A new video has been posted on YouTube, showing some gameplay of the Battlefield 4 Open Beta in a (higher than) 4K resolution. The resolution by which it is played is 4800 x 2560, which is achieved by using three 30" 2560 x 1600 monitors in a portrait Nvidia Surround setup. Do the math -- that's 12.3 megapixels!
To bring enough juice to the displays, a total of four EVGA's GTX Titan SC's have been used in conjunction with an i7-3970X clocked to 4.8 GHz, as well as 32 GB of Corsair Dominator Platinum 2133 MHz memory. All of the in-game graphics settings have been maxed out, including the Anti-Aliasing settings. According to the description of the video, a total of 5.1 GB of graphics memory was used.
The recording itself wasn't done at the 4800 x 2560 resolution, but rather at the 4K resolution (4096 x 2160). On YouTube, it can be viewed in its 'Original' quality, though beware, you'll need a hefty Internet connection and system to be able to play it, not to mention that you won't be able to see the full beauty of it without a 4K monitor.
