As DUGL is mainly for games, performance is the highest priority. Plain RGBA will need twice memory bandwidth as 16bpp with a little improvement in quality.
Same, using RGB (24bits) will make pixels not memory aligned which is very bad for performance.
My estimation for example for your i7 as you reached 250 fps (about 0.5G texel/s), with RGBA you will never cross 150fps, which isn't small loss.
Anyway I agreee that supporting RGBA will make DUGL more generic for any usage, like making paint, video editing or any application requiring high definition colors.

Ok let's hope that a developer will port again the last FFMPEG for DOS, it will be nice if it's mmx optimized to get more performance.
