Amazing Game, Do Not Buy This Version

Do not buy this old copy. It is not optimzed for retina displays, 64bit processing, or El Capitan. It runs very sluggushly on my 2015 rMBP using the AMD Radeon R9 M370X 2048 MB card.

However, the Steam version not only supports Retina screeens but also supports 64bit processing and El Captan. It is a newer version (2.0.0.1 vs 1.0.1) and also runs much better: I average 15fps at max settings on the MAS version, but I get 60fps when using the Steam version.

This game is breathtaking, and as such deserves to be experiance in its full glory. Buy it on steam, not on here.
