Thank you! But I already tried that. Can't find anyone on youtube who actually plays it on a Macbook Air 2015 (big shock cause youtube has EVERYTHING ;))!

I found this article: http://www.macworld.co.uk/review/mac-laptops/13-inch-macbook-air-early-2015-review-video-3601654/
It's reviewing the new MBA and when you read what it says under the heading "13-inch MacBook Air (early 2015) review: graphics" it seems like you should be able to play Tomb Raider on it, or am I wrong?!

You might not find a video of the exact combination you are looking for and that is not strange since, the game is quite a bit older than the 2015 model you consider. But you can have a look at something close like the previous model:
And then consider, how much better the 2015 should be by checking out reviews.

I am confused by the result in the review you have found, since the new model despite a better gpu is not faster. I suspekt that it not quite a 1:1 comparison and they also wonder if os x 10.9 vs 10.10 makes a difference.

Have a look at the video I linked to and determine if you find that satisfactory. 20FPS from the article is on the low side, but perhaps some tweaking with the quality can change that. The windows version will without doubt perform better on the same hardware, because Apple's opengl implementation is known to be lagging behind.
 
Thanks! I will look into this :)
So you mean that I should use something like Wine to run the windows version instead?
I am confused by the video though. He writes that he has a 1.7 processor. Mine has a 1.6 processor. I thought the earlier Macbook Air had a 1.4 processor...

No, Wine will no get around Apple's OpenGl implementation, neither will a virtual machine. Bootcamp will.

Yes the previous i5 processor was 1.4Ghz, but the i7 version was 1.7GHz (hvis I also have in my machine). The 2015 also has an i7 version running at 2.2GHz.

Whether it is a i5 or i7, the GPU performance is the same.
