Found a tool on here posted by Frodo I think that could change the pci latency settings etc, as I have a PCI-E vid card it was no good to me but it may help in this situation where you can force the graphics card to have lower latency.
Might be worth a shot, I run a 7300gs passive PCI-E and have no stuttering, think i have HW acceleration turned on, I will check when i get home.
My main problem is blocky pixelation with TV but I think that may be temperature related |
