Penumbra: Overture Haptx + ATI glitches!

[atiwoes]

So I'm experiencing the glitches that I believe are fixed by the ATI hotfix. However, I have the HaptX edition of the game and the hotfix simply crashes when I try to run it. Is there a different hotfix for the HaptX edition?

The glitches I'm getting are texture related, they'll be stretched or duplicated and flickering. For example, in the first room, the map on the table flickers or only shows part of itself, and the portholes are either skewed or become very tiny and numerous. When I have other effects on, such as motion blur or depth of field, there are even more graphical glitches.
