If you’ve got a phone, you can activate the 160Hz option by using the Android Debut Bridge (ADB) PC app. Then, you run the following command from a prompt or terminal window: “adb shell setprop debug.vendor.asus.fps.eng 1” (XDA has more on how to do that in its post). After you reboot your phone, you’ll see the 160Hz option in Settings >Display>Refresh rate.
XDA tested the new mode with Pac-Man, confirmed that it ran at 160 fps and believes that other games will too. However, performance could be wonky and you’d be changing the setting at your own risk. In any case, it’ll be hard to get an ASUS Rog Phone 3 anytime soon, as it’s not coming to the US until Q3 at the earliest and it won’t ship in Europe (starting at €999) for a few more days.
