I have a very odd problem with TESIV: Oblivion. The usual complaints - slow framerate, stuttering and pausing, inventory takes forever to open,

The problems all go away when I install new Forceware drivers... until I reboot the computer.

I've tried clearing out and reinstalling Oblivion, I've tried removing mods and so on; no joy. The only thing that works is to install either Forceware 275.33 or 275.50 without rebooting, then play play play, and rinse and repeat the following day. Any ideas gratefully received.

Without full information, anything suggested is nothing but a WAG. Personally, I don't believe in those.

What other info would be needed?
