The DirectX Feb 2010 end-user redistributable and SDK are out. Get the Redist. here, or if your a software developer get the SDK here. As far as I can tell there's nothing new here, graphics-wise. Just some DX Audio and XACT updates. But it's still a good idea to update your DirectX whenever new updates come out.
Just once i'd like to know what any DX update does exactly. they never say what has changed. I figured its likely developer side stuff. I'm still on last years April. never noticed, My last game install probably updated that though, still never noticed for older games.
The only games that actualy need these kinds of upates will get shipped with the appropriate DX Runtime package to ensure the new fetures the game makes use of are on the system and thus can be utilized. Other games don't need and will not benefit from the new features. Rarely, if ever, will Microsoft ship out an actual tweek, bugfix, or general performance fix this way. These updates just contain new things that a certain developer(s) might have requested or perhaps new things that the Microsoft DirectX software engineers came up with to iron out a certain wrinkle. Usually, though, these are just minor extensions or tweaks for existing technologies. Major new features will never show up in these updates. You'll have to wait for DX 12 and Windows 8 for that sort of thing. In the past, these kinds of updates have featured two different catagories of files: Either new cab files that weren't there before and don't replace old file, or (more rarely) a cab file that replaces and is a newer version of an old cab file. This Feb 2010 update is the former, not replacing old files but just adding new ones.
