What shall I do if it fails to enable GPU Accelerate?

If you have the NVIDIA® CUDA™, AMD® or Intel® Core™ graphics in your computer and you can't activate the GPU acceleration, it will generally be due to the reasons below:

1. The video card you are using is not supported by GPU acceleration. For supported graphics cards, visit this link: http://www.wondershare.com/topic/gpu-optimization.html

2. You may have an out of date graphics card driver. Visit the link for your cards manufacturer below to update to the latest version.
