There are two issues I identified. One is the glDrawPixels/Texture rendering problem already discussed in another thread. Another is that ATI card (at least on my mobility radeon x1300) has bad support for non-square texture size (256x192). Even if I fixed the texture to be square, on my ATI card glDrawPixels is still faster than texture loading, maybe it is implemented as a seperate optimized 2D rendering path.
