adamchina Posted June 30, 2015 Share Posted June 30, 2015 Vray says 6 (6 buckets) Task manager says 6 cores Device manager says 12. I have 2x hexcore intel X5690's in the computer so I'm inclined to believe the device manager. If my suspicions are correct I can't believe Vray has been using just half my cpu power all this time!! Will it literally have been rendering at half of potential speed? Could anyone shed some light on this for me and how I might configure Vray to read all 12 cpu's?

numerobis Posted June 30, 2015 Share Posted June 30, 2015 (edited) The taskmanager shows that only 1 CPU is recognized and only 6 Threads. Are you running Win 8 or Win 8 Pro? You need Win 8 Pro for 2 CPU systems. Is hyperthreading enabled? Edited June 30, 2015 by numerobis Link to comment Share on other sites More sharing options...
adamchina Posted June 30, 2015 Author Share Posted June 30, 2015 (edited) Thanks for getting back to me! I'm using Win 8.1, not pro version. However I just enabled hyperthreading and Vray now shows 12 buckets, which is great although my computer seems to have slowed down a little. I guess this means each of the six cores in the one identified CPU is now capable of being provided by both its threads? Meaning I am now optimising the use of 1 CPU but the other CPU cannot be included due to the Win version? Correct? So it seems a Vray bucket represents a thread and not a core? Is this true? Given my specs should I therefore have 24 threads = 24 Vray buckets? If so, does this mean I've been using just a quarter of my computers rendering power??? Thanks a lot!

Yes, as i said above, you need at least the Pro version for two CPUs. Bucket=Thread; 1CPU= 6cores/12threads; 2CPUs= x2 Hyperthreading adds maybe 25% depending on the software.

adamchina Posted July 3, 2015 Author Share Posted July 3, 2015 Great thanks, I believe windows 10 comes out this month, I guess I'll just get that and should be good to go. Adam Link to comment Share on other sites More sharing options...
