Are you using Vray 2.3 with 3ds Max 2010 or higher?
Yes, then you should have a look at yesterday’s post on CGChannel by industry vet, Jim Thacker (of 3dworld ex-editor fame.) In the post Jim highlights Intel Labs Embree technology, and how Chaosgroup has used this tech to create VRayEmbree.
Embree is a collection of photo-realistic (Monte Carlo) ray tracing kernels with support for SSE and AVX instructions, first released as beta this time last year.
This impressively produces a reported 30% increase in performance on Intel’s latest 64 Processors. The good news is it’s free.
This page also features a 2.5minute video overview from Intel, with the compulsory ‘German scientist’ in an official-looking white coat, and we all know you can never disagree with any facts from a guy in a white coat.
