Update:
The ROG Ally Graphic Drivers Version v31.0.22017.3004 released on October 27th officially added the 1600×900 resolution to the ROG Ally. The registry tweak is no longer needed as it now an option in the resolution settings by default.
How To Improve Quality At 900p Resolution
You can use either AMD RIS or AMD RSR to help improve the picture quality.
Enabling AMD RIS
AMD Image Sharpening helps improve the picture quality of your game and is built into the ROG Ally.
- Open up the Command Center, go to settings and add the AMD RIS shortcut.
- Now you can enable AMD RIS in your Armoury Crate shortcuts.
- If that doesn’t work you can Open up the AMD Software by clicking the AMD Software icon in your task bar.
- Go to the gaming tab, click the game you want to enable AMD RIS and enable it.
- In the preferences tab inside AMD Software you can enable the In-Game Overlay so you can see if AMD RSR is enabled when a game starts. (the shortcut key is alt + r)
Enabling AMD RSR
AMD RSR is a upscaling feature that’s built into the ROG Ally.
- This is important, Launch the game first and put the game to Fullscreen mode and 1600×900 resolution. Exit the game and open up the command center and turn on AMD RSR.
- Open up the AMD Software by clicking the AMD Software icon in your task bar.
- Go to the gaming tab, click the game you want to enable AMD RSR on and enable it with borderless fullscreen in the settings and select the 1600×900 resolution. You can adjust the sharpness here as well.
- In the preferences tab inside AMD Software you can enable the In-Game Overlay so you can see if AMD RSR is enabled when a game starts. (the shortcut key is alt + r)
