Crazy FPS with new machine

Recommended Posts

Hi everyone, 
I'm a creative director of boutique CGI studio specialised in animation and visualisation for branding and packaging. 

I decided to expand our work toward motion and FX and thought of X-Particles as perfect addition. I'm currently trial the software with great chance to buy and incorporate in our workflow. 

However since first testing, on a really basic scene (xp system with single emitter, xp domain and gravity, simple as that) we experiencing a really slow FPS, around 5-10FPS. Which for these extremely starting scene is no-workable at all. Looking at some video online on similar starting scene the viewport speed is more than double. 

Current setup is a new Mac Pro 2019, with 28core, Vega Pro II Duo module and 96GB RAM. On the latest Catalina 10.15.5 and C4D R21. 
A very powerful machine but I'm wondering if it is something software related and you can help me with, or embedded problem and related to the OSX, etc. 


Indeed I don’t seek for hardware debate, decision, etc.  But if it is something related to X-particles / C4D specific setting, or other issue/process that runs on background and makes the simulation really slow. Or any specific hardware compatibly issue.
Having seen same starting scene setup on a window machine with way less specs but much higher FPS, I was wondering if we made a bad decision getting the new Mac Pro or there's some hidden issue/thing to be fixed around software and parameters to run it better.
Or, sadly, worth sell back and buy a windows machine instead, something like “hey, this performs worse on OSX so nothing to be done”, and we need to embrace and work around it as it is. I'm used to the OSX system and mainly got the studio based on it, so ideally I'd avoid this as much as possible.

Would be extremely helpful if you can help me out with this. 
I've included a screen record and screenshot of what happening here https://www.dropbox.com/sh/qi2khodotd69s2u/AAALDBPHGODmIMJFGTvTPgF8a?dl=0 


PLESE NOTE: this also happen with any simply soft body sim, etc. No really strictly to X-Particles I guess.


Thanks a lot to everyone

Many things in C4D are still single threaded, including dynamics, simulations, particles and similar, you need high clock IPC cpu (4+ GHz), like latest Intel i7/i9  or AMD Ryzen 3XXX series, in order to get higher viewport fps performance. That Xeon is good for rendering, but for things like dynamics, simulations and similar you need high IPC cpu.

What's been said above, IPC (Instructions Per Cycle) and Ghz, you want the best of both worlds, until software developers move from single threading to Multi-Threading (alongside GPU acceleration), the 28 cores Xeon in there runs at a base clock of 2.5 Ghz and go up to 4.4 (on a single core) for a short period of time before going down and stabilizing on a much reasonable Ghz for longer periods.

for a similar core count (24 and 32) from Threadripper 3960X and 3970X respectively they run at a base clock of 3.8 Ghz and 3.7 Ghz and can go up to 4.5 Ghz.


I will put this here and see myself out.
