I have a nvidia 9500 gt 1 gb of ram intel p4 2.8 ghz .. i try to run oblivion on high settings with bloom and 2x or 4x anti aliasing and the game runs like garbage the fps jumps way to much from like 40 to 15 back to 25 in like 3 secs .. ive seen alot of you tube vids of people running obliviion on max settings with 9500 gt any help to improve my fps thanks..
