KAMOWhat's the difference between said "old" and "new" cfgs? I run Bootcamp on the same gen MBP under Windows and performance seems to keep getting worse even with current MaxFrames cfg in DX8. I ran DX9 Frames for a long time and prefer DX9 but as I said my rig's performance is steadily going down the tubes. Would be interested in what other MBP Bootcamp Windows 7 are using.
I'd be willing to bet that you're having the same exact issues that I was before I fixed my MBP.
MBP's come from the factory with a piss-poor application of thermal paste on the gpu and cpu cores. It's a common fact. If you want more documentation on this, simply search google using the keywords "2011 mbp thermal paste." You'll find several videos, discussions, forums etc all showing evidence of what over heating directly correlated to cpu and gpu temps.
My MBP's performance was steadily going down the tubes after a year of using it. For a while I though it was because of tf2 updates, but it was just a coincidence that the updates were happening around the time my performance was really starting to sink.
After a lot of research, trial and error, and much frustration, I finally noticed that my cpu was bottlenecking the shit out of itself every time I had tf2 running. I could alt+tab out of tf2, and my cpu's multiplier would jump back up to x31. As soon as I alt+tab back into tf2, the load of hl2.exe would force my cpu to go down to x8 to avoid overheating.
[TL;DR] This is a common issue and you have to apply a new coat of grease to your cpu and gpu core. See the thread I made a while back.

If you've never opened up your macbook pro and performed repairs like this before, feel free to add me on steam and I'll help you.
When I did this repair on my own MBP, I was nervous, as I had never done something like this on an Apple portable. With the right tools, research, patience, and caution, I fixed my MBP and made it run better than it did when it was new.
