Lag at the render viewport

Good evening,
I have noticed that there are too many delays when processing a model in render viewport

Hi Πέτρος -

Please run the Rhino SystemInfo command and copy-paste the result here.

Thanks, that looks fine.
When you create a simple box in a new file from a factory-default template, do you notice “too many delays” in the render viewport?
Also, what does “render viewport” mean to you? Is that the factory-default “Rendered” display mode?

I have made a model which is not simple. It has many details and many surfaces. I have added materials from V-ray and when I choose PERSPECTIVE VIEW with rendered display the mouse movements lags too much … i can’t zoom, i can’t rotate the object. Ηowever when I return to shaded display movements are carried out without any delay.

Hi -
What happens when you disable the V-Ray plug-in in the plug-in manager and restart Rhino? Does the behavior change?

I disabled every material I had placed on the item. His behavior is a little better. I’m handling the object a bit better, but there’s still a lot of movement lag

Hi Πέτρος -

My question was what happens when you disable the V-Ray plug-in.

explain me how to do this action

In Rhino, run the PlugInManager command.
Look for V-Ray in the list - you can change the pull-down menu to only display plug-ins that do not ship with Rhino to make it easier to find:
Uncheck the plug-in in the “Enabled” column and restart Rhino.

disable what I have highlighted. Right ?

I’ve never used V-Ray but it looks like there are two plug-ins that include that name. You’d want to disable both to make sure…

if I deactivate them, will I be able to activate them again if they are useful to me?

I turned them off and it lags too much again

apart from the very long delays caused by the model when zooming and also during its rotation there is still a problem with the projection of the lines as I show in the image below. I don’t know what’s going on and I need help with both my 2 issues
