Hello,
i have the following problems with tiles. After uninstalling tiles, the problems are gone.
Short system description, as it may have to do with it. This is a 3 Monitor Windows 7 x64 setup with the latest ATI drivers.
1. General mouse lag, when running games, i.e. Skyrim or Modern Warfare 3. Quitting tiles solves the problem.
2. Overlay Video Freezes, when running tiles. In this case I was running TV or Video files on another monitor. after some time the picture freezes. Quitting tiles solves this problem. TV and video are rendered through EVR.
