FumeFx CPU usage problem

[Kentan1119]

Hi,

I have recently moved from my old i7 2700k machine to dual xeon e5 2650v3 workstation.
I had hoped that I would see the increase in FumeFx simulation times. However for some reason fumefx is not able to utilize all cores to the maximum. The cpu usage peaks at about 20-30 percent during fumefx simulation....which actually makes it slower than my old i7 machine. I have cinebench cpu score of 2350points. For rendering I use Vray which has no problem of utilizing all 40 threats at 100percent. This problem purely happens with fumefx simulations.I use 3dsmax 2016 and fumefx v4. something. Is it possible that fumefx for some reason is not programmed for so many threats?

The answer I got from SitniSati was

Hello,

We have dual Xeons HP Z820 and have not seen any issue using FumeFX 4.



My pc specs.

Asus Z10pe-D8 WS MObo.
Xeon e5 2650v3 ES dual
8x8 ECC Kingston 2133 RAM
GTX Titan 6GB
2x 256GB SSD
1x 2TB HDD

Did you setup FumeFx to use all the cores and cpu's?

Yes..I did try every option that Fumefx provides with regard to performace... there isnt that many to start with. You can just choose the number of cores used. I have even tried to turn off hyperthreating in BIOS and play with affinity inside tskmngr but with no results.
