VRay Frame Buffer Lag in Complex Scenes

[JAFoley]

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.

This bug is a pain. Ive switched my graphics driver back to DirectX after hearing its a Nitrous issue. Its fixed the buffer problems but I do miss the Nitrous viewport stuff. I thought this was fixed in Max 2013 (Im on 2012).

is there any confirmation that this bug is fixed in max 2013 or 2014 ?

after some searching found this and it works for me :

- Disabling the "Improve Quality Progressively" checkbox (Display Performance Panel for Nitrous viewports).

This worked for me too with Max 2012. Besides that, Nitrous has been great.

Damn I was going to be switching to Vray 2.0 soon and was hoping this issue was ironed out. Oh well, maybe 2014 will be better. I am running 2012 and Vray 1.5 and I too had switch to Direct X to fix the problem. Mine was really bad! Flickering FB after anytime I touched it.
