Virtual Super Resolution (abbreviated VSR) is an AMD feature available since the Catalyst 15.7 update. You can enable video games to easily and quickly improve the image quality with the tick of a box.
Virtual Super Resolution allows the game to be rendered at higher “virtual” resolutions (up to 4K) than your monitor’s native resolution allows. It then rescales them down to your display’s native resolution.
The great thing is that when you enable Virtual Super Resolution, you can get an image quality that is close to 4K even on a 1080p monitor without having to sink a bunch of money into a 4k monitor. You can see in the video below a comparison in Witcher 3 between 1080p and 4K resolution using VSR. The increase in quality is very noticeable.
Does VSR affect performance?
There is some performance impact with Virtual Super Resolution enabled. With higher resolutions, you can always expect a lower frame rate since you’re processing more pixels. You should decide for yourself whether the increase in quality is worth the loss in framerate.
Should you turn VSR on?
As we’ve said, since the tech makes you play the game at a higher resolution, you will take some performance hit. If you have a supported graphics card and think your PC can handle the increase in processed pixels, you should enable VSR and explicitly see how much it affects your performance.
Luckily this is made easy using Radeon’s built-in framerate statistics feature. You can check this by simply enabling Radeon overlay by pressing Alt + R. The best way to test the impact is straightforward. Run a game, preferably the one you often play, while VSR is turned off and the game is on native resolution and jot down your average FPS. Then turn it on and rerun the same game at 4k. Compare the two.
