Having just run the BMW Benchmark, I got roughly the following:

GPU: Just over 17 minutes CPU: Just over 3 minutes

Is this right? Surely not? That is a huge difference. Could it be that I have not configured things properly?

    $\begingroup$ Hello. Please change your title and question to be in line with this forum. What follows is standard in this situation. You may choose to rephrase your question to something like .... How can I make sure Blender is using my GPU? or ... Does Blender Support NVidia and Radeon equally? When you list your hardware in the title and question, it focuses on the hardware. BSE focuses on the use of the software and less so on the hardware. Most question that list hardware specs will be put on hold. Just a normal event. It happens once a week, loose estimate. $\endgroup$ Jan 25, 2016 at 22:14

  • $\begingroup$ Thank you - for the help in phrasing the question and for pointing me in the right direction. This is going to be a steep learning curve :-) $\endgroup$

  • $\begingroup$ I'm voting to close this question as off-topic because it's a hardware question, and not about using Blender. $\endgroup$
