Apologies in advance, this is a really vague issue.
I've been working on adjusting my workflow to better suit/take advantage of V-Ray 3.1 for Maya (2016). I was using 2.1 on Maya 2015 for about a year.
Most of the projects I work on are pretty similar. Animations of internal computer components rendered at the macro level. Sometimes the animations are all CG, sometimes they are composited over footage. I mimic a light rig that we use for shooting that consists of a white acrylic reflective table, and 5 or 6 Kino-Flo 2ft. 4Banks. I either use an environment map that i've captured, or I copy the setup/dimensions/lumens using V-RayRectLights. I use a camera with a the physical camera properties attached (on the video setting), and I usually match the focal lengths/iso/f-stop/sensor sizes we use in the studio.
This has all been fine and dandy. I usually render at 1920x1080, or sometimes UHD. Even with most if not all of my materials having blurred glossy reflections, and normal maps, and with the camera having both DOF and Mblur, I get renders in the 10-20 minute/frame range with acceptable noise levels. With V-Ray 2.4 I usually had 12 to 16 max samples, sometimes the light samples would be ramped way up, and the DOF samples would be doubled (I understand this option was removed as it just increased the AA samples anyway).
so, enter Vray 3.1. I'm getting really noisy renders, and they're taking upwards of 30 minutes a frame. Glossy reflections seem to be taking longer, but when a glossy material is in the blurred DOF section of the frame, it seems to go up exponentially. I keep trying to isolate where my issues are (I refer to this tutorial a lot http://www.cggallery.com/tutorials/vray_optimization/), but there just doesn't seem to be any getting around it.
Did v-ray fundamentally change DOF, and reflections? is it expected that they'd take longer now? I justified the cost of upgrading to 3.1 to my boss by saying it was supposed to speed things up, and now I'm missing deadlines because of the upgrade.
I'm really interested in any insight at all that might help me improve my render times.
I'm running Maya on OS X 10.10.5 on a 2013 15-inch MacBook Pro with Retina Display, and I usually render on a small farm of 7 2009 12-Core Xeon Mac Pros that are all on OS X 10.9.x. When I'm doing lookdev, I use DR and/or RT, and then I use Backburner for batch renders. I usually use the adaptive sampler, but it doesn't seem to matter which one I use.
