It’s happening to me as well , I have 128 gigs of ram , RTX4090 , and Ryzen 12 core processor , SSD nvme2 hard drives no issues on any other 3D program , I’m starting to believe the problem is occurring from content manager bottlenecking iclone haven't had this issue with version 8 now 8.5 is causing issues. “

i have the same crashing problems...upgraded to super duper graphics card and fast quality computer but suddenly motion director seems to shut the whole programe down...I have also updated the ic8 and cc4

This is an old threat, but the issue of very slow performance is still there with the latest NVIDIA drivers. I got like 8 FPS or less with a small scene with two characters.

So I followed the suggestion made by Vidius to roll back to driver version 537.38 and that made a huge difference. Something to consider if you are struggling. Whatever NVIDIA was supposed to resolve--it did not help iClone.

I am running windows 11, on an MSI gaming computer, 32gbs of ram, and iclone 8 frequently crashes. My graphics card is NVIDIA GeForce RTX 4070 Ti . That is so frustrating. Please give me some sollution. 

Yes, I did uncheck it and it does make an improvement. Unfortunately rendering with it checked back on still seems to take longer, at least for me. Interestingly, with the new driver it hasn't crashed like before, so some progress.

i had the same problem with crashes. unchecked the environmental reflection, and things worked again however, iclone 7 was being effected too. so 
i uninstalled the Nvidia driver and rolled back to the 537.58 driver (studio version) and now everything is operating as it should. it is quite clear that the latest driver is 
at fault and causing the issues.

A suggestion was made earlier in this thread to disable Environment Reflection:

Did you try that? It has worked for me.

Just to confirm, Joanne's suggestion of taking the driver back worked for me. My project is only around 3.2GB and I have a 8GB RTX360Ti and it was running so slow and occasionally crashing. (although even on small projects it was feeling sluggish). Also, rendering was taking forever. Rolled it back and Iclone 8 ran like a dream again.

I have just updated to the December 12th driver and it's back to struggling again. So it appears Nvidea have not sorted out the problem. :(

Please see the suggestions made by Joanne in the post before yours. This may help reduce or even resolve the crashing issues.

However, if you continue to have problems, please contact Support as I advised previously.
