I have just recently beat NV two days ago on hard, hardcoe mode. Near the end of the game, the frame rate on my 360 for this game was tremendously high.
and then after i beat the game and took it off hardcoe mode for a new game, the game was even more faster! im guessing hardcoe mode takes up even more resources then with it off.
would anyone else wanna try this out to make sure I'm not just imagining things?
tell me how it goes.

I would test this out but I can't play the game due to the DLC glitch which they are taking forever to fix.
