HELP!! BIOSHOCK AND 3870!!!

i just got my HIS 3870 today and when i started up bioshock, the performance with the 8.6 catalyst drivers wwere worse then my 8600gt's performance... what am i doing wrong cause this cant be right....

please reply!!! i wanna play bioshock without lag!!!

thankyou all!!!

i play at 1280x1024 and i am getting as low as 11 frames at the intro part. what drivers are you using? and it was tempting to go for the 4850 but i didnt have the money at the time.. my next upgrade probally ; )

Obvious software issue.

Did you correctly uninstall old "Nividia" drivers.

You should be getting over 60fps with 3870. 3870 is actually very fast for this game because this engine relies on shader which 3870 is equal to 8800gt if not better.

There's nothing wrong with 3xxx series. It might not perform well as 4850 but it also cost cheaper.

I'm with Marvelous... Gotta be your software: I played all the way through Bioshock on a 4400+ and a X1950Pro @1440X900 without so much as a hiccup... and the game absolutely screams on my HD3870 (Cat. 8.5 and 8.6)...

You in Vista or XP?

I'd the same problem though with different cards.... just uninstall the Nvidia drivers and reinstall the ATI drivers...should work fine. Cheers.

What settings did you activate in Catalyst Control Center (AA/AF)?

Uninstall Nvidia drivers
Uninstall ATi drivers
Use DriverCleaner Pro (google for download) to clean 1.) Cab file 2.) all ATI and Nvidia drivers
Reboot
Reinstall Cat drivers

ok, i just did everything that Vokofpolisiekar suggested and it seems to be running smoother but i still cant get my catylist settings on max without getting super low framerates.. and btw my OS is XP

and what about the otehr settings? ccause it seems more like image quality one really makes a differance going from performance to quality. i have to set it to opptiminal performance to get those good frames around 60-80.

Ive read somewhere the Unreal 3 engine dont like the cats with CCC...

try to download the stand alone driver without CCC.

please check your .net framework version as well.

Glad to hear you made some progress. As a guideline, use CCC in balanced mode and do not adjust AA and AF in CCC. Rather let the game you're playing do the post processing techniques like AA and AF sould it support it (most new games do it).

With older games which do not support AA and AF you can run out of CCC.

Lastly - adjusting the CCC slider I think includes MipMap settings which can degrade visual quality. If you have to go the CCC route, do settings individually and with incremental adjustments, always checking the performance before proceeding. Leave HQ AF for the last. And remember that no one game is the same. Some might run 8xAA and 16xAF while another would crawl at such settings.

??? are you dense?

38xx runs Bioshock well if not better than a lot of cards. Some of the settings need to be be right but it runs great as long as AA is set low. No its no gtx280 or 4870 but hey its still not a bad mainstream card.

No sadly 3xxx improved a few other things but the AA performance was not updated till the 48xx series. This is mostly due to them having to change the way they designed the RV600 chip vs just a simple fix.
