Hey everyone:
I've just recently purchased VRay and I'm waiting for my permissions to come through to post in the private sections of this forum.
In the meantime, I figured I'd post up about my issue and see if anyone has a solution.
What's happening is that when I start rendering, my CPU is throttling up to 100% but then probably 75% of the time it will drop back down almost instantly. When I watch my Task Manager I can tell what's happening. Essentially, VRay isn't utilizing all of the RAM that my system has available and it starts using my disk, which slows everything down. The solution has been to go into Render Setup -> Settings -> System and mess around there by changing the Dynamic Memory Limit and clicking Embree off and back on again.
Eventually, this will work and VRay will use all of the RAM that it needs to keep my CPU at 100% throughout the render (I have 64 GB and I've never gotten about the 50% mark while rendering). The confusing part is that I can finish that rendering, click render on a new one in the same file without changing any settings, and it will throttle down again as it did before. The only solution is, again, to fiddle with the Dynamic Memory and restart the render a few times until it works.
I've tried setting the limit to 0 so that it uses what it needs and I've also tried setting it very high (48000, 50000, or 64000) and none of them work consistently. Any ideas as to what the problem is?
Thanks in advance for any help you can offer!
