Why does there seem to be no performance increase?

So I just bought a 7800GS 256mb card to replace my 128mb radeon 9800 pro, and it seems almost like there is no improvement in performance. Oblivion reset itself to ultra high quality, but if still get 25 fps at best outside. even 3dmark seems to be giving me almost the same stuff i got before (from what i remember)

I have the latest nvidia drivers, p4 3.0ghz, 1 gb ram

Any ideas? Am I just crazy? 🙁
 
1. His mobo must be AGP, because there are no PCIe 9800 Pros, and he didn't mention replacing a mobo.

2. It wouldn't matter because the AGP bus is far from being saturated.

3. Did you plug the extra 6-pin power connector(s) in? If the card isn't getting enough power, it will underperform.

Ultra high quality causes a huge performance hit. So does moving to a higher resolution, and you've probably gone from nothing to Bloom or HDR.

Read the AnandTech Oblivion video article to see just how badly this game beats down even the best graphics cards.

There are tweak guides all over the place (and see the Oblivion technical thread in Software) that will let you see most of the eye candy while improving the frame rate.

Did you run driver cleaner, to make sure you totaly rid your install from ATI drivers. This might help.
 
try turning off AA/AF, what resolution are you playing at? did you reformat when you switched cards? i would do that. but first try playing without any AA/AD and turn settings to med-low. nvidia cards dont perform as well in games as ATI with aa/af on
 
Could be CPU limited, depending on 3DMark version. Can't say I know how well a 3gig p4 performs in games, but I'd say a little OC might help some aswell.

This is more if everything turns out to be installed properly etc, listen to other people's suggestions first. 🙂
 
You DO NOT need to reformat for swapping video cards. That's an inane waste of time. Reformatting is like running from the problem instead of actually solving it ><
 
Make sure the AGP bus is actually running at 8x in the bios. Sometimes you pop a new card in and it will default back to 4x or 2x if your board is manually configurable. You could run Sandra Sisoft to check this from in Windows too.
 
Here is the anandtech performance review with Oblivion. You can see that even high end SLI/Crossfire setups were heavily strained with HD or Bloom enabled, with ultra high settings, you probably have at least one of those enabled, and that would be your problem with your frame rates. Not likely anything wrong with your machine or video card.

Lets just face it, although Oblivion is very pretty, the game runs like ass on every computer. Its amazing how adjusting one little slider like grass can double or half your framerates.

Its probably the settings in Oblivion or Nvidia settings.
Make sure grass is turned off since the performance hit is very heavy.
