When I start Braid on my Retina Macbook Pro, the game will sometimes start normally, and I can play it, but other times only the bottom left corner of the game is visible, and the graphics look really ugly. The same happens with Trine 2.
I don't know when it works or when it doesn't, just that it seems somewhat random to me. Could it have something to do with the graphics cards? Right now my battery is at 100%, and I'm connected to the charger, so I think the discrete card is the one powering the game. Could this be the problem? How do I tell?
Also, on each game's launcher, I select the "2880x1800" resolution.
Here's Braid looking all messed up:
