thank you all for advises, i made my conclusions
Thanks for the answer, but I can say that I tried it all.
I having some problems working with NR
1. is it normal that NR completely take away all the resources of a laptop? When I apply it, I can’t work normally even with proxy files. Last time the effect was applied for almost 50 hours to a 20 minute video.
Now I suffer with one minute project!
2. even with such a heavy render, my processor is no more than 30 percent loaded, while it I can’t do anything else on the laptop, and all the RAM is occupied by FC
maybe there is some kind of algorithm for working with NR ?
