Benchmark scenes?
the simulation take long time on my machine even with very low settings.
I compare to the "FumeFX for 3ds Max Essentials Part 1 - Introduction and Overview" youtube tuto (at 3:50)
with a default grid + default simple source and my PC is 30% slower.

As the tuto is is 3 years old I was hoping to be at least a bit faster.

Is there a problem with my hardware?
Are there some benchmark scenes to check this?

My config :
Lenovo p620
AMD Ryzen Threadripper PRO 3975WX 3.50 GHz
128Go ram
2xRTX3090 GeForce RTX 3090 Gaming EPIC-X

Max2021 + FumeFx 5.12
With very simple scenes, you won't get much speedup with more cores as not all parts of the code and 100% multithreaded so there are areas where cores have to sychronise and wait for the slowest one to complete.
However, with more and more voxels the speed gain will be more noticeable.
There is also a memory bandwidth bottleneck where all cores have to read/write from the memory and there isn't many math operations between those read/writes.

Ok ...I was hoping for some hidden magical "Turbo" button I forgot to turn on Wink
Max 2021 + FumeFX 5.1.2 + RTX3090 + Redshift 3.0.30
During the simulation if you open the task manager you will notice that with smaller grid spacing total CPU utilization will climb... at least that is how it should be.
