The vid card is in an AGP slot. The slot next to it is 1 of 5 PCI slots

The 1st PCI slot shares the same IRQ as the AGP slot
This causes problems in some XP machines when
you are playing Medal Of Honor

I had the same "Stutter" on my new Dell box as
MeatGrinder did - mine was not as bad

The problem cleared up 100% on both machines when
the slot next to the vid card (AGP) was cleared out

Once the 'puter was rebooted, XP re-assigned IRQs
and in both cases the vid card was on its own IRQ
where as before it was sharing an IRQ with the 1st PCI slot

Even though shared IRQs in XP are not a problem this was
a problem for this game - no other problems were encountered

Yup... ripleys believe it or not

Well, it got a new DMA channel (these are hardwired to the PCI and AGP slots, there is no 'reassigning' these). The IRQ's don't matter in XP or Win2k - the HAL takes care of all the direct hardware access anyway. The OS doesn't access hardware or give hardware time using IRQ's anymore. It's a legacy thing now.

Like anything in the PC world, it's a trade off for supporting new technology while still being 10 years backwards compatible. oOo:
