Just to chime in here, you guys are a little misinformed. I play on PS3 and the only time I've ever had crashing problems is in Bitter Springs, McCarran, Forlorn Hope, Red Rock, and The Strip, which are problematic across the board. Other than that. In the year or two I've been playing New Vegas the only time I've had real trouble play wise is if I've played for consecutive 5-6 hours relentlessly.
Same here. I can play New Vegas and Skyrim and the only time I run into problems, with either of them, is when I have been playing for 4-5 hours straight.
