Yes I downloaded NV to my HDD and cleared my cache to stop the freezing issues I was experiencing. Well, needless to say, I am still having the same problems. I don't have the save corruption issues that everyone else is. My game just freezes every few minutes and I have to do a hard reboot and reload and try again.
I installed it to my HD, which I do with all my games... and clear the cache using the "A" button method... and have come across the occasional minor bug.
If I think the game is becoming unstable or load times are taking too long, I reboot, clear the cache again, and pick up where I left off.
