I play on a Macbook Air with 2.2 Ghz Intel Core i7 and Intel HD Graphic 6000 and up untill earlier this year, have had no problems whatsoever. However, after the 1.3.7 patch, the game’s been super slow. All the buttons and interfaces lag, as in they take a few seconds to light up after mousing over. Also, I can’t even play because the game just crashes whenever I login. Because of this, I can’t even provide screenshots, but I do have a log after the crash. It is essentially the same problem as in this thread:
Turn your graphics settings right down to zero. The best you can really do is enable depth of field and a few lighting effects, but most MacBooks won’t be able to handle the insane graphics because of the low RAM… unless you have something around 8GB.
Insane graphics. The GPU is designed for rendering!
