If you suffer from dropped frames (not due to the user application being simply too slow or processor being waaaaaay too slow) then there must be a PCI settings or IRQ settings issue. It has nothing to do with cpu load or disk activity. Try setting the PCI latency for the video card to maximum and for all other devices to the mininum. This will prevent your disk controller eating up all bandwidth on the PCI bus. Also check that your harddisks run in DMA mode.
