Ahh, thanks cbmeeks. I see you're well into your tilemap routines and have looked at several alternatives. What do you reckon's the favourite for speed? I haven't tried cache map or a 3D based tile engine yet.
I made a little game with a full screen of 32*32 tiles. Runs fine in 1024 by 768 on my P3 1GHz, but is unplayable at 1600 by 1200. My brother just got a top end P4 with the latest GForce card (I have GForce2), and I was really disappointed to see that it didn't really run any better. I know 2D is not being developed much on new cards, but I would expect it to be getting faster just for the fact the newer cards run at higher clock rates.
