I upgraded to tS7.6 and new Vray1.53. It has been doing fine the few times I used it then suddenly it has started running very slow when I go to render with Vray. Before when I looked at task manager it was using all 4 of my quadcore CPUs at 100%. Now it uses just 20% of the four cores when it goes to render (I do have multithread checked). I uninstalled Vray and reinstalled it and get the samething, any ideas?

Vray doesn't seem to release memory like it should.

I right click the vray settings and click reset for the first step. Then I switch to another render engine and render the scene once.

It usually brings things back to normal. Also, make sure your HDRI isn't active with settings, that will bog things down.

Well I have played with this more and when I am in Model mode then Vray is very slow. Then in Workspace it renders at it's normal speed.
