With the Xbox One X and PlayStation 4 Pro out now, the continual analysis of how multiplatform games run on both suped-up systems is in full swing. Digital Foundry, a division of Eurogamer known for its tech analysis, took an in-depth look at Assassin's Creed Origins recently and compared the performance and visual quality of the game on both platforms.

First thing to note is that the game uses dynamic resolution scaling; the render resolution will adjust itself in real time based on how graphically demanding the game gets to maintain a consistent framerate. To alleviate the loss in quality, Origins uses temporal anti-aliasing that reduces jaggies while making the overall image look softer.
