Assassin's Creed: Origins just released, and we have our review in progress discussing the finer points of the game and environments. But what does it take to actually run the game well? I haven't had a chance to test all the hardware combinations I plan on checking, but I have run through nearly all the current generation GPUs from AMD and Nvidia. After the rocky launch of Unity and a year break for the team following Syndicate, I hoped performance on Origins would be better. Unfortunately, like the past few iterations, you're going to want to bring the heavy guns to bear.

For these tests, I'm running Intel's latest Coffee Lake i7-8700K processor on MSI's Z370 Gaming Pro Carbon AC, with 16GB of G.Skill TridentZ RGB DDR4-3200 CL14 memory, housed in Corsair's Carbide Air 740 and powered by a Corsair RM650x PSU. Games are run from a Samsung 850 Pro 2TB SATA SSD, with a Samsung 960 Evo 500GB M.2 drive as the OS/boot drive. The graphics cards are mostly MSI Gaming X models, with a couple reference cards for AMD's Vega 56/64. The complete list of GPUs tested is on the right.
