The graphics settings are set to an average of medium-low options. We can see that the Air doesn't have a high frame rate when running StarCraft 2 over the Internet, and it lags slightly when moving around the map; eyeballing the frame rate, it should be around 15 fps.
Call of Duty: Modern Warfare 3
Call of Duty has a huge following as the king of world-class FPS. The video above doesn't mention specific image quality options, and it should still be playable at around 20 fps when running.
Battlefield 3
Battlefield 3 is a graphics card killer, and the Frostbite engine is extremely demanding. The video has all the image quality options on low, and as you can see, the frame rate hovers around 20 at first, peaking up to around 35, which should still be considered playable.
The Elder Scrolls: Skyrim
Skyrim is definitely a highly rated masterpiece and extremely playable. The video has the image quality settings all set to the highest of the sick levels, and you can see that there is lag from time to time, but it's not completely unplayable. It's worth noting that the game in the video was installed on an external hard drive; if it had been installed directly on the Air's SSD, it would have been even smoother.
Big Pineapple 3
Some of the Big Pineapple 3 testing was actually covered in the second half of the Starcraft 2 test. And with the Big Pineapple image quality options in the video above: material filtering: high; shadow quality: low; physics: high, anti-aliasing turned off, and a resolution of 1280 x 800, it's perfectly playable with a frame rate that reaches 40 to 50.
The above are some professional reviews on the internet, testing some popular games, which are still playable. In addition, DOTA and Warcraft, which are more popular among Chinese people, can also be played on the air, provided that the dual system is installed and played in a windows environment.
From the above tests, we can see that Air is certainly not the choice for gamers, but if you don't particularly care about the image quality options, it's still feasible for the average gamer to use Air to play games occasionally to pass the time. In addition, the games tested above all require a relatively high level of performance, so I'm sure you'll have no problem playing some of the more common games on the 2012 Air.
