AA Samples VS Denoiser
Posted: Wed Aug 08, 2018 6:16 am
I'm interested in the tiled sampler cause it seem to allow use both cpu and gpu even when scene wouldn't fit into gpu memory.
I wanted to try and find out how AA samples affects performance and I found it not working very well with denoiser. What happened was using 16 AA samples somehow breaks denoiser. At first I thought maybe since it needs more passes to make denoiser work properly so I left it run longer but didn't help at all, then I thought maybe it's broken only with OpenCL, so I switched to CPU but didn't help either. BTW I didn't take screenshot but the AA at 16 was waaay cleaner than AA 1 at similar time, yet denoiser completely failed I don't know why.
Another thing that I find weird is that I use i7 4770K and a 6GB gtx 1060. In cycles it would seem using cpu+gpu would roughly double the performance compared to rendering 4770K. However using 16 AA samples with luxcore seems to be pretty damn fast using cpu+gpu but cpu is waaay slower on its own. Way slower than half the performance, maybe more like 1/8th (didn't do the exact math) is this behavior normal?
