Q: 

Uploading full screen texture every frame in OpenGL on iPad

I'm trying to port some old game code of mine and what I have is a 1024x768 array of pixels.

I created an CADisplayLink and each frame I glTexImage2D() the entire thing.

This causes a problem: cpu-side twiddling. Seems that iPad makes 32x32 twiddling in realtime, before uploading the texture.

Can this be avoided? I must keep my pixel bytes linear, I can't rearrange them.

Cheers!
