Hi, I'm gonna go straight to the problem: Whenever I change the sliders in the in-game Options (Visual) they immidiately reset their values, for instance: if I change the Grass Distance, and press OK and continue playing normally, it resets the Grass Distance to some value I haven't set it for. This is really annoying cause my PC should run Oblivion at max, and am unable to do so because of this.. Any ideas what the problem might be?

Do you run Streamline? The Streamsmooth feature adjusts graphic settings on the fly to improve performance. You can disable it or adjust the settings in the ini. Just read the readme.

Thanks Phitt, yes I run Streamline, that must be the problem.
