Are you even sure you have the ATI driver loading in Windows? Something sounds like misconfiguration...
I have another problem. And it does it on EVERY need for speed game (That's all I use). After some time playing the game, the computer will just go to sleep and crash the game. Why is that?
This is a list of gaming performance for your EXACT machine:

You're thinking of the 6770m, the 6750m is a fair step down.
Neither are good cards, the 6770m is at the bottom-end of mid class GPUs.
The 6750 is a low end dedicated card and as a result won't provide very good gaming performance on medium to high settings. That said, it's not a terrible card, Apple just doesn't choose their components with gaming in mind.
To the OP: Here's a great link for deciphering the naming scheme on ATI cards http://en.wikipedia.org/wiki/AMD_Radeon
The 6770m is just a slightly over clocked 6750M.
I'm actually kind of shocked at the people dissing this graphics card. I have found it to be very good - if you know what you are doing. I do not use the stock driver that comes with Bootcamp (just awful), I tend to tweak the game, and then tweak Windows 7 for the best gaming performance.
For example, Skyrim with setting maxed runs great on my MBP.
For me, I do the following:
-Windows 7 Ultimate 64bit
-16 GB of memory
-Disable the swap file
-I use the AMD beta drivers (modded)
-I wrote a script that stops any unnecessary servers and exits any apps that are not needed.
-I rarely use the AMD OC tool.
YMMV, but I have had great success doing this.

I wouldn't necessarily say this is completely accurate for a number of reasons. I've seen a 3dmark06 score for a supposed machine like the MBP in my sig, score around 8843.4 points on average while mine scored
11467 recently. So I would say that our machines, due to the fast i7's, would run a little better than a 6750m benchmarked without giving the laptops specs.
Just install the regular ones for Windows machines.
