dgVoodoo is a legacy DirectX and 3DFX Glide wrapper program. The purpose of this software is to translate or wrap function calls to old, legacy graphics API (application programming interface) functions into calls to the much more modern Direct3D 11. In other words, it acts as a translator, changing old games to run with newer, modern graphics techniques. Using the wrapper is very easy, and you can try it with any game that uses DirectX or Direct Draw versions 1 to 8, or any game that uses 3DFX/Glide. Of course, since this software uses Direct3D 11, you will need a graphics card or chip capable of using this version of DirectX.
To get started, download the latest version from the gdVoodoo homepage here. At the time of writing, the latest version was v2.43. The file is downloaded as a zip file, once downloading is complete, open the zip file in file explorer. You should see the following folders.
If you’re trying dgVoodoo with a DirectX game, then you should open the “MS” sub folder and copy all the contents to your games installation directory. If you’re trying a 3DFX/Glide game, then copy all the files from the 3DFX folder instead. Do NOT under any circumstances copy the dll files inside the MS folder to your PCs system directories (anywhere within the Windows folder).
Finally, copy the dgVoodooSetup.exe file into your games installation folder too. This makes it easier to configure dgVoodoo for your specific game.
As long as you copied the .dll files to your games installation folder correctly, all that you need to do to run the game in dgVoodoo mode is to simply start it. Of course, not every game is compatible, so it’s usually just a matter of trying the game out and seeing if it works. To remove dgVoodoo from a game, just delete the .dll files you copied in.
You can configure dgVoodoo by running the dgVoodooSetup.exe program from within your games installation folder. Technically this program doesn’t need to be in your games installation folder, but it is the easiest way to use it. Run the program and the following window will appear.
Before you get started, click on the button circled in red in the picture above. This makes sure the configuration file is written to the correct folder.
The options that you configure are generally set on a per-game basis and may need some experimentation. There is one important option you may wish to change for every game however. Over on the DirectX tab there’s the option “dgVoodoo Watermark”. This applies a watermark to the games graphics in the bottom right hand corner of the screen. While you are configuring dgVoodoo we recommend leaving this option on, as it is a good indicator that the wrapper is working correctly. Once you are happy that everything is configured and working, you can then disable the watermark and play your game.
Since dgVoodoo makes old games use newer versions of DirectX, it can also enable compatibility with certain in-game tools and utilities. For instance, when a game is running through the dgVoodoo wrapper, it becomes compatible with the Nvidia Shadowplay screen recording software and the excellent in-game overlay Evolve.
