FusionWorks Renderer significantly increases render time on AMD Threadripper CPUs - Vipera - 02-08-2020
I have found that FusionWorks Renderer significantly increases render time on AMD Threadripper CPUs to compare to Intel i7 CPUs. I started to complain on ChaosGroup forum thinking that my new AMD Ryzen Threadripper 3960X CPU has long render time because of some of the V-Ray settings. But after I shared the scene file for the test with other people and checking their render time I was able to nail down the problem. And problem is FusionWorks Renderer.
Here is the test Max2018 file with V-Ray 3.60:

FusionWorks Renderer
ON
i7-6950X render time: 2m 51s
Ryzen 3960X render time: 5m 51s
OFF
i7-6950X render time: 1m 53s
Ryzen 3960X render time: 1m 11s
As you can see, when FusionWorks is enabled Ryzen 3960X 24-core CPU is slower than i7-6950X 10-core CPU. When FusionWorks Renderer is enabled it slows down render on i7 as well but not so critical as on Ryzen computer. I recently wrote on this forum that Afterburn has 32-core limit and crashes when it tries to use more cores. I thought that FumeFX doesn't have this problem but looks like there is a similar issue.

Hello,
The AfterBurn bug is solved and we're looking for this particular issue with VRay.
Thank you.

Ok, I will come back to check the status 3 months later. Thanks!

I am sorry to say but I had to switch to Phoenix FD plugin because of lack of support from FumeFX team.
