Interesting to note you no longer need the Chuck patch for Oblivion.
from the release notes:
"HDR + Anti-Aliasing support for The Elder Scrolls Oblivion - Users no longer need to download and install the Chuck patch - the Direct3D driver now includes native support for High Dynamic Range and Anti-Aliasing with The Elder Scrolls Oblivion. "
