Regarding the first link (PIC latency timer), it says:
"AGP video cards DO have PCI Latency timers. PCI Express cards DO NOT have PCI Latency timers."
Does this mean that the latency on a PCI express card cannot be changed, thus the tool will do nothing? I'm confuseded a bit.
On the other hand, I have an Nvidia 6800 GTO card and was using the previously "latest" driver which was 77.77. This driver sucked. I now upgraded to the latest 8x.xx driver and things seem much smoother. O well...no matter what driver I use I still suck - but at least I don't stutter anymore!
