My collegue works on 2990wx and I am on i9 7900x. His renders are about 2x faster but I noticed but his viewport often works like sh*t. Opening Maya hypershade…oh man… I tried to convince my boss to wait few months with for 3970x..we eventally got 3970x for another machine and it works MUCH BETTER also rendering wise.
With a 2990 I had a ‘good fun’ for a couple of month, once started working from home and started to use it every day 8-16 hours.
I did several of fresh windows updates, bought and returned couple of sets of memory specifically designed for 2990wx and which been listed in QVL of mobo, and CPU.
Tried different bios, different amount of memory. (64gb works a little better then full 128gb)
I’ve spoken to multiple of guys in discord, facebook, and others. Sometimes felt that I’m the only one who’s having problems with it. At some point I really could prep the scene for render on an old i7 5930k, then on this 32 core motherf*cker.
Obviously I do have coreprio setup, got AMD ryzen master etc.
And after all this I gave up, I’ve cut 4 cores from rendering for VRay using Environment Variables, and it’s sort of helped a tiny bit. But Corona still turnes it into pumpkin magically.
But to be fair it’s rendering real good, we’ve got 10 machines at work as a rendernode, and they just perfect for rendering purpose only… once you solve memory issue lol.
I really have very few issues with the 2990w here. Phoenix is a little faster on other machines, but VaRy runs great. Max is no slower than any other machine. I like to simulate Phoenix on another machine anyway (Ryzen 9 iirc).
Oh, the other thing that runs slow is Max hair and fur, but if you reduce the setting in the environment plugin (voxel size or count or something) down to 3 it is again as fast or faster than anything else other than the new threadripper.
We do use coreprio. And comparing 2021 only. That alone was a big UI speedup, but Max is still crazy sluggish on any hardware.
thanks for the suggestion, once i get deadline back up and the new machines ill look into that. sick of spending money on cloud farms
I’ve downloaded this: https://bitsum.com/portfolio/coreprio/
Apparently, there can be performance improvements once you enable the options. Numa related, so hopefully, this will help. I may also need to disable NUMA in the bios. I’ll report back.
I forgot to mention that I’m using a 2990wx threadripper CPU.
Please do report!
If there truly was a certain, simple way of mitigating it, you’d get the eternal gratitude of countless users!*
*Slightly exaggerated for the sake of drama…
EDIT: reading on coreprio’s data page is sobering, and somewhat comforting to the issue at hand.
What is the issue?
Nobody knows. Or at least nobody has communicated such. Whether it is core thrashing, a memory channel bottleneck inherent to the NUMA allocation strategy, we don’t know. No theories have panned out that point to a definitive cause, leading to the speculation it may simply be some bug or quirk deep in the Windows scheduler.
What is the ‘fix’?
The ‘fix’ is bizarrely imprecise. For affected processes, a call to SetProcessAffinityMask, without even changing the affinity (e.g. all CPUs to all CPUs), resolves the performance issue – at least most of the time. Our best guess is that the preferred NUMA node for the process is removed, causing the Windows scheduler to change behavior, as evidenced by the thread ideal processor selections, and more importantly the massive change in performance.
How do I do this?
I use RyzenMaster to do so, but it can be done via boot options in windows.
Sorry to barge in here, but lately I feel my PC has gotten really sluggish. Render wise it’s ok but to work on it is really frustrating. Not sure if this started after some Windows update or if I’m just using large textures lately. I have 1950x so should I try some of the suggestions like that Coreprio? Don’t want to screw up my only work PC, and not sure if it’s only for 2xxx procesors.
Like some of the weird things I’ve noticed is that my Chrome opens like 4 times longer than normal…and other weird things. I’ve scanned the PC with Emisoft Emergency kit, and other things, they found nothing. Sometimes I feel like everything I do Windows says “please wait while we let the bosses know what you did”.
I have to reboot Windows daily, otherwise, everything crawls. I am assuming it was a Windows update because nothing else has changed.
Same here. Maybe it’s anecdotal but it also sometimes feels like it’s fine all day but then the next day is noticably slower (I don’t turn it off each day). It seems like windows is doing something overnight that it’s not fully recovering from. Another time that I’ll frequently detect a slowdown is when windows is requesting a reboot due to a windows update, could just be coincidence though.
Same here. Reboot and it is fine all day. When I get back in the AM it is crawling. It took 12 minutes for MAX to open. Rebooting brings it back to full speed.
My god software is broken these days. So this heavy scene I have, when I import an object (any complexity) i have to wait about 2 minutes whether I import an object or click cancel, I have to wait the same amount of time.
You may be wondering how bad it is…I’m listening to Enigma and still fuming!
Yep, merging is slow and a pain as well. I just found out Malwarebytes was causing my Chrome to crawl and after killing it, Chrome returned to normal. Maybe, it was slowing my machine too. I’ll report back.
I reboot maybe once a month, probably more like once every two or three months.
Has there been any update on this subject ? Could it be related to some kind of materials imported from other models (sketchup or similar) ?
Material editor is soooo slow (and i only use the 3dsmax normal preview, not the vray) and it’s not like there is 5000 materials and a lot of maps/submaps/etc etc
Same here. Slate editor is crazy slow.
Hello.
I want to share my experience on this too.
I’m working on a Threadripper 2950x with 64Gb of RAM and a RTX 2080Ti.
For me the worst part is the response with vray material properties and render setup window open/close cycle.
To be more clear I made a couple of short videos showing what’s the difference, first, with different render engine materials:
https://vimeo.com/508813456
Here we can see properties in vray materials are the slowest in redraw having to wait like 2 or 3 seconds (some times). While physical materials and arnold standard surface are the fastest and almost instantaneous.
The I did this other video where we can see the difference opening and closing the render setup dialog:
https://vimeo.com/508816098
Here scanline and arnold takes almost the same time to open (2 secs) but vray is taking like double the time (4 secs)
Is this slowiness something normal or is it happenning only to me maybe for a bad configuration of my system?
same here…(dual xeon 6136, rtx3090, 64gb ram, ssd drive)
With a 3950x/64ram/2080ti I get 1 sec delay in vray mats and only slightly quicker with others apart from physicals, which are instant.
I get just slightly over 1 sec on render dialogue.
That delay is fine for me, though of course it’d be better quicker. So not as slow as for others but that could be
similar to what was discussed here, with a possible fix - Chaos Forums
