Yesterday I installed Borderlands 2 on my Windows 7 boot camp partition, played it for a bit (till I reached lvl 6) and stopped. When I tried it today on same settings (1680x1050, AAx4, High) performance was poor and game is unplayable. I have newest nVidia drivers. Do you have any idea why suddenly I got so poor performance? Please, help.

What laptop is this?

There are a couple potential reasons for this, and all or none may apply to you:

1. (only applies if you have rmbp)You have applied the EFI update that comes with ML which throttles GPU/CPU performance more aggressively. Only you'd know if it's been updated.

Unfortunately there is no permanent fix for this, and no way to downgrade. Some forum users have reported that a SMC reset temporarily fixes the problem. It will probably come back though.

2. The game world maps that you interact with after you reached level 6 are more complex/difficult for the GPU to render.

I have borderlands 2, and I noticed that my performance dropped a little once I actually got into the game past the tutorial area, as I encountered more enemies at once and more complex areas... these were logical drops in performance though. If you're noticing that the SAME area you were playing up til level 6 is no longer playable, then it's probably the throttling to blame.

What laptop are you playing it on? As ibebyi corectly notes, the retina MBP suffers from an SMC glitch after the recent update. I have reset it and the performance is back to normal. Borderlands 2 runs very smoothly on 1920x1200 settings, everything save AA set to max on the base retina MBP.

Sorry that I didn't mention what kind of mac I have.
I have Retina Macbook Pro so it's probably that glitch.

How do you reset it?

E: Reseted SMC and now it works super good one FullHD, thanks.

does this only work until you reboot the mac? I heard it's a temporary solution

Shut down your rMBP.

Press left Shift Button + CTRL + ALT + Power Button at the same time, wait a little bit. Done... Start the rMBP... if it doesn't work. Repeat it...
