Question / Help Stream Choppy with Elgato HD 60 Pro - Crossposted from Elgato reddit.

Hello, I have been streaming Quake Champions (which is f2p on steam right now until the 18th!) from my single PC and wanted to give a shot with the 2 PC setup recently. The single PC setup works great but it also causes some decent fps drops and input lag which can't happen in high level Quake gameplay :( . I am having some serious choppyness when I use the 2 PC setup and can't figure out exact issue. I will list specs of both PCs and explain how I have it running currently.

Gaming PC:
Ryzen 7 1700x @ 3.9ghz
32GB 2933 RAM
GTX 1080ti
Evo 950 NVME ssd
ASUS ROG SWIFT PG279Q 27" 2560x1440 165hz gsync monitor
Asus 1440p 60hz monitor (secondary)

Stream PC:
i7 4770k@4.5ghz
16gb 1600mhz RAM
Intel HD4600 Integrated GPU
Elgato HD60 PRO capture card
BenQ 24" 60hz monitor

I have HDMI running from my 1080ti in the gaming PC to the capture card which is in a PCI slot on the streaming PC. I have Nvidia control panel on the gaming PC setting the Elgato as it's own display and is running at 60hz. Gaming PC main monitor running at 165hz and secondary monitor at 60hz.
Using OBS on both gaming and streaming PC to transfer signal. The gaming PC has OBS open with a scene that has game capture source. I then right click the preview and do fullscreen projector to the 3rd display(which is elgato). This then shows the game in the OBS on streaming pc.
Streaming PC output settings are as follows:
X264
CBR
Bitrate
6000
Keyframe interval 2
Veryfast preset (tried ultrafast and superfast but same choppyness)
Profile Main
Tune None

Here is a 10 min clip of the 2 PC stream setup where you can see choppy ness.

Here is a clip of the single pc setup - the smoothness is night and day but single pc causes some input lag and fps issues I'm trying to avoid with such a fast paced shooter. https://www.twitch.tv/videos/273823084

I have tried fresh installs on both PCs of OBS software. Uninstalled Elgato and reinstalled drivers + HD software. Fresh scenes on both OBS with nothing but game capture active from the gaming pc. Fresh Nvidia drivers.
Any help would be greatly appreciated so I can make use of this Capture card...too expensive to be a paperweight :( I hope I included the important information. Let me know if you need any additional information to help troubleshoot.

I don't see anything necessarily wrong in the log, you dropped a couple of frames, literally. The problem is in the capture device, do you have the latest FIRMWARE or Drivers for it... Latest Windows update may have overwritten drivers or corrupted them. Try a fresh installation of the latest drivers for the Elgato and ensure the Firmware is up to date as well...

Thanks for the quick reply. I just recently updated to Windows 10 1803. I just uninstalled elgato hd60 pro via device manager and then reinstalled with latest drivers from elgato site included in Game Capture HD. I'm pretty sure I also ahve the latest firmware but unable to check because I believe they removed the option from Advanced tab when you hit ctrl+click settings. I have increased the quality to the highest bitrate on the elgato and it seems to maybe have removed some of the choppyness but still not nearly as smooth as it should be. I will link another test vod.

Hmmm can you detail your settings or take screenshots of the settings for the Elegato as many or all of them as you can. Thanks!
