GPU usage

[tyoda]

Understood Keyshot will max CPU cores when in operation, but I understand GPU capability is now part of 2.1. 

Question- does Keyshot also max the GPU, all the time? 
Does it discern whether the computer has a discrete GPU card or integrated?
Is it only compatible with certain GPU cards?

We only use the GPU to do some post processing. Currently we have bloom and vignetting effects. This only uses a small percentage of the GPU and you don't need any specific type of graphics card. Integrated graphics works just fine.
