I downloaded the recent Nvidia driver for Bioshock Infinite, and now whenever I try to start up Oblivion I get this message in a little window: "Failed to initialize renderer. NiXAdapterDesc::GetDeviceCaps()failed". The only info I can find about this error is a microsoft support forum from 2009 which hasn't really been much help.
If you downloaded the driver, would you mind trying to boot up Oblivion and reporting back if it works? And if you know how to fix it, I'd gladly take an answer!
(I wasn't sure if this should have went specifically in the Oblivion forum or not.)
