Currently, OpenGL doesn’t contain a switch to enable or disable hardware acceleration. Some vendors might provide this capability with an environment variable or software switch. If you install your graphics card, but don’t see hardware accelerated rendering check for the following: • Did you install the device driver / OpenGL Installable Client Driver (ICD)? (How do I do that?) • Is your desktop in a supported color depth? (Usually 16- and 32-bit color are accelerated. See your device vendor for details.) • Did your application select an accelerated pixel format? You might also have acceleration problems if you’re trying to set up a multimonitor configuration. Hardware accelerated rendering might not be supported on all (or any) devices in this configuration. To force software rendering from your application, choose a pixel format that is not hardware accelerated. To do this, you can not use ChoosePixelFormat(), which always selects a hardware accelerated pixel format when one is avai
