Good news is you have very minor encoding and rendering lag.
If you don't already:
Limiting your frame rate in-game will help a lot in getting the best quality out of your hardware in regards to recording/streaming. I recommend using MSI AfterBurner or EVGA Precision to cap your fps to your monitor refresh rate, or 1-3 frames higher than your monitor refresh rate will generally resolve the issue of screen tearing. Try to avoid V-Sync as it can induce input lag.
If you do already:
Just need to dial back the in-game graphics options every so slightly and it should clear it up.
To note, the bitrate of 2500 is very low, you could raise this for better quality streams.
Just take note in your log file for dropped frames due to bandwidth after streaming.
Also be mindful of your audience, the bitrate you stream at is what they have to have as a download speed. Too high and some may have issues with buffering/hitching whilst viewing your stream content.
