    Utilizing multiple graphics cards in UE4?

    Hi Epic,

    I'm one of those people who has multiple graphics cards in their workstation. I actually have a NVIDIA GTX Titan (on a primary display), and an AMD R9 280x for auxiliary use.

    I originally got one of each "kind" to cover both CUDA and OpenCL requirements of some applications, but now this got me thinking if these cards could be further used inside UE4.

    I know that NVIDIA cards are already being used for PhysX and APEX, but I thought isn't there some other task that could employ OpenCL as well, or further utilize CUDA capabilities?

    I saw someone posted that it took them over 4 hours to package an Android project - could we not use GPGPU to accelerate texture conversion/compression for example, or some other computationally demanding process?

    Thanks.
