Hmm, so using higher graphics settings made it play smoother?
D3D9 is the subpar rendering engine (because it doesn't support a couple things like dual source alpha, which we need to emulate PSP oddities correctly), generally, unless you're using a graphics card that doesn't like OpenGL. You'll get less graphical glitches using OpenGL so prefer that if the speed is roughly the same.
