But each background tile image is 512x512 positioned next to each other in one long row and works on a range of other GPU's? I've tried it on newer ATI workstation card and it works without glitches. I guess it's just that model of card or the driver on the system is corrupt.
I wonder, is there away to detect what the GPU is in a system and deny or print a warning in the application window?
Anyway going to try it on a gforce and radeon card over the weekend which is more akin to what its targeted.
