View Full Version : General Rendering Question....

12-03-2018, 02:36 PM
So I was testing a scene and I noticed that the preprocess pass took the same time on my 32 thread Ryzen desktop as it did on my 8 thread i7 laptop.
Is this normal? I checked task manager and it shows cpu usage at 100%....the only other difference between the 2 machines is the laptop has 48gb ram and the desktop has 16 (yes, yes, I know...Im just waiting for fedex to deliver the ram for the desktop).

Any insight would be great, it just seemed odd that the times would be the same.

pre-process? You talking about interpolated gi (blue bar), or the scene prep (green bar)... cos scene prep is usually subdividing/triangulating geo, etc, which (I believe) is single threaded.

Gi, SSS, FFX..not subdivision and geometry prep. On laptop it took about 7 minutes...desktop about 7 minutes...I watched the desktop and cpu usage is 100% and using all the threads...so at minimum I would have expected the preprocess to come in around 2 minutes on desktop.
