I have aPentium 4 3.00Ghz machine with 3 Gig of RAM and NVIDIA GeForce 6600 graphics card and the BTTF Ep1 game consistantly freezes on me after abut 5 minutes of play. I've tried a number of things from updating the graphics driver to running in windows mode to making the resolution 800x600 to setting the graphics to low. And still it freezes on me. I know it's not my PC in general, because I can run a copy of Call of Duty on it and have no problems. Any other thoughts on what I can try? I think I'm running out of options.
