By the way, the fix for this issue disables vsync which screws up other things because Skyrim was coded for consoles and can't handle fps over 60. It seems like mouse lag is also based directly on framerate as a result of the console-centric coding. Therefore, this fix may not actually work if your computer isn't capable of rendering the game over 60 frames per second. But the bigger issue is that if you can run the game higher than 60 (which a decent computer can do using this fix), you will then end up with a bunch of other problems, such as the one mentioned in this thread: http://steamcommunity.com/app/72850/discussions/0/846959998110492629/ As well as apparent issues with crashes, physics glitches, issues with how time and events are handled, and more. This is ridiculous. If anyone knows of any mods that can let us have the best of both worlds (no mouse lag + everything else works fine), please let me know.
