Been using AutoHotKey, with my 380.

Save code as .ahk, edit for resolution and Hz. Start and press 6 for 1080p60, 7 for 1080p144...

​

#NoEnv ; Recommended for performance and compatibility with future AutoHotkey releases.
SendMode Input ; Recommended for new scripts due to its superior speed and reliability.
SetWorkingDir %A_ScriptDir% ; Ensures a consistent starting directory.
