Ok Trying to run Oblivion on a Phenom X2 550, Ati Radeon 4870 1GB, 4 gigs duel channeling gskill ram,Corsair 750 Watt powersupply (7200 rpm Hardrive defraged). I can dramatically lower all settings to get it to run 50ish fps. With everything maxed on 1920 by 1080 it runs 10-15 fps. I've tried every possible tweak guide and mods I could fine and boosted it up to 20ish (though in cities drops to 10 no matter what). It is filled with lots of mods and if I disable them all gets up to 25ish FPS. Also it appears to only be using around 44% of the processor? Also video card/processor don't even slightly run hot... maybe luke warm...
