Have you read this (automated?) answer from Ubisoft?

No room for PS 2.0 in this answer... :-(
EDIT: For those interested, the V1.01 patch does not change the single player EXE, and works fine with the unprotected file.
Among other things (at a quick test) the patch adds a AA-option which looks VERY good along with HDR. :-D
Also the framrates seem alot better. This is a good patch indeed. :-)
