It seems like opengx is better for full motion video though, I just started playing Klonoa and on newsoft the opening cutscenes were lagging. I changed it to opengx and they ran normally.
In another reply you said opengx was a speed boost because it uses the GPU to render graphics, so I guess it makes sense that for "playing videos" using the GPU would be faster. But like you said OpenGX has issues with framebuffer emulation. So isn't the play something like:
try opengx (but, if it has graphical glitches) > try newsoft (but, if it has framepacing issues or is a lightgun game) > try oldsoft
Or you could do it backwards:
try oldsoft (if it's too slow) > try newsoft (if it's too slow) > try opengx (if it's still too slow give up)
And I guess there's no reason to use anytyhing but lightrec.
