Hello guys,
I have a CPU utilization problem! Threadripper build specs as follows:
X399 AORUS XTREME TR4
Threadripper 2990WX
GeForce 2080 Ti
128GB Kit (8 x 16GB) HyperX Predator DDR4 3000MHz, CL15
PRIME Ultra Gold, 80 PLUS 1000W PSU
Dark Rock Pro TR4 CPU Cooler
The system is running very well, temperatures are good, but I recently noticed slower than expected performance when calculating GI for several animation sequences. I tested this against my i97980XE system which was indeed much faster. I then noticed that the 2990WX system was only utilizing between 38-40% of the CPU during the pre-calc GI phase whilst my i9 was utilizing 100%. Virtulization is enabled on both, for what that is worth.
The RAM in the 2990WX is set to 3000mhz in the bios. I've tried setting it to 2933 and some of the different built in profiles but there is no change. I'm running the latest Corona 5 with 3ds Max 2018.
Here is strange thing: once the GI has been calculated and the rendering begins, CPU utilization jumps right up to 100% and stays there. This must be a clue..?
Does anyone know what this could be? As it stands, this system (purchased specifically for rendering animations) is currently slower than my older i9. I'm in a bit of a bind here with a large deadline looming.
Thanks so much for any help!
