Have video card, onboard sound, usb controller, and nic all sharing IRQ 11. When I added the USB card to my system, my 3dmark scores dropped 1200 points! Using Win 2000 and I found device manager/resource manual controls are locked. IRQ's 5 and 7 are both free. I tried swapping PCI slots and nothing changed. SO I was looking for a way to fix this and found:
1) Reserve the shared irq through bios and see if that redistributes the devices to new irq's.
2) Disable ACPI in bios and format/clean install OS.
I'm going to try these fixes tonight and see if I can get my 3dmark score back up. Hope this might help some other ppl with Win 2k or XP having too much IRQ sharing/inefficent AGP.
