Render Setup Window slow dragging after windows update 20H2

[nmoser]

Morning,

After updating windows to version"20H2", I've noticed that Vray (Next) Render Setup window dragging is very slow.
I believe that this problem is related with vray because by changing to another renderer this problem goes away. If changing to vray GPU the problem gets worse.

This is Max 2021 and Vray 3.2

I've tried to update the graphics card drivers but the problem remains.

Thanks

Thanks for the report. It does seem to happen on some of our machines. I've logged the issue (internal bug-tracker id: VMAX-10912) for developer investigation.

Hi this problem seems to be something more general, as the main window for example and others unrelated to V-Ray are affected too. We've reported this to Autodesk for advise. As well there were changes in the UI that were planned prior to this that could improve performance, still it's not very sure as Arnolds settings for example seem to exhibit lag too, just significantly lower.

Best regards,
Alexander
