Instructions on selecting configuration for 3d CLO installation
Hi 3D Clo,
I have plans to build a computer that is configured as the I7 10700 CPU, 32GB RAM and I intend to choose 2 video cards that are VGA 3080TI and VGA 3060TI. I am considering choosing 2 video cards for GPU support for 3D Clo to minimize the CPU Supporting process that always accounts for 100% Task Manager. Please advise me on this configuration? Is NVIDIA card suitable? Which card should I choose in these 2 cards, do I need to upgrade? What about the CPU?

GPU simulation is NOT recommended for the final beauty pass simulation in the workflow (see the manual for this statement). Therefore you will see little to no benefit by having 2 graphics card for the cloth simulation as you can simply dial up the mesh particle distance when drafting in 2D and sewing during work in progress. Where your high quality simulation is concerned you need to have a high CPU clock speed > 4+Ghz is best.
If you are going for a turbo charged CPU that idles at a low Ghz clock rate it will mean the CPU fan will kick in when the turbo cooling on the CPU kicks in to ramp up the clock speed to higher rates eg: >over 4+ Ghz. This means your workstation can get noisy when simulations are constantly drawing on that CPU turbo resource with it's fan. So review your latent CPU clock speed.
I run a special chilled CPU that has a very high tech superconducting material sandwiched onto the CPU to heat exchange so the chip can run hotter and higher Ghz than specified. This also means the CPU can crash on high demand - so that is a potential outcome for the hunt of high Ghz.Best to go for reliability in CPU clock speed - the many new turbo CPu's on the market are excellent performers for cloth simulation done in bursts. So you should be fine with a turbo CPU ,.... unless you are going to run animation sims 24/7 .... then you might want to think carefully about heat dissipation .... especially like me here where temperatures in summer can hit over 40 C regularly. So then cooling becomes an issue in a cabinet space.
The vray standalone rendering engine is also different from the CPU and GPU (See article) so once again you need to be careful what benefit you are going to get overall from more GPU's verse better CPU's.
For me the king performance with MD/CLO3D is the CPU and it's highest possible clock speed in Ghz. That will NEVER change as the maths for cloth collision is going to be best on the CPU into the future .... so think carefully about what other tasks your workstation needs to do in conjunction with CLO3D eg: photoshop, texturing, materials development in rendering, modelling surfaces externally, substance painter, animation etc etc . These apps may rely more heavily on GPU resources with many apps open, where RAM, Solid state Hard disks, Video VRAM for scene size, and overall work loading performance need to be balanced out as you work across two/three screens. That will likely have more bearing on your best workstation hardware combination. As far as MD/CLO3D goes you will get best performance from a good GPU card with a lighting fast (fps) simulation cycle in quality mode on the CPU. Which means unlike rendering workstations you need to care more about your CPU specification than you might think when dealing with cloth simulation.
Time to revisit your specification before you spend money. And think about the overall work combination your workstation will need to do when making samples - it is not generally done in isolation so dig deep on what other tasks that surround your workflow need to be factored in and choose your GPU's based on those drivers all in concert with each other.
If in doubt ask CLO3D support about the hardware choices and also check out their recommended specification pages.
