From Digital Foundry: “The Master Chief Collection for PC adds another classic game to its ranks – and the arrival of Halo 3 brings with it terrific performance, the best support yet for high refresh rate gaming and even some nice enhancements to existing games in the collection. Beyond the fact that a genuinely great game is now available to PC gamers, what I particularly like about this release is that running it at 4K 60fps actually gave me a much better appreciation of some of the original game’s technical achievements – elements that were hard to spot in the sub-720p Xbox 360 original.”
