When working correctly, the FAHClient detects GPUs when their driver is installed. An AMD GPU requires the AMD drivers, an nV GPU requires the nV drivers and the Intel GPUs are not supported (yet).
You are NOT required to have a nVidia GPU ... or any GPU, for that matter. The FAHClient always looks for supported GPUs (with drivers) for all three brands. The message that CUDA was not found does NOT indicate an error; it simply indicates that the hardware and the driver code are not present -- which SHOULD always be true if you do have not properly installed an nVidia GPU with it's drivers.
