I have been playing NV since launch. The framerate has been absolute garbage but some of the fixes I found make it a bearable 20-30 FPS. But thats not the point for some reason it just started crashing right after the copyright stuff pops up. It has never done this and i haven't changed ANYTHING since it was last working. I played all day, put my computer to sleep, then i woke it up clicked on NV and boom crash.

if it helps this is the error report
