Question / Help CPU usage 100% ingame and insane lag on stream with 2 PC setup

#1
So I recently decided to go for a 2 PC setup.
Specs of the streaming PC:
Intel i5 9600K
Motherboard Prime Z370 from ASUS
RAM: G.Skill Aegis DDR4 8GB
I use the integrated intel graphics for GPU
I use the elgato pro 60HD as capture card

After testing and troubleshooting a lot I cannot find the problem why my stream is lagging like crazy and my CPU is using 100% of its power. I even tried to go back to 720p60 and it still uses 100% of the CPU power with stream lagging. Whenever I start the stream OBS tells me encoding overloaded.

Log of me trying to stream 1080, 900 and 720p60:

So, I just checked and when IDLE with preview on my OBS is using up to 30% of the CPU. I'm thinking it is because I don't have a GPU in there and I'm relying on the integrated graphics?

you run single channel instead of dual channel, so half the ram bandwidth + your IGPU doesn't have dedicated ram, so uses your system memory too, so additional load on your ram. I would say most of the time your CPU is waiting on data (which is still cpu usage), and that is the reason for the bad performance.

I have a same problem
High CPU usage at both x264 and QickSync, what do I do wrong? PC-only stream, the signal goes from the Elgato Thank you
