V-Ray for Rhino is not forward-compatible, meaning projects done with V-Ray Next will not be read correctly with V-Ray 3.6 or older versions. The Hybrid-Mode doesn’t help so much, so my DualXeon could help to save 10% of the render time most, but it’s not worth for me - I get heat problems for the CPU since the GPUs are heating to much.
(min/max subdivs 1/100 works for quite universal).
If something should crash, than not the display.Īlso I found the GPU mode is faster if I disable the progressive mode. But most I use the 1080ti for system/Rhino/display and the 2x2080ti for rendering only. If I render per 2x2080ti and 1x1080ti than I get approx. Finally I bought two 2080ti and get my complex train interiors in approx. Old speed, but the detail quality is very nice, no splotches anymore and fine details are kept. So, one 2080ti in BF+LC allow to render my interiors in ~20min again. Jumping from LC+IM to LC+BF cost some render time. So, a well adjusted LC+IM setup allow me to render an interior scene in high res in 20min in the past. I was quite disappointed by the fact, that the new V-Ray based on the “new approach” without subdivs was quite slow. My impression was one 1080ti is so fast like my old DualXeon. I use V-Ray GPU rendering a lot now and I like the speed in comparison to my DualXeon (32x3,2GHz).
