I had an error pop up when the game first started, pestering me about my graphics drivers. I ignored it and played just fine while updating my drivers, optimizing my settings for my PC, and then the game started to crash during the spring sequence (mind you i figured this was because of my drivers, although i was playing fullscreen at 60FPS at this point. So i updated and installed my drivers, low and behold no crashes, but at fullscreen I was now capped at 20FPS, minimizing pulled it back up to a fluid 60FPS, and now im on the forums here. I have tried tweaking every setting available and still wont work.
