What OS is better for gaming?

Which OS is better for gaming? If you were asking about which WIndows OS is better for gaming. Then it would be Windows 7, as Windows 7 has better game support then all other Windows releases.
But, if you are asking what OS as in Linux or Windows. Then it would have to come down to Windows because it has better gaming support.

But, if you want to look at the Computer Gaming industry. Then it comes down to this.
1. being able to have their games proprietary and closed sourced. You can't do this in Linux as the Linux community requires complete open-source.
2. Being able to create a game for on Version of one OS and have it work in future versions of that OS.
3. The OS having the graphics and audio support required for the game released at that time.

I see that Linux has the potential to have great games. But, it lacks most gaming support. And gaming support that it does have is mostly through Wine to allow Windows games to run. Then there is the issue of hundreds of Linux distros out there. And because of that the gaming industry considers Linux a support nightmare.
