Buffered vs. Non-Buffered Rendering

[mupralsh]

Yeah just like Razorback said, buffered rendering makes the emu does stuff more accurately like the real PSP, so you can see the glowing and other effects. Non-buffered rendering in fact, is also called 'speed hack' simply because it enables the emu to run faster in exchange of some missing graphical effects (including HUD in your case), I don't know the technical explanation though, but that's why you encounter that problem in the first place.
