Intel 4000 isn't that bad at all. I am able to play SimCity in Boot Camp windows running at 1920x1200 with 35+ FPS. I had issues on my nVidia 330M playing at 1680x1050, got less FPS then an Intel Integrated graphics.
In low settings the HD 4000 does really quite well especially against older chips and AMD APUs because it is supported by a fast CPU. When you go to medium/high settings its performance drops realtively much more.
It still remains a very useful GPU because it is good enough where it is of any use at all. It totally fails at higher settings but even if it did as well as some APUs and not drop quite that low it would still not reach anything playable. Whether you get 15 or 7 fps doesn't really matter.
Intel delivered the most useful thing possible in that low end with little energy use and die space use.
@op This thread seems slightly pointless given that Apple handles their GPU drivers entirely independent of Windows versions. Up to 10% is also not very much given that usually AMD and Nvidia claim up to 30 or 50% at times with new drivers.
Newsworthy would be when Apple actually got around to open up quick sync so Handbrake for Mac could use it like the Windows version can.

That would work wonders and speed things up multiple times.
Apple doesn't do that though. They lack acceleration and openesss for so many more modern hardware instruction sets it is a schame. Sometimes they use it in their own products like facetime with Quicksync but don't allow any other apps to make use of it by opening the damn thing up.
Given all these complete failures in GPU driver support, I wouldn't hold my breath for a "up to 10%" driver update for Intel HD 4000.
