Computer hangs/freezes while rendering

There's another "similar" thread on the forum : https://forums.chaosgroup.com/forum/...-3-6-vfb-hangs
Windows 10 is clearly having massive performance issues.
I too had to revert to Win 7. As I read somewhere, if the system is installed in UEFI mode, Windows 10 basically overrides all the BIOS cpu C-states and general TURBO throttling which in a heavy multi-threaded application can cause issues I suppose.

What I can see is that the common denominator for all the latest Vray issues is 3ds Max 2018, and not the OS, vray build, graphic drivers or system specs.

I'm currently working on a 15K ? workstation that on Windows 10 and Max 2018 performed far worse than my old core i7 3930K running Max 2014 and Windows 7.

In my case 3ds Max 2018 performed 50% worse on Windows 10 than on Windows 7, and 100% worse than Max 2014-2016.

You mean PERFORMED as in rendertimes?

Not rendertimes. Those are basically the same. I was refering to general program/UI/viewport performance.

is there a way to tell vray to use less threads?

I recently started with a new company and we purchased 3dmax and Vray. I had these same issues with freezing/hanging of the viewport. Rendering with progressive AA was the only way to work. However I just tested rolling back to 3dsmax 2017 and this seems to fix the issue. I still get some small hangups but these can be fixed by setting max to low priority in the task manager.

Hello,

is there a way to tell vray to use less threads?

There was a similar discussion here:

I've written a small note about changing affinity a few post below it.

Best regards,

when this will be properly fixed please?

Hello everyone, same problem over here using Vray for Sketchup 3.60.01 on Windows 10. I am using a dual Xeon 44 core machine with two 1080ti cards all drivers up to date.

Setting thread priority to low on every file I work on every time I open it seems to help a little but not enough to serve my clients.

Vray is not useable at this time I have deferred to Thea and Modo on the last couple of jobs.

Issues started with the creators update. Is there a fix for this in the works?

An interesting detail is that with thread priority set to low the viewport render works and responds very well until I open the asset editor and then the lag starts.

Setring up the environment variable helps only a little i wikl have to elaborate whether i will have to rake off one core or more. Something has to really be done about this its so annoying. Without the variablw the computer is unusable while rendering.
