In max 9 with vray 1.5 RC3, there is a considerable slowdown (sometimes after 5min or longer it won’t start) starting the render when there are lots of objects, when in max 8 vray 1.5 RC3 it almost instantaneous. Also stopping also takes longer. Scanline and MR do not have this problem.
P.S. Vlado, i have sent you an email with a problem file max 8. Note starting the scene from scratch in max 9 doesn’t change a thing.

Yeah, it has been reported already. I’m not sure what has changed in max9 to cause this, but I’ll be looking at it. I think this was not the case with the max 9 beta versions.

Thanks for the quick reply.
Daniel, please check your email.

whats the solution to this? We’re getting the issue here with our new max9 that just got shipped.
The solution is an updated build. You can email me if you wish, but I’ll try to get a new download on the site soon.
Best regards,

We can wait I think. Were still just evaluating the max9 at moment, nothing crucial.
I have the same problem with 1.5RC3 right now and it really bothers me 
I have to wait about 3 minutes for every testrender to begin.
I had this problem with vray 1.47.xx a while ago when rendering a character. It only occured when rendering a specific object if I remember correctly. Very anoying.
