Main computer for photography has a quadro M2000 4Gb graphics card. When performing AI nonoise/tak sharp the rendering is a little slow. In addition once this process it performed any subsequent return to the image is slow to render. I decided to try to determine if a GTX 660 would give better performance. The GTX is in a different pc but both run on windows 10. The GTX pc turned out to be infinitely slower. On investigation I discovered that the GTX machine was using the cpu and not the gpu to render although the system preferences were identical. Both systems were using about 1Gb of gpu ram. I tried to force the GTX pc to use the gpu by changing the preference from auto to the GTX graphics card but it made no difference the system used 60% cpu and 2% graphics. The quadro uses 100% gpu and 2% cpu.
Has anyone a solution for the GTX gpu not being used?
In addition what graphics card would be a better fit as the quadro is bottlenecking the rendering?
