Difference Between DX9 and OpenGl

[LunaMoo]

Actually on the performance topic, as an AMD user I just tested both in few games, without shaders since d3d doesn't have them and I would say OGL is usually a few times faster than d3d for me when very high res is used, so maybe other people just forgot to turn off shaders hence OGL was slower for them, or my gpu just has a lucky drivers(it's pretty old from hd5000 series, but still getting driver updates;3).

PPSSPP is pretty light anyway, so it doesn't really matter for me, but worth mention it's quite likely the first windows app using this backend which I don't have problems with. Not sure, if it's because drivers improved alot recently or simply ppsspp is much better coded than commercial products/games using OGL on windows which terrorized me in the past.;]
