Radeon HD 7420G IGP 

If your game is rendering at 40 FPS, lower than the minimum VRR window, then you will again see the result of tearing (with VSync off) or the potential for stutter and hitching (with VSync on).

But, this method requires a local frame buffer and requires logic on the display controller to work.

It is very difficult to capture this on video in a way that will be easy to see on playback, so I broke out the flicker testing gear we developed for our earlier testing on the ROG Swift.

This laptop was equipped with a 1080p display, making that a bit difficult but not impossible.

Nvidia G-SYNC will eliminate annoying screen tearing and minimise display stutter, but of course it will only work with Kelpler and Maxwell cards.

The display is available at Micro Center for $449, which sounds very steep for a 1080p 24-inch panel.

In fact, 4K might be the perfect resolution for G-Sync to shine as running games at that high of a resolution will definitely bring your system to its knees, dipping below that magical 60 Hz / FPS rate.

But when it does with this modified panel, you'll still get smooth game play and a a tear-free visual experience.
