Yesterday I started playing The Elder Scrolls III: Morrowind again thanks to it coming to backwards compatibility on Xbox One, and the first thing that struck me while playing was how much smoother it was. Sure the bump in resolution up to 1920p (on the X) made it seem like I was wiping a thick layer of Vaseline off of my TV screen, but on the original Xbox the framerate would take massive dives, so that it seemed your character was trudging through molasses.
I was shocked to find out that the Xbox version of Morrowind was targeting 60FPS, even though it almost never hit that mark, sometimes dipping down in to the teens, but the Xbox One does a better job keeping things above 30FPS, and the Xbox One X almost manages to keep things at 60FPS despite pushing out more than 16x the pixels and adding 16x anisotropic filtering.
The game still looks dated, and it makes me want to find a way to push out the draw distance because everything is popping up like ten feet in front of my face, but game is still fun, and I find myself getting lost in it again. There is something about playing Morrowind on a console that just makes me happy. Below is a video comparing the Xbox One X, the Xbox One, and the original Xbox. It is pretty impressive to see what Microsoft has done by just tweaking their emulation.
