I''m pretty new to opengl. I''m working on an app which needs to fill a large (900*900 pixel) moving background image with a pixmap at atleast 30 fps... Right now, I''m getting abysmal performance. What''s the fastest way of moving the image from the processor memory to the framebuffer? Simple glDrawPixels() calls don''t seem to give me enough performance. As far as I can see, the memory transfers aren''t large enough to be a problem... any idea where the bottleneck might be?
I''d appreciate any help.
