So, I've just built a new PC for rendering: Overclocked i7 5960x running at 4.6GHz, dual Titan X GPUs. 64Gb RAM. Its very fast for my usual 3d rendering but I noticed that it seemed slower than my rusty old 2012 iMac. So I did some tests. Both running cc2015, both with settings the same and scene the same.
On the PC, 10 second sequence took 2mins 24 sec. On the iMac same scene took 8 seconds!!
The ram preview on the PC only took 8 seconds, (at full quality), but rendering (image sequence) is taking 2 mins, why?
Any ideas what could be causing such a huge slow down on the PC?
OK, I think I've solved it. I was saving out as a Prores movie on the mac, not an image sequence. Once I changed to a movie format on the PC it was just as fast. Phew!
Sadly though, we don't have a format half as good as prores on the PC.....
