Terrible, choppy playback no matter what I do

[LizzyPotatoes]

I mean, it's terrible. I've attached my system info and here's the link for the log file https://obsproject.com/logs/haNcRwy3qHvLChtb.

I'm simply trying to record Minecraft for Youtube videos and the video quality is really choppy and totally unusable. Can anyone please help?

Thanks very much y'all. This is really deflating.
