If you are a PC gamer, chances are you have already tried out the release candidate for Windows 7 or are waiting for the final release. But there may be some things that you don't know about Windows 7 that you need to be aware of before making that final upgrade. BigDownload has a few items that you may need to keep in mind:

Don't expect a lot of DirectX11 titles at first

The launch of Windows 7 also brings the launch of DirectX11, the next version of Microsoft's 3D graphics API. (Vista will also support DirectX11 but so far there's no word on when an update to the OS will happen). You can expect even more realistic looking games with more special effects to come from DirectX11 titles. However, gamers shouldn't expect DirectX11 games to be flooding the market overnight. At the moment there is only one official DirectX11 game out there; the free-to-play RTS game BattleForge (via a recent patch). More games are expected to be released in the coming months including Dirt 2 (due this December) and Aliens vs Predator (due out in the first quarter of 2010). Even if you have Windows 7 and the DirectX11 supported game you still need a DirectX11-supported video card to see the new effects. At the moment, AMD is the only manufacturer of such cards via the ATI Radeon 5800 series. Don't expect a DirectX11-supported card from its main rival Nvidia until sometime in 2010.
