I've just ordered a 13" MacBook Air 2013 and am looking forward to using the device for some light gaming.
I thought it would be useful to make a thread collating the experiences of users here in various games. Please state which OS you are in (OS X or Windows, with gaming performance of course much much better on the latter), your specs, the game and it's video settings and the FPS and/or general gaming performance you get.
Remember that on certain resolutions and games like FarCry 3 ran on medium at about 15-25 FPS on the previous Intel HD 4000 Airs and the HD 5000 is touted as being a significant improvement. If it turns out we can run FC3, BF3, Skyrim etc. on half decent settings on the new Airs then I think that will go down as a watershed for the line...
But on the other hand we could still be **** out of luck. Let's see...
Let's try and fill this list in with results:
FarCry 3
Bioshock Infinite [FPS Drop Fix]
Battlefield 3
Team Fortress 2 - 50-80fps on all max settings (vid)
Black Ops 2 - 40-55fps on all max settings (vid)
Sim City
Star Craft 2
The Walking Dead
Europa Universalis
Deus Ex: Human Revolution
Skyrim
Civ 5
Portal 2
Dead Space 3
Crysis (the original)
Don't forget MegaVolatic's 6 Ways to Boost Gaming Performance on the Intel HD iGPUs. These steps can give you between 10-20 additional frames per second during games (Windows only).
That doesn't look like light gaming to me.
Either way, good luck with it, if you make the purchase.
Don't know the settings on that youtube video but the frame rate is definitely good.
