The bug in question was causing fog to be rendered incorrectly in all games based on the Source Engine, the most notable ones include Half Life 2 and its variants. Therefore, the bug was rather annoying to massive amount of people.
We talked with Terry Makedon, father of the Catalyst drivers, and learned that ATI was well aware of the fog bug and it had a priority in sorting out the problem. After using a lot of magic, Mackedon's team managed to squash the bug that plagued games based on Source Engine (and there is a sizeable number of them).
We are still waiting for a fix for World of Warcraft Wireframe bug that happens to owners of 2900XT cards, though.
Drivers are expected to hit the websites around the second week of August. As we all know, ATI is not limiting distribution of its software to preferred websites. µ
