Question / Help Dual PC 1080/60 Setup?

[6ix]

On my gaming PC I send over my system to my stream PC via nginx RTMP. NVENC doesnt look as good as x264 and saves me a little in the performance department but this isn't my issue. My stream PC is a I7 4790 4Ghz 4c/8t system that chokes if I use ANYTHING except ultrafast.

My stream is HEAVY with overlays and "crap" so that may be one issue but if there is some magic that I can do to this system to make it perform better that would be great!

Encoder: x264
Rescale Output: Unchecked [Taking the 1080p resolution feed from my GamePC and uploading that resolution to Twitch].
Rate Control: CBR
Bitrate: 6000
Unchecked: Use Custom Buffer Size
Keyframe Interval: 2
CPU Usage Preset: Ultrafast <------ Looks like garbage
Profile: Main
Tune: (None)
x264 Options: [None]

Video
Downscale Filter: to both 16/32 and see no performance difference. The CPU is at 100% for both if I'm anything but Ultrafast.
Common FPS Values: 60

Advanced: Process Priority: Above Normal

As I understand the NGINX dual PC solution, you set up the overlays and "crap" on OBS on the gaming PC, and then the streaming PC only does the video encoding.

Is that how are you doing it? What guide are you following?

If that is how you're doing it, increase the bitrate out of OBS on your gaming PC. You want it to be high bitrate here with low CPU impact, so you use the minimum CPU preset but keep the quality high by throwing tons of bitrate at it. The streaming PC is where you set the bitrate back down to something reasonable for streaming.
