Run OBS @ 30 or 60FPS. I would get another monitor to capture from, 1080p. In the meantime, you may want to downscale to 1080p.
19:23:13.360: video settings reset:
19:23:13.360: base resolution: 1920x1200
19:23:13.360: output resolution: 1920x1200
19:23:13.360: downscale filter: Bicubic
19:23:13.360: fps: 20/1
There's more but run a test after all that is done a see if things improve.
