This tweak is an important one, and one well worth checking into. Apparently, newer high-end video cards hog PCI latency for no known reason. This makes other components wait for access and causes stutters and lower frame rates. If you adjust the latency, users are reporting big improvements.
Then download this small utility program that allows you set your PCI latency. Adjuste the PCI latency from 248 to 64, and there's a very good chance of stutter free performance & sound.

STEP 1. open the pci latency tool
STEP 2. Rightclick on your graphics card and click change setting(s)
STEP 3. change to desired setting and hit ok
Step 4. click settings and select apply at startup so it has a tick next to it
STEP 5. click settings and select save so everything you have just done is saved
STEP 6. right click on your video card and click quickset latency (if you want to set it straight away).
