This is a bad sign, the slowdown is expected since the driver is continuously looping
waiting for the registers to become available. Did this PCI card work in the past, and
if so with what driver?

Does this card work on another PC, or does the windows or legacy driver work with
this card?

(Yes, all suggestions above imply suspicion about the hardware itself rather then the driver)
