The most recent demo for the most recent version of the game. The most important change is a rendering fix for new ATI cards and drivers.
Frictional Games has recently fixed some very important rendering issues with new ATI cards and drivers. They are so severe that we think it is important to have the original demos for our two games updated so that the users won't be met by a half-functioning game. The updates also includes other fixes like crashes on certain configurations or even new solutions to some puzzles.
