| 5 | 5 | ## Introduction
|
| 6 | 6 | DXGL is a free replacement for the Windows ddraw.dll library, running on OpenGL. It is designed to overcome driver bugs, particularly in Windows Vista and newer operating systems. It also adds various enhancements to the graphics output such as display scaling and filtering options. DXGL supports the DirectX 7.0 graphics APIs, however it is currently under development and many programs are not yet compatible with DXGL.

| 11 | 11 | If you wish to migrate any old profiles generated after installing DXGL 0.5.9 or later, you will need to use Regedit to delete the "Configuration Version" registry value from the HKEY_CURRENT_USER\SOFTWARE\DXGL registry key to force the upgrade to be run again.
