Mouse cursor Lag in Unity Editor user interface

Question

I have 144 Hz monitor, when I move mouse around Unity Editor interface the it feels like the Unity drops refresh rate to 30 Hz (The mouse movment is very laggy, compared to other software's interfaces). Any suggestions how to solve it? THX!

Answer 1

While the accepted answer certainly does work, if you rather use a targeted approach you can also change the monitor refresh technology for Unity.exe to fixed in the control panel. This will address it for Unity and not force GSYNC in full screen only for other apps. You have to restart Unity for it to take affect.

Answer 2

after digging around I found that GSYNC was the issue. After switching to ONLY FULL SCREEN mode it worked!
