Hi All, Just finished rendering out some huge (20,000 x 20,000) pixel renders for posters for a client. The images were of aircraft, so not archvis. I used to render these out in Octane because I have twin Titan-X GPUs in my machine and they are super fast right? Er..... Small frame around 2000 x 2000 in Octane, render time to noise free: 20 seconds V-Ray CPU only on my crappy old 2010 mac pro (2 x 3.46 GHz 6-Core Intel Xeon) and DR to Hackintosh with intel 5960X, render time to noise free: 50 seconds. Huge 20,000 px frame Octane time to noise free (remember these titans have 12GB Ram so no HD use necessary): 1 hour, 20 mins ** V-Ray huge frame render time to noise free: 20 mins! ! So not only is V-Ray over three times faster at big sizes than twin titans, the end result looks a million times better (of course ;-) ). I'm super impressed by that, both the mac pro and the hack are almost exactly the same speed, so not that fast by todays standards and V-Ray still out performed Octane by a big margin! NB, this is with NO optimisation in V-Ray, I don't really know what I'm doing there so I just pick default GI and default Bucket AA!! Eat my V-Ray dust Octane ** Can't wait to get my iMac Pro when they come out!
