This is something I never had before.When rendering with the ADV renderer, my mouse lags while trying to do some basic windows functions, or even color correcting with the VFB or whatnot. Sometimes the whole computer just hangs for a few seconds, nothing moves or anything and then it unfreezes and I can see the buckets have moved a few times in the meantime. In every scene, simple (material testing scene) or complex (interior with lots of bounces etc), it doesn’t matter. This is AFTER I did a complete format and reinstall of my system and upgraded from vray 3.60.01 to .03. I don’t want to roll back just yet.

i have the same thing o dual XEON machine - setting low render priority doesnt help at all
i started encountering this with the newest incarnation of WIN 10
its MEGA annoying
problem is that when i set the processors affinity to a certain application, it never remembers and i have to set it up every time :-/// it resets itself even when computing LC…and imagine when i do animation
CPU problem , At work i have i7 with 32 Gb ram, and with “Low treared priority” checked in vray Settings tab i still can use Photoshop and edit some raw’s and render at same time. At home i have 2 diferents workstations both dual xeon, and if i try to work on Ps while render it freezes alot. So i think behaviour it’s comon with dual CPU.
Anthonyh and Glorybound, sorry but i think you in the task manager go to Details tab, not in Process and you can find 3dsmax.exe and change to “low priority”
We have this problem lately in 3ds Max 2018. Whilst rendering the whole computer freezes up including the VFB and you cant cancel a render and have to wait until it is done. We have to force crash 3ds Max to stop a render which is not ideal at all. It happens 95% of the time with progressive and bucket. Never had this issue in 2017 so thinking Autodonk may have broken something
I have the exact same problem but only when using bucket rendering and only for a few seconds at a time, but is hangs often enough to make doing anything else on the workstation impossible. Low-thread priority enabled. My system is an old Z820 with dual Xeons and 64GB of RAM.
Same problem indeed, with progressive I don’t have this either. Forgot to test. Guess I’m using progressive for now. System is probably just as ‘old’ and more or less same specs but that isn’t the problem.
Didn’t have this before (3 year old workstation), I did a format with the exact same OS I had before the format. Though it might be .03 version but I’m not willing to do a rollback.
Edit: some scenes also have problems with progressive with more or less the same result.
I have had the same problem of late, Vray 3.60.02 in max 2016 on windows 10.
I thought it might have to do with the fact I use Bitsum Process Lasso but have not taken time to test and investigate. If I remember to set vray to low priority it seams to work fine.
Same problem on two identical machines, also HP Z820. But we are on Windows 7.
It helps to assign 3dsMax to one core only, then the lag is gone. Afterwards you can set it to all cores again using the taskmanager.
In the settings or in task manager? I wonder, because “Vray” isn’t really a task in the task manager it’s only 3dsmax, that’s hogging 99% of the CPU. When I put 3dsmax to low priority it does work to a certain degree but not like I had before. Besides this is bullshit I’m not going to click another extra 5 times with every test render. That is just insane. And isn’t the render going slower then with low priority?
Can this be solved within Vray or do we need to tackle Windows? @vlado what do you think?
You should only need to set 3dsmax to Low priority process, Vray should inherit the priority (at least in Win7) and you only need to do that once per 3dsmax session. Alternatively you can create a batch file to run 3dsmax low priority I think. We do this for backburner so I`d think 3dsmax probably has the same or maybe a command line code you could add to the 3dsmax icon shortcut ?
That’s not true!
Select the 3ds Max app in the “Processes” tab of the task manager and right click, select “go to details”. On the Details tab, with 3dsmax.exe selected, right click and select “set priority”, then select the priority from the menu.
Not sure this helps in the grand scheme of things, but thought I should point this out.

edit: just noticed that someone else pointed this out too… Sorry.
No I just do it i the vray settings panel, the “Low thread priority” setting, that works fine for me.
If I get a chance I will test what, if any, performance difference there is. It still uses 99% of the CPU process when I do this, although I assume it does drop more when I tab to other programs.
Problem is that in the low thread priority in the settings doesn’t work or doesn’t have any effect. When I do it manually (task manager) 3dsmax > low priority it does make a difference.
