[Max] Bug Reporting / Very slow geometry phase 10x slower than old pc

« on: 2024-03-11, 13:23:52 »

Hi, i have a new pc and the geometry phase is very very slow, mostly 10x slower than my old pc & and the scene parsing is mostly twice slower???

The new pc is an AMD EPYC 9754 (9004 Genoa) (singel cpu) on a Supermicro board with 384 GB DDR5 and the old pc is an AMD Ryzen 5900X with 128 GB DDR4.

I testted it with 20+ scenes all the same result, and is see the following times:
new pc(max 2021 and corona 11):
scene parsing 52 sec, scene geometry 97 sec, render time 12 minutes @ 850,000 samples/s actual average

old pc (max 2021 and corona 11)
scene parsing 30 sec, scene geometry 13 sec, render time 95 minutes @ 115,000 samples/s actual average

I also tested with the corona benchmark at 31 832 636 (9th place in the ranking) and with Vray benchmark 132950 (5 th place) so both very very fast, I am lost what to do?

[Max] Resolved Bugs / Corona 4 CRASHES ( Computing Sec GI or PROXIES Issues )

« on: 2019-06-25, 20:59:08 »

Hi. Since i installed corona-4-3dsmax ( the latest vesion ) all my projects started to collapsed !! IT crashes when its doing " Computing SEC GI . And i im prety sure its related to prxoies, becouse , after i isolate the proxy in question, the problem is gone.  Or if a delete the proxy the problem is gone. What is going on , we are 3 people in diferent locations having the same problem. And we start all our files from zero and at some point , we cant know how or why, max crashes. The only thin we know for sure that it start to happend after we have proxies in the scene.
It never happend before with older versions of corona.

3ds MAX 2017 sp3, windows 10 64 bits, double xeon, 64 gb of ram, etc. The system never failure, but as i say, it happend in diferent files in diferent computers !
