Question / Help CPU Jumping around in huge ranges (50-100%)

So I'm curious as to why when I record with my capture card (Elgato) my CPU ranges spike so badly? I have nothing open buy OBS, no internet, skype, or anything else, just purely OBS. I feel like my computer should be able to handle just OBS + Capture Card recording. Isn't Capture Card recording suppose to help the CPU because the PS4 is doing all the harder work in playing the game? When I play something like Fallout 3 or Pokemon and record, I don't think the CPU ever spikes that badly or even ever / rarely reaches 100%?

Try OBS MP https://obsproject.com/download#mp build that uses VCE (hardware encoder) or the original OBS with VCE support added https://obsproject.com/forum/threads/obs-branch-with-amd-vce-support.13996/

your cpu isn't very strong so software encoding with 1080@30 is a bit much for you. your hardware encoder in your AMD gpu should be fine with 1080@30 for local recording

But, the weird thing is, like I said, that when playing Pokemon, on my PC, while recording, I don't generally have these issues at all or very little. I thought capture cards took stress off the PC? Or is it just because I was recording Star Wars Battlefront Beta, which is more intensive in-game than Pokemon? I"m just curious why the capture card recording is using more PC usage than Fallout 3 on PC or Pokemon on PC + recording.

Yes, capture cards take stress off your gaming PC and put that stress on the streaming PC. with only 1 pc. there is nothing to move the stress to. with one PC, it just puts the load back on itself.

Huh, so basically it will just put stress somewhere else? That's odd. :/
I'll try out the two links that you gave me. Will downloading either of those change anything in my current OBS, or is it like a separate OBS application that will come up fresh? Which of the two would you recommend trying first / working better?

Well encoding the load has to be done somewhere right?

OBS MP is a complete new build of OBS. it is different and still is very active development but has enough stability to use on a regular bases (IMO).

the VCE fork of OBS just adds the VCE support to that build of OBS. read the front page if you want to use that build. I just put that build directly on my desktop and run it from there. This build will use OBS current settings so I recommend to save a preset in settings. the only real difference will be adding VCE support in the encoding tab, and of course adding in the AMD VCE settings tab.
