DXGL is currently a work-in-progress and is currently considered alpha-quality software..

See DXGL Features for detailed information.

See Version history from the downloads section for release information and previous version downloads.

Also see DXGL Test Results.

What works:

  • DirectDraw object creation and destruction (versions 1 to 7)
  • Display mode enumeration and switching (with emulated mode switching)
  • Fullscreen and windowed modes.
  • Basic Blt() functionality
  • 8-bit color emulated with GLSL shader

What partially works:

  • 3D graphics are only partially supported.

What doesn't work:

  • Many functions are stubbed out and return an error
