Despite the complaints that are seen across the internet, the launch of Skyrim Special Edition (on PC) has not been bad. If you received it for free, because you own the original Skyrim and all of its paid DLC, then it delivers a newer engine with more rendering features and the potential to handle much more modded content at the same time. It is a new game, though, and I think users were expecting to binge on it at launch, when it will take a bit of time to catch up to the original game.
Speaking of catching up, though, Bethesda has released a beta patch for the PC version. Skyrim Special Edition 1.1.51 will remove compression on “some” sound files, which was a major complaint that circled the web since release. They also fixed a few bugs with the save games, performance, and NPC behavior.
To access it, switch Skyrim Special Edition to the Beta channel on Steam by right clicking on the game in your library, clicking properties, and changing the drop-down in the betas tab.
