I think its dependent on the mouse as well as the new features in Windows 8.1. I have played a lot of games since 8.1 (preview and had the official a week before release thanks to Technet) and none have had this issue.
I have a Logitech G600.
A friend of mine had the issue in 8.1 but he has a Razer Naga 2013. He also said their driver system is pretty bad since its cloud based.
I have a MacBook Pro portable notebook where the screen is attached to the keyboard and it folds in. I run the Windows inside my OS X and have found I don't get the lag. I do have a problem with my photo program changing where it saves my pictures can you help me find my pictures in my MacBook Pro portable computer system?
Mean while Linux side of the house reporting clear skies and smooth sailing with slight breeze and temp in mid 70's. LOL Businesses have not moved off Windows 7 for reason and only reason why I have Windows 8 at the house is because the computer came with it. Couldn't downgrade to W2K7 . Windows 8 is still beta anyways IMO.
