Hi, at some point I want to upgrade to the Threadripper 7980x with 64c and 128t, I wanted to know if Tyflow would really take advantage of all the threads like vray does, this processor is 4 times faster in vray than Intel 13900K, can we achieve same ratio on Tyflow?

tyFlow PRO will use as many threads as your system has, however the speedup won't typically be linear because eventually the computations will become memory-bound rather than CPU-bound. The speed also depends on other factors, like core type (performance vs efficient cores in Intel CPUs), etc.
On my 13900K I get a pretty linear speedup until about 14-16 cores, after which the benefits drop off in terms of performance increase.
Also tyFlow does a lot of load balancing internally, so not every multi-threaded function will use all cores just because it may be more efficient to use less, depending on function complexity and particle count.
I’ve been eyeing the Threadripper 7980X too—it’s seriously powerful. In my experience, Tyflow can utilize a lot of those threads, especially for complex simulations. I noticed a solid performance increase when I upgraded my setup, but it’s not always a perfect 1:1 with V-Ray. Still, for heavy particle effects, it definitely speeds things up.
