The remaster featured high-resolution textures alongside other visual improvements such as new shaders, volumetric lighting, and a dynamic depth-of-field. Skyrim Special Edition came out in late 2016 as a 64-bit version of Skyrim, running on an updated version of Bethesda Game Studios' Creation Engine.
It's more than just a graphical upgrade, though: a fact that helps to distinguish it from the last Skyrim rerelease, Skyrim Special Edition. The game will be a next-gen upgrade of Skyrim and is set to release on PC, Xbox, and PlayStation consoles in November 2021. To mark Skyrim's tenth anniversary, Bethesda is re-releasing the game yet again in the form of Skyrim Anniversary Edition.
