I have a 3.7+ghz, 1gb ram if not more, lot free space, and a nvidia 6200 se turbocache and i need to play it at 800*600!! Tomorrow im going to buy a 7600 nvidia GS!
i run this game on 800x600 medium ranges on trees n grass no aa full view distance almost half specular distance and im running on a nvidia geforce 6200 xfx 256mb a intel celeron 2.7 ghz processer 512mb ram it runs perrty decent kinda jumpy at times when im outside try defraging ur harddrive i suggest u clean ur regirstry scan for viruses n also turn off virticle sync that really bogs down my system but over all i can run it perrty well for such a low end system 2 tell u the truth i can run it with aa x2 and its still enjoyable 2 play
i'm using a ge-force fx 5700 ultra, and it blows away the ti 4400. however, for oblivion i have to run it in 640x480, set everything to low except the textures. lights are the only that really get to me in that game. it's terrible.
Upgrade to a nvidia 6800 atleast than u should see a very nice boost.
or a 7600 GS or GT or higher...
tUrN oFF ThE GRa$S And Get The Coolbits Registry Tweak (you Know the frames to render ahead one).
Lots of tweaks (including that one) here:
I've Got A Crappy Card Too (Geforce 6600LE) And Im Running At 800x600 With 4 x Antialias with most effects on (exccept shadows) Just From Doing Those Two Things.
This Will Make The Game Run Much Smoother
