How to Make Games Play in Dx9 on Vista Instead of Dx10
- 1). Point your web browser at the DirectX End-User Runtime installer page. Click the "Download" button and save the program file to your desktop.
- 2). Double-click the downloaded program file and follow the installation prompts. This will make sure you have all of the previous DirectX files on your PC as well as the most updated version of the current files. Reboot your PC when installation is complete.
- 3). Check your game's "Video, Graphics or Display" options pages. Publishers often will include an option hard-coded into the game that will allow you switch between graphics modes.
- 4). Change your game's shortcut. Right-click on the shortcut for your game and select "Properties." In the "Target" line, add " -dx9" (include the space but leave out the quotes) to the end of the command. Click "Ok" and double-click your game's shortcut to launch it.
