Scene opened in V-Ray 3.3 renders extremely slowly

Hello and thank you for a terrific plug-in! Until recently we have been using Max2015 and SolidRocks 1.65 which have been working smoothly. The other day I upgraded to MAX2016 and SolidRocks 1.95, opened the scenes that rendered fast and smooth on the previous versions and discovered that these scenes now are rendering extremely slow. I am using the same presets (as in 1.65) and the new V-ray 3.3 features without changing materials, lighting or other scene elements. This is specifically a problem with (complex) interior scenes, transparent materials that previously rendered fast can now be very slow. Before I start to dive in to the different settings, is there anything specific I should look for?

Thank you, I'll give it a try

After turning off all the new V-Ray 3.3 features, render time went down by 50% and the quality increased tremendously. I think I need to dive deeper into this...

Regards

How Do you turn the 3.3 update features off ?

Hi, just turn everything off under the "VRay 3.3 + goodies" tab
