Games that I had issues with:
Blood Rayne 2 (menu is messed up and graphics are very washed out during the game)
Call of Juarez (shadows - they go all over the place and frequently cover too much of the area and flicker on and off)
Far Cry HDR+AA
Halo
Oblivion (edit: using HDR+AA)
Splinter Cell Double Agent (edit: what happens with high detail shader ON)
UberSoldier
Edit: Since it's not obvious what is wrong with Blood Rayne 2, I included a screenshot of what it should look like in the attachments. Same with Call of Juarez.
