ooh sorry for not replying back guys!
okee, my psu is an enermax liberty 620.
Oke guys this is getting very frustrating!, I am playing 1680*1050,
and this time i have maxed EVERYTHING, forced AA through nvidea software, AF! plus HDR. am getting about 10FPS, outdoor.
Something is not right?
One of the main reasons i went for a 8800GTS 512, was to max out oblivion!
If i had known so i would of gone, for the 3870X2 or 9800GX2
Sounds to me like you bought an 8600GTS.
Just kidding. What level of AA are you forcing? To be honest, true max details 4xaa/16xaf will be a stretch for your card. it should be playable, but you will expereice some low fps. I was an oblivion nut and have benched it to death. In some PM discussions of results with an 8800GTX owner I was told even the 8800GTX can struggle at 16x10 truedly maxed details and eye candy. This can be made worse with mods.
Can you capture a screenie with fps posted as an example? Also maybe a screenie of the map location so others can try the same game area. I'll try a single and dual 8800GT in that same area.
I think you should try 16x10 max details with no aa/af forced. See what framerates you are getting at both those settings. Enable 16xAF and test again. I can tell you with a stock clocked 8800GS, at 1600x1200 4xaa/16xaf, I can reduce the fps in waste high foliage to about 18 fps average, and not during combat even. Also, with an X2 5600+ at stock, I can reduce it to 12 fps minimums in cpu limited areas of the game, again not even during combat. Your system is better than that by far, but you may still be asking too much from it to not find some areas of slowdown. If it is widespread low fps, then something is wrong for sure. Do your fps start high and then suddenly go real low like a VRAM leak? At one time that was a problem with some NV cards/drivers in Oblivion.
