Dynamic Simulations Kill MY Computer

[Rough1]

Hello,
I'm having a really really frustrating time with simulations.
I use cinema 4d mostly for modelling and technical instruction animations, and don't have all that much use for dynamic simulations. BUT, the odd times that I do need it, I find it impossible to work with. The most seemingly simple things that the tutorials on YouTube show that will play in nearly real time for them ( Rope, connector, balloon, gravity, turbulence etc etc) shuts my computer down instantaneously. Even in the simplest scene.
My workstation is a couple of years old, but pretty well stocked with a Intel i9-9900K CPU 3.60 GHz, 64 gigs ram and 2 RTX A4000 cards.
After setting a simulation, I push play, only to have the thing freeze for 4 minutes then proceed to go 1 frame every 30 seconds or something. I cant stop it, I cant click anything and then I have to crash it with the task manager.
Very frustrating. Is there a setting or something Im missing? I get collision limit exceeded messages sporadically too, but after setting it from GPU to CPU like suggested, its worse...
Any ideas?
Thanks in advance
Simon

EDIT: Seems the simulations aren't the only thing going sideways. Vibration tag is killing it now as well. New updates yesterday..... hmmmm....

Hi Simon,

I assume that would be a question for the tech support. based on your "edit" I would think you gave a lot of pointers to check with tech support.

The exact URL also has an entry for "Requirements".

The Graphics Cards perform increasingly complex calculations, and this might work fine in your setup.
But certain things need to be pulled back into the CPU, and there is often the bottleneck. moving data around.
I do not have a complete list when and how those slow-down combinations happen. I can't answer that.

I also have no idea what some presenters use to run it, so I hope tech support can tell you more about your specific setup. I do not do anything hardware-related here.

My tip, try to cache the scene and see if that improves everything.

All the best

Cheers, Ill get on it if this is persisting...

Fingers crossed it doesn't persist, Simon.

Otherwise, I hope the tech support can help you.

One more idea: you can also check Cinebench to see how your setup performed.
