Interesting discovery - on a slow GPU my background slows the game to a crawl. At first I used a giant sphere so the camera can move round. Then changing to a fixed camera (for play) I used just a big sprite. But it's SLOW! I guess the card can't cope with the scaling of the texture? If I eliminate the backdrop and just have black in the background it whizzes along.
So what's the problem with big polys? Why's the card so slow? Can I lock the buffer and copy over a background before rendering? Can I use a different technique for drawing the background? I used a 64x64 pixel png which is supposed to be blurred. Is larger better, and if so, why? (I'd like to unsterdand the underlying tech rather than just have a fix)
