Hollywood FX uses OpenGL, which is the industry standard 3D graphics language for high performance high quality rendering. Over the past few years the 3D accelerators and their OpenGL graphics drivers have improved dramatically, however there are still times that the graphics drivers cause incompatibilities with Hollywood FX. For this reason, Hollywood FX defaults to software-only rendering for the highest degree of compatibility, at the cost of slower previews and rendering.

The topics below describe the steps you can take to improve 3D rendering performance. You should only try these changes once you are familiar with Hollywood FX and have successfully rendered some effects in your projects.

ð CPU speed, bus speed and memory

ð Graphics card drivers

ð Adjusting preview rendering performance
