I enabled openCL, and it still didn't read anything. And I usually start it by right clicking and selecting, "Run with graphics processor > High-performance NVIDIA processor (Default)" Neither of these actions made it read any activity. I'm so confused.. It works like a charm on any normal PC game, and even on Project64. I'm going to give 4.0- 539 a whirl. I might not have access to reliable internet for a while over the holidays, though. Thanks for the help.
