Now that you are experiencing the fantastic CPU savings of vdpau, you
may find that the cpu power saving configuration kicks in.
With the CPU underutilised, the cpu speed drops to the lowest clock
rate, and (depending on your mobo/chipset/cpu) this can also slow the
bus (pci/pci-e/disk/memory etc).
If you do experience stuttering, make sure you turn all power-saving
modes off and retest. I personally
have the cpu's drop to their lowest setting, while a friend finds
stuttering when the cpu speed drops
because their chipset also reduces (throttles?) PCI-E bandwidth.
