Best configuration for ARX Photolux (wildfire 5)

Hello everybody,

I am looking for the best configuration for my computer to increase my photolux arx application on my Pro/E wildfire 5. My goal is to accelerate computation time, I'd like to know if I must give priority to processor or graphic card ?

Intuitively, I think during a photolux computation, computer uses processor rather than graphic card. Graphic card is usually used during realtime 3D, is that right ?

Last questions, do you know if ARX photolux can use Hyper-threading, and can you advice me configuration (processor,etc...) ?

Many thanks !
