ASUS ROG PG278Q Swift G-Sync Monitor Review

Refresh Rate

Regular readers will have often heard us wax lyrically about a graphics cards ability to output a rock solid 60FPS average, because it allows us to enable vsync without switching from 30 frames per second to 60 intermittently. With vsync on the monitor always sticks to 60/30/20/15 FPS scheme so if you dip to 59FPS you get 30 to ensure a complete frame is output in sync with the refresh. And 30FPS isn’t why you brought your shiny new graphics card. Unfortunately vsync stops screen tearing, which is the bane of our existence, so you kinda have to have it on all the time. What the nVidia G-Sync does is tie the monitors refresh rate to your graphic cards output, giving you the benefit of the non-tearing vsync mode, without the drop to 30FPS when things get busy. 

The really cool thing about the PG278Q Swift is that it can go all the way up to 144Hz, so if your GPU is capable of putting out that many frames per second then you’re going to see every last one of them. On regular monitors any frames above 60FPS are wasted, because your monitor can only refresh 60 times a second. So in short, you get more out of your investment and there is a visible difference too.
