Computer Lag

[vjaramillo]

Has anyone experienced any latency on the computers since the install of VrayNext. Not sure what's causing it, but we recently updated to the latest version of 3ds max 2019 and VrayNext Update 1 on my performance has decreased. Big time desktop lag and in app lag.

Nothing for me since the update, however, I had to kill Microsoft's Shadow Copy, which caused a horrible lag.

Huge lag here for a lot of us the studio (Max2019 on Windows 10). Material editor lag could be related to new shaderball rendering, but even simple things like opening Max Render Settings takes over 10x longer than it used to., something like 5 - 10 seconds for any VRay dialogue window. I'm not positive it's due to VRay, just probing...

The rendering of the whole set of shaderballs (24 of them) on a puny 1900X takes around 2 seconds in all, the first time a material editor has been opened in the max session.
What you guys are seeing are the initial stages of max's Qt transition for its UIs, and the old UI controls now get translated behind the scenes by Max, which is responsible for the slowness.
There are ways to improve the lag a bit (albeit not to the levels of pre-Qt), and Max itself gets marginally better with more recent Max versions, but to be sure to get around (most) of it, you'd need max 2022 and v-ray 5.2.
Notice this isn't purposeful gating: it's the unfortunate case of tech maturing slower than we'd all perhaps have wanted it to.

Using V-Ray 5.2 on earlier Max than 2022 is very possible, and will at least cure the slowness in the Material Editor UIs.
