No. When we feel OpenGL is fixed enough to be put back in, we will put it back in.
Furyhunter said:SRB2 uses multithreading but is not designed with multiple cores in mind. Vista onward will automatically put the main thread on the core with the least current load on it, but not all threads (like setting the affinity will do).
OpenGL is kind of fixed right now. It's so horrifyingly broken and crashes when you do pretty much anything, but it starts up as of 2.0.2.
