dgVoodoo 2

Accuracy

Performance

Features

dgVoodoo is a wrapper for old graphics APIs to run on modern Windows operating systems. Its applied using Direct3D11 with different types of wrapping outputs:

  • Hardware rendering at GPU feature level 10.1 (recommended)

  • Hardware rendering at GPU feature level 10.0 (there are some restrictions)

  • Software rendering through Microsoft WARP renderer


The API's it currently can wrap are:

  • Glide 2.11, Glide 2.45, Glide 3.1 and Glide 3.1 Napalm

  • DirectX 1-7 (all versions of DirectDraw and Direct3D up to version 7)

  • Direct3D 8.1


You also need the 3Dfx splash dlls for Glide if you want 3Dfx splash screen or watermark (shameless plug) through dgVoodoo. 


You may also need D3DRM.dll (Direct3D Retained mode) for some games and demos. It's not part of the OS since Windows Vista.
