Really bad performance on my 6800nu

[Darkstar757]

I installed the newest nvidia drivers as well ad Direct X C. However when I run the mermaid demo or the bug cather demo and doom3 my performace is poor. I get croppy frames and in doom 3 on on medium detail at 128-X1024 im getting 25fps. Can someone please tell me what to do to fix this issue. Is it some in my bois etc.

My rig status are as follows

3200+ Athlon
160 gig sata
DFI Ultra Nfore2 Lanparty REVA
512 meg 3200 mushkin ram
Nvidia 6800nu
Antec true power PSU

Is there something in the bios or something causing a problem

Dark, didn't you have an ATI card right before this? Look up Driver cleaner and what not to make sure u cleaned out any old drivers.

 

[StrangerGuy]

And make sure you got the nForce drivers installed.

 

[RacerX]

try (re)installing your nForce drivers

the GART in particular

 

[Darkstar757]

hey guys i believe i reinstall all of the drivers including the Nforce ones

You need to run Driver Cleaner. Just to make sure you get rid of any ATI drivers remnants left in your system and registry. Remove any nvidia drivers as well and reinstall them afterwards.

you're not running duel monitors are you? I was and I noticed a performance issue when playing doom and other games. But once I set it back to single monitor, it ran great.

 

[Darkstar757]

nope single display

i have reinstalled all the drivers and the nvidia demos are still super choppy

I would honestly format and re-install XP.

Teh 512mb of RAM is most likely the problem here. Get another 512mb and you're set.

Make sure you have your AGP aperture size set to 256mb in your BIOS. You could try enabling fast writes. Make sure AGP 8X is enabled.

Try disabling fastwrite. Otherwise, sounds like you need to exchange the video card or rma it if nothing else is working.

No, 6800 don't like fastwrite.

 

[Darkstar757]

ok

Sickbeast is right, it's the AGP aperture for those demos from what I've read.

I'm glad I was able to help you out man. :beer:

 

[Darkstar757]

with high settings im getting 50fps in DOOM 3

WOOOOOOOOOOOOOOOOT

what exactly is the aperature size? just curious.. should all cards be 256?

It's the amount of system memory that is allocated for AGP. If your graphics card runs out of memory it can use your system memory up to the maximum of your aperture.

I use 256mb; I have a 128mb R9700PRO and 1GB of system memory. At one point I even found benefit in setting it to 512mb.

It's hard to make a blanket statement and tell everyone to run 256mb as their aperture. If you have 1GB of ram or more, 256mb should be optimal 90% of the time. With an older graphics card, you won't need as much. If you have a 32mb GF2, 64mb of aperture would probably be fine.

There are rules of thumb which say you should put the amount of video memory that you have as your aperture; others say you should double it. I've found that it depends on the application and how much system memory you have.
