Re: best internal format



Hi,

Just a theoretical (or quite real? :) ) question: what internal format
is the best regarding the performance? RGB(A) or BGR(a) ?

It depends; have a look at Nvidia's GPU programming guide, which tells you what formats are supported natively by which chips.

http://developer.nvidia.com/object/gpu_programming_guide.html

It's a real question if you're uploading a lot of textures (e.g. video to texture), as the driver will have to convert the texture to a native format if it isn't already in one.
