Hey guys, I made two short videos showing you the difference between CPU encoding and GPU encoding.

Please take note that I have some pretty good high-end hardware and for the most part I have a dedicated 4k capture card. However, for those that want to see which one will suit you here are the videos.

tl;dr:

If you are lacking in CPU power and you can enable NVENC, then stream/record with it.

Not sure what type of OBS feedback or suggestion you're offering here, so moved to the Questions and Help forum instead.

i have an i5-4670k with a GTX 760 and am curious if enabling NVENC would help in anyway. I had no hiccups yesterday playing Outlast in very high maxed out settings and streaming at 3,500Kbps. It's my understanding NVENC would take the load of encoding off the i5 and put it on the GTX 760? Why would anyone ever want this? Wouldn't you always want every bit of power from your GPU used for the game?

On a side note, i tried using intel quick sync when I was gaming with only the built in HD 4600 and it actually resulted in 10 FPS less for the game I was playing which was Loadout. I was getting 30FPS just using the IGPU but then I turned on QuickSync and I was only getting 20FPS.

well the keplar chip encodes it on the 760 or actually every card from nvidia with the keplar architecture while the cuda cores still do their thing and process the game you probably lose at max 1-3 fps

but if you run an haswell chip i would recommend going with qsv if you got an i5 maybe even with an i7 since haswell quicksync is pretty beast and does very very well compared to x264
