As Fast As Possible
GPU scaling is a feature that allows many AMD graphics cards to effectively scale the image so that it fits the screen both vertically and horizontally. It is particularly useful when playing older games with a native 4:3 or 5:4 aspect ratio on a new monitor which has a more popular aspect ratio, such as 16:9.
If you are using a monitor with modern aspect ratios such as 16:9 or 21:9 but want to play older games which are based on 4:3 or 5:4 ratio, GPU scaling will allow you to choose whether you want the image to be stretched, have black bars at the sides, or have a black border all around the screen.
Some old-school FPS gamers prefer to have a stretched picture as it makes their targets larger and easier to hit, while the deformed image quality repulses others.
Other players might prefer black borders on the sides of the screen as it makes them much more focused. It’s all up to you, and AMD’s GPU scaling feature provides you with the ability to choose.
How to Enable GPU Scaling
In order to enable GPU scaling on your system equipped with AMD Crimson (or later) software and a compatible AMD graphics card, follow these steps:
- Open your AMD Radeon settings
- Click on ‘Display’
- Find GPU Scaling there and enable it
Types of GPU Scaling
There is also a setting called ‘Scaling Mode’ which you can use to decide how the image should be scaled:
- ‘Preserve Aspect Ratio’ will, just like it says, preserve the aspect ratio and add black bars at the top and bottom, or at the left and right of your display
- ‘Full Panel’ will stretch the image so that it fills the screen entirely. The image might look weird as a result of this because it’s scaled from a different aspect ratio
- ‘Center’ will center the image on the screen and put black bars around it. This is useful if the image is smaller than the screen’s resolution
Effect on Input Lag
GPU scaling will add a bit more input lag because of the extra processing.
This is usually just fractions of a second, which is insignificant in videos, but it might be visible when playing games.
Gaming monitors used for competitive gaming should have the lowest input lag possible. Therefore, you must decide if GPU scaling is worth it in this regard.
