I have been experiencing very slow cursor movement in the menus since the release of TW2, and today i had hoped this awesome new patch would fix it, but alas, it still horrendous. In-game all mouse movements are perfect so i can still enjoy the new arena in all its glory.

Does anybody else experience similar issues (and perhaps found a fix)?

I had the same problem, I uninstalled the game (including registry) and updated my graphics-directx drivers. After that, i installed the game to the part of my HDD that doesn't have windows folder and started to run the game as an administrator. I did all of them above before running the game again so i can't really say which was the solution. Hope that helps.

It could be about lack of memory too, though. If you are running TW2 alongside some other programs, it may cause problems.
