hey gamers, if you're like me then you know of the sluggish feeling of mouse on the mac. it especially hurts when playing games like counter strike: source and team fortress 2 (and i've heard that a lot of people complain playing starcraft 2). Well this man not only deduced the problem (lag, not just acceleration) but he has created a fix for it, namely 'smoothmouse'. here is the link to download, however you do need to join the forum: http://smoothmouse.net/forum/topic/40-latest-version-download and here is his article about the mouse lag http://d43.me/blog/1205/the-cause-for-all-your-mac-os-x-mouse-annoyances i haven't tried it yet on games, only general use. ---------- p.s i can feel the difference with general use, it feels alot snappier. Also you have to uninstall any other mouse fixes you've installed as well as your mouse drivers.
