Hi, like the title says, i've just installed the unofficial oblivion and shivering isle patches and my frame rate has taken a serious hit! My frames went from 120+ down to now an unplayable 27 standing still in the open world. No other mods have yet been installed nor did it used to have any as i just bought the game on the last day of the steam sale and no changes have been made to the graphics options since last night either, i have checked. Is this to be expected? why? win7 64bit i7 7950 gpu. Any help would be appreciated.
