XBRZ OpenGL ES Optimizations
Hi All,

First let me say that PPSSPP is awesome and all developers involved should be really proud.

I looked at XBRZ code briefly and would like to ask about color format-related performance (mobile devices).

1. It uses RGBA 32 bit. OpenGL ES textures cannot use 32 bit, so it means you perform 2 conversions per frame - to the scaler and back from the scaler ?

2. What about games that don't need RGBA and RGB (no Alpha) is good enough ? Doesn't it perform more work than needed ?

Thanks again
