Selecting Graphics Card

[AlanMc]

Dear All,

My workstation has two graphics cards. My primary is an FX1800 and only runs OpenCL 1.0. So no good for GPU simulations. My other card is an GTX 670 4GB card that does run OpenCL 1.1 and Compute Capability 2.0. So is good for GPU simulation. The FX1800 is used to run both my monitors leaving the GTX card for simulations and GPU rendering.

I make the necessary change in the Hybrido simulation options to use GPU sim, but Realflow 2013 crashes (shuts down). Just before the software stops I can see that it is accessing the FX1800. How do I get it to select the GTX card instead?

Many Thanks,

Alan
