Re: GPU card

We’ll soon see GPUs from Intel. Use of CUDA for FFT isn’t too important, good DirectX really makes the performance of Console smooth on one or more 4k monitors. Anyway, the GTX 645 is quite respectable when it comes to DirectX but any newer card will be better and use less power. And a newer card (if you can get one) can later be used in a new PC.
My gut feeling is that the GPU is not the cause of the problem. Please show this task manager page and make sure the CPU is visible (it may not be shown):

This is a follow up to my previous "Minimizing CPU load" topic. In retrospect it's not the CPU load that's my issue, but SDR-C's effect on other logging applications. My CPU load is around 8% +/-. My machine is a Dell Optiplex 9020. It has a i7-4770 quad core 3.40 GHz w/ 16 GB RAM. I could upgrade to 32 GB.
