UPD: Solved ! Forgot to switch to 144hz in Video Card panel settings !
Bought yeatsraday ASUS ROG SWIFT PG279Q - And everything runs smooth and pretty nice, but after i quit from games, or apps wich are running full screen - my monitor drops hz from 144 back to 60 ! What can i do to fix it ?
*Installed latest frimware update from official ASUS support web-site, but couldn't install drivers (didn't find .exe file) !
