Best Way to Stream YouTube & Twitch with OBS Studio (x264 vs NVENC)

Streaming to YouTube & Twitch with OBS Studio requires an understanding of the various encoder options from x264 to NVENC h.264 and Intelโ€™s Quick Sync H.264 codecs. In this video I will compare the different encoders while playing GTA V and share my optimal settings for performance and quality. I will also cover the basics of how to use OBS Studio for 2016/2017.

Observations:
=============================
I feel that when capturing while playing on the same PC, x264 requires too much of a CPU commitment to be recommended. I find that at about 4500 Kbps, NVENC looks just as good as x264, but offers much better performance with in some cases up to 35% less CPU utilization.

If you are capturing from an external console or PC then x264 might be optimal at low bitrates because the CPU utilization won’t be as important, and x264 does look better at bitrates below 3000 Kbps.

I think many articles available online are outdated and too harsh on the NVENC h.264 encoder. It’s what I’m going to use from now on.
