I agree with most of what DJBMASTER says, would'nt dare anything else being a Bruce Lee fan too. However, I did try to push the GS system and was able to load a 8192x8192 terrain map on an unchunked 129x129 vertices terrain. It took a while to load, less than a minute though. Didn't try larger texture than that. I used a nvidia card with 128 meg, so it probably used a bit of virtual memory too. Not sure if it is really usable in a game at this point with currently available hardware. Just say that I loaded it and moved around the terrain a bit without problems.

cheers,
