Although we’re now on Direct X 11 for Windows Vista, 7 and 8, and the next Windows will probably come with Direct X 12, Windows XP is stuck on Direct X 9 which is now over 10 years old.
Some games are not made to be backwards compatible with Direct X 9 either these days and you just can’t play the game, whether your graphics card fully supports Direct X 10 and 11 or not.
Once you have Direct X 10 on your computer and you’re trying it out, you might want to play a game that requires Direct X 9 or even earlier run.
Not all games are going to run smoothly while you have these patches installed, even if they worked fine before.
A number of stability fixes and tweaks are included as well as a fix that previously caused the installer to trigger alerts in antivirus software.The useful thing here is there’s an uninstaller in your Start menu so you can remove it if there’s instability or performance issues.There’s also a folder named “Graphic X” in the archive that contains a number of individual tweaks and fixes for specific games and options to edit the Direct X version via the registry.Like the previous package, this is another standalone executable and everything is self contained inside the installer.During install it actually gives you the choice of selecting one of three different Direct X 10 versions; Alky Project, KM-Software’s own version and Zlocorp.
