Xposted with you, ynsaen... Not picking on you, Khai. But I spent some time playing around with the Crystal Space open source game engine, when they were trying to hammer out the OpenGL issues that were vital to its cross platform nature. It was a nightmare, and a couple of coders said to hell with it. They finally scrapped all they had and started over, and it works now, but there are still a lot of issues. And this is code that is designed to use a game card for what it was meant to be used for.
