Software Description

Utility to set PCI Latency and possibly prevent game stutter or improve FPS.

Attention - this is the OLD download section of Guru3D.com, click here to visit the new and up-to date one.

This version of the PCI Latency Tool is compatible with Windows XP x64. You must be logged in as an administrator for the tool to install. Most devices support latency values which are multiples of 8 (which means any other value will be rounded).

AGP video cards DO have PCI Latency timers. PCI Express cards DO NOT have PCI Latency timers.

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 thus lower frame rates. If you adjust the latency this might benefit you, users are reporting big improvements.

You can download this small utility program that allows you set your PCI latency. Adjust the PCI latency from for example 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).

More information and user experiences can be found in this forum thread.

This is a major update. Most significantly, the tool now restores the settings when coming out of stanby and a really nasty bug has been fixed (The tool didn't check if the devices reported by Windows are actually present in the system, and it turned out some of the reported devices were bogus, resulting in an instant lock-up).

New in 3.0:
-Complete rewrite. Smaller, safer, faster.
-Restores saved settings after resuming from standby.
-Import/Export preset functionality.
-Nasty bug fixed (system lock up due to Windows reporting non-existing devices)
