DPC Latency Issue

[radstar88]

I have been having Stuttering Audio the last few weeks. I couldn't pinpoint what was causing it. After doing some research I found i may have a DPC Latency Issue. So i downloaded DPC Latency Checker. When ever FFXIV is the Active window The Checker Hits Red saying there is a problem. Not sure what to do next? I havent changed my hardware since before beta so im not sure why this would start now.

I Figured if I limit FPS to 30 the problem stops.

uggh.. it's a tricky one to chase down. Sometimes you get lucky with driver updates, once you can narrow down which one is bogging down the calls. All the things we install on our systems now... timing for all those IRQ's... amazes me how things just don't throw up on themselves.

Wonder if that advanced timing control option they started supporting in the post XP OS's might help somehow... forget the name of it. Think my old PC had the option, but never used it because it was an XP box. Will have to poke around and read up on it to see if it might be worth looking at. Have to go get in car line to pick up the taru though... something to research later tonight.

High Precision Event Timer (HPET)

couldn't remember the name to save my life...had to boot the dinosaur to look for it in the BIOS. Listed under Power Management on mine, but it could be elsewhere in other systems (if it's an option). May just be an on/off option, or you may see 32/64-bit options. Obviously, don't use 64-bit if you have 32-bit Windows. 32-Bit should be safe for anything from XP forward, but you might have to get updated chipset drivers from your manufacturer if it doesn't auto install them. It should show up in Windows under System Devices in Device Manager if it is already using it.

Not saying it's the root of your problem, or your ultimate solution. But in theory, it may smooth things out a bit as it was designed to help streams synchronize better. It's a much higher resolution clock than the older RTC method. Think of it like clocking racers using the second hand on an old wrist watch versus using a stopwatch that can break it down into hundredths of a second. The much tighter intervals provide closer gaps in the clock cycle to more accurately synch multiple streams.

Ultimately though, it may call for a driver fix. If you've recently changed drivers, it might be worth rolling back to see if it resolves things. If you've recently installed new hardware, that may be supect too. USB and IR devices have been known to do weird things with other games in the past--something as seemingly innocuous as a new game controller could be behaving badly if it is using a custom driver or some sort of button management service that runs in the background.

Just spit-balling here...trying to jog your memory to see if maybe you've overlooked a recent change to the system that you might be able to undo.
