right now im running a intel i3 4160 with an evga gtx 960 ssc. i looked at some settings and some youtube videos and turns out you can actually use both cpu and gpu to render if you have it set to auto or something like that. but i remember reading on a site a long time ago that using the gpu to render can make videos choppy. is this true?
