ABSTRACT:
A system and method for optimizing the performance of a graphics intensive software program for graphics acceleration hardware. This system and method encompasses a procedure that validates the different functions of a 3D acceleration capable video card, decides whether to use the acceleration hardware and optimizes the software application to selectively use the functions that work on the specific video acceleration card. Functions checked include sub-pixel positioning, opacity, color replacement and fog. If these tests are successful, then the graphics acceleration is used by the software application. However, if the tests are not successful the decision is made not to use graphics accelerator. Those with ordinary skill in the art will realize that it is not necessary to perform all of the tests in a specific order. Additionally, other types of tests could be performed to ensure software application and video card compatibility before the software application is uses graphics acceleration to render 3D graphics.
