Hello,
This is my first post in this forum and I hope I get a solution to my issue. I’m currently evaluating Deadline 10 with two machines, one running Centos 7.6 and the other is running Windows 10. I’m using RedShift 3.0.16 version licensed on both machines.
When I create a 3D Redshift job using Deadline Monitor from the Centos machine using both machines to render, everything goes well and both start rendering using Redshift commandline with no errors. However, I notice that the Centos machine renders three to four times faster than the Windows machine.
Checking the logs on both PCs, I found this to be the issue (there is more than five minutes it took to create the tree on Windows):

However, both rendered, but still on the Windows machine it was really slow as shown below (sample):

Note that both machines have dual 2080TI GPUs each.
Any advise on what would be the cause of this?
Thanks…
