Question / Help OBS NDI doesn't look so smooth

#1
I've been messing around with a dual pc stream setup recently because I would like the maximum performance out of my gaming pc. I first tried using the Avermedia LGHD 2 but I couldn't seem to get both my desktop and microphone audio to transfer over to my streaming pc simultaneously so I decided to try out the OBS NDI plugin. Everything seems to be working fine but the only issue is that it doesnt really look as smooth as when I single pc stream. I would like to stick with NDI streaming due to the fact it can do fullscreen only game capture unlike a capture card.

Here are a couple things about my setup:
For both PC's
-OBS Version: 23.0.0
-NDI Plugin: 4.5.3

Gaming PC
-8700k
-RTX 2080
-Base/Output Res = 1080p/1080p30fps
-x264 with a bitrate of 3500
Streaming PC
-4690k
-Gtx 660
-Base/Output Res 1080p/720p30fps *I have two monitors, both hooked up to gaming pc via DP (144hz one) and HDMI, streaming pc hooked up to 144hz via HDMI output on there
-x264 with a bitrate of 3500

My internet speeds are 300mbps download and 11mbps upload as this is the best speed I can get in my area. I'm sure both are hooked up via a Cat6 or Cat6e ethernet connector on the router. I don't use the gigabit switch thingy so could that possibly be the reason why? Or is it my internet speeds, but the image quality looks fine?

For Reference:
-Here is a vod of the ndi stream: https://www.twitch.tv/videos/387266809
-Here is a vod of the x264 single pc stream: https://www.twitch.tv/videos/387267843

Anyways, hope this is enough information for anyone to help me. Sorry for the very long post. If u guys need a log file, please let me know. Would I get it off the streaming or gaming pc?
