We have Vray 2.0 and Max 2013 running on 6 machines and they all have the same issue since day one of installing 2.0. In very basic scenes everything acts fine. But in more complex scenes with more geometry, materials, proxies, etc., there is a few second delay when clicking into the Vray Frame Buffer. After the delay, the frame buffer acts just fine and responsive. But once you click back into your viewport or anything in Max, there will be a delay again the next time you click into the frame buffer.
Sometimes during the few second delay, the frame buffer disappears entirely before reappearing and becoming responsive. In the worst circumstances, the frame buffer flashes, appearing and disappearing many times, and you have to wait as long as a minute before it stops flashing and allows us to use it again.
We haven't been able to determine what makes it behave better or worse other than that it happens most often in complex projects. It's extremely frustrating and really slows us down once it starts behaving this way on a project. If anyone has had a similar problem or could help us shed some light on the issue, that would be very much appreciated.
