Wars Knights of the Old Republic II: The Sith Lords
What is the importance of OpenGL compatibility?
To run Star Wars Knights of the Old Republic II: The Sith Lords, your video card driver must be using OpenGL 1.4 compatible software. OpenGL is a graphics API (Application Programming Interface) that was originally developed for professional workstations. It is now a standard API for 3D hardware acceleration, utilized in several current 3D games for the PC.
NOTE: For optimal OpenGL compatibility, make sure that you have the latest video drivers for your graphics card available from your hardware manufacturer.
