glDrawPixels doesn''t draw geometry. Are you thinking of glDrawArrays or glDrawElements? The problem with glDrawPixels is most (but not all) consumer level video cards have it implemented poorly in their drivers. When I say poorly, I don''t mean "unusably bad", just "not so great". To get the most speed out of it, it normally helps to make sure the data is the same format as the buffer it is being written into.
