Why are you using the "fast" x264 preset? That should be on veryfast instead, see if that helps.

[dodgepong]

Veryfast is preferred.

I also recommend using Display capture rather than Window capture on a Mac, and then crop it. Window capture is pretty slow and inefficient on Mac, especially when capturing a large window.

base resolution: 5120x2880

This is probably your culprit. Don't use a super high retina resolution as your base. If you want to stream at 720 try setting base to that (like your output). Less work for your system.

Also if you are capturing apps that use OpenGL I would recommend doing it with Syphon instead of window capture, you'll get much better performance.

So the issue with the lag was the window capture is really bad on mac like dodgepong said.i switched to display capture and theres no lag. also my base resolution is 5120x2880 because my iMac is 5k. thank you for the help fellas
