I'm fairly new to Fallout so I picked up GoTY a few weeks ago. So far I have completed the game up to the beginning of the broken steel addon (finished normal game), so my file size is fairly big. Today I started OA and I've encountered some pretty heavy lag after you blow up the artillery things. So I deleted the game data, started it up again, and the game ran much smoother. However, right when I finish planting the charges at the chimera depot, and sgt. montgomery says he's bring the squad back to the hq, my game keeps freezing at the load screen. It's froze twice in a row now and it's starting to piss me off. Any suggestions?
