver. it make JPCSP run faster. you can try it if you want.
