Graphic cards performances in ContextCapture goes as below:

• 2 GPU: 15% faster than 1 GPU
• 3 GPUs: 20% faster than 1 GPU
• 4 GPUs: 24% faster than 1 GPU

User should know that:

1) The benefit of adding additional graphics cards beyond 2 does not double the performance with each one.

2) User may benefit more by installing 2 graphics cards in each systems, installing multiple CC Engines and clustering (ContextCapture Center).
