Steam – Is it possible to run Steam games that reside on the Mac OS X partition from the Windows partition

Typically, I find cross platform games have better performance on the Windows version as opposed to the Mac versions. If you look at what Blizzard's recommended specifications are:

PC Recommended Specifications:

• Dual Core 2.4Ghz Processor
• 2 GB RAM
• 512 MB NVIDIA GeForce 8800 GTX or ATI Radeon® HD 3870 or better

Mac Recommended Specifications:

• Intel® Core 2 Duo processor
• 4 GB system RAM
• NVIDIA GeForce 9600M GT or ATI Radeon® HD 4670 or better

PCs require less powerful components than Macs do. From this, I would assume Starcraft 2 runs better on Windows than on Mac.

Unfortunately, I don't believe Steam for OS X will let you even download a Windows app you buy through Steam. I suppose you could drag and drop the game files, and then restore the game from the copied files, but I'm not sure whether that works between platforms.

And because Steam usually tries to launch all Steam games itself (at least on Windows), I don't think it would be possible to force a game to run under Wine unless Steam itself consents. You may be able to run non-DRMed games directly by double-clicking the executable, but I am unsure about this.
