graphics stutter

graphics and sound stuuter with geforce 6800 card. with the card disabled there is no stuttering. I am tired of trying to fix this, ther are no conflicts or irq sharing. should i just get another graphics card? anyone else have this card, working well with scope or no?

I think the type of gfx card is not the problem.
are you completly sure you don`t have IRQ sharing...

- Did you try to position the scope card(s) into another slot...?
- Did you install the 6800 before or after the Scope card?
- Do you have the newest chipset drivers for your motherboard installed?

Thank you for the reply. I do have some sharing going on but have disabled things in an effort to help. Graphics card geFORCE6800 shared with Intel(R) 8201FB/FBM SMBus controller, -2660, Intel(R) 925X/XE PCI express Root Port-2585, and Broadcom Netxtreme 57xx Gigabit Controller. Yikes. I am happy to disable the first two and have done so (even though i don't know what they are) and it has not helped the situation either way. but would like to keep the machine on the internet so have left the network adapter alone

Pulsar2 card shared with Intel(R) 82801FB/FBM USB universal host controller-2526A. I am happy to disable the usb and have done so.

Pulsar one card shared with another usb controller, also disabled.

I have moved the cards to different slots but this configuration seems to have the fewest shared irqs, and is the only one where the graphics card is not shared with one of the pulsar cards.

The graphics card is always installed before the pulsar card in the way i am used to doing installations. I have tweaked its settings many different ways, to what i would think would use the least amount of resources, etc. It its difficult to think it is not the graphics card since when i disable it the problem goes away....

try reinstalling the card's driver, maybe there is a later one. i've always had very good luck with nvidia geforce cards, never a problem. perhaps yours is damaged(i doubt it but it's possible). the sharing you reported should make no troubles as long as you have disable the usb controllers sharing with the scope cards.

What version of direct x are you running? If you run dxdiag.exe are there any errors? With latest graphics drivers it's always best to have latest direct x version.

please look in the manual of your mainboard...

I remember something there are so called virtual IRQs. So while under windows it may look like you have different IRQs the mainboard internally is still sharing the IRQs.

Its some kind of workaround for the fact that newer PCs have much more devices...

btw is your graphics card an AGP type?
