Ability to use more than 64 threads

[Mokiki]

Wish I'd have seen this thread sooner. I think today our new 72thread machines should arrive... Well here is hoping. I thought vray supports more than 64+ threads out of the box since 3.3. At least that was the last info I had from Vlado.

Hello,

To support more than 64 threads V-Ray 3.3 required an environment variable - VRAY_USE_THREAD_AFFINITY=1
In 3.40 and later it is ON by default.

If V-Ray 3.4 and later is not using all the available cores - it would be best to contact our support - they can help with that issue.

Best regards,
Yavor

One of my clients has issue when rendering on 72 logical cores machine - it is rendering only with 32 logical cores. It is dual xeon machine.
As i understand that is related to this problem ? Does VRay 3.5 solve this issue?

What Yavor replied. We have an 88 core machine here and it works fine with V-Ray 3.4 and 3.5 by default.

Best regards,
Vlado
