Using the Acer XB280HK 28-inch 4K Monitor - 4K G-SYNC is G-LORIOUS

Gaming With 4K G-SYNC


This is where things get good. I didn't expect too much from the XB280HK in games, as I was so used to high refresh rates. Before having the ROG Swift PG278Q as my daily driver monitor, I was using a 1920x1080 display with 120Hz. The shift to the 2560x1440 display was night and day, especially with G-SYNC, so the move to the XB280HK is a step down in some respects, while a big jump in others.




The increased resolution looks mind-blowing in Battlefield 4, which is something I play a lot of recently. For the first 30-60 minutes, the adjustment was truly hard - going from ~120-144FPS minimum, to a ceiling of 60FPS was one of the harder things to get used to.


After the first hour or so gaming with 4K at 60Hz, I began to actually enjoy it. I lose that 'but it's not 144Hz' feeling, and sank my eyes into the beautiful image that is 3840x2160 being rendered in front of me. It was actually better on my GPUs than the 1440p 144Hz setup, as it's easier for the two GPUs to hit 60FPS minimum - making G-SYNC even better - than it was to hit 144FPS minimum.




This is where the biggest improvement for me laid, was in the fact that an SLI system is much more capable of driving 3840x2160 at 60FPS minimum, than it is at driving 2560x1440 at 144FPS minimum. 144 frames per second is incredibly hard to render for multiple reasons.


First, games these days are hitting around 60FPS max, because they're built around the consoles. This is an inescapable problem, with game engines themselves being built for X field of view, Y hardware (consoles, so multi-GPU scaling is quite poor in games like Battlefield 4 and Watch Dogs) and Z control methods (console controller at whatever distance away from your TV).




Without going into an entire editorial on the reason I hate console gaming and how much they've infected PC gaming, taking it over and pillaging it like it was meat on a dead animal for profits, we have to deal with it. This is where driving 60FPS is a better alternative, and why I found my experience with Battlefield 4, at 4K and 60Hz with G-SYNC, actually quite enjoyable.
