Hi, the 3rd frame start to crash, did you load my 4k precalc or make one by yourself?, on the freeze matter was on every single frame, when it passes 25 or 30 passes it hangs (single machine) for a while, then it continues normal, on DR the matter is that it takes longer with DR than single machine, like 20% longer.
i can confirm that all machines have same 3dsmax version, corona version and windows version.
