We added support for displacement in version 2.2, so if I understand correctly the issue you described in the first post has been happening with any versions of Vantage and V-Ray since then? And the scene is large with many objects, etc., correct? If so then it does sound like the issue described in the other thread - an issue which lies within the host application and how V-Ray interacts with it. I don’t think we can do much about it on the Vantage side.
It’s such an interesting situation. After turning on autokey in 3dsmax, it’s not possible to move the timeline slider. Would you like me to send you a video?
Are you using Chaos Scatter or Forest pack? If you are using Scatter can you please hide them and see if that improves the responsiveness. There is a bug in scatter that is forcing it to refresh every frame which is currently investigated.

As you can see, there isn’t much of a problem when my scatter objects are initially turned off. However, as soon as I enable them, the scene starts freezing. When I try to render the animation, there’s a massive delay when transitioning from the first frame to the second one.
I should also mention that I don’t experience this issue when creating animations directly in Vantage — it only happens when rendering scenes imported from 3ds Max. I suspect that the delay is largely caused by the scatter objects.
