Title says it all really.

Noticed today I was getting a CTD ("Oblivion has stopped working...") on loading a save game. Tried a bunch of things and remembered that (amongst a host of other programs) I'd updated to the latest Game Ready drivers (358.91) today.

Uninstalled them and Windows automatically re-installed 353.30 from back in June. Oblivion loads fine.

I want to see if I can go back to 358.87, which were running fine for me, but thought it'd be nice to post this in case any other Nvidia users are having the same problem and haven't tracked it down.
