Problem with Audio out of sync for NPC's
i only have just started the game and have noticed that any audio when talking to any NPC's is out of sync with the mouths of the characters and the dialog overlaps itself, i've looked for solutions but haven't seen anything to help me so far. please help lol

A too high frame rate can cause audio dialogue getting cut off. This is the most common cause. Limiting the frame rate to 60fps fixes it.

Another problem is with audio over HDMI. This is a rather tricky one... When the audio stream over HDMI gets suspended or sleeps, can it take a moment for a display to wake up its audio. As a result does audio over HDMI occasionally experience sync delays. Easiest fix is to use on-board sound instead.

Since im using a display port it would have to be the FPS. how do i set the fps cap. i looked through the setting in both the launcher and the title screen setting and can't find it. am i just overlooking it?

HDMI and DisplayPort are more or less the same thing, only DisplayPort being a bit more advanced. It, too, can suffer from the same problems as HDMI. But try the fps cap first:

Set your monitor to 60Hz or 120Hz and leave vsync in the driver to "application default" and disable any frame rate limiter. The game should automatically adjust itself to either half or full refresh (this behaviour is new with the update!).

-or-

If this fails or you simply do not like it then one can also force vsync in the driver settings to "fast" (Nvidia) or "Enhanced Sync" (AMD), which turns vsync off but still avoids tearing, and the one needs to limit the frame rate in the driver, too. Both Nvidia and AMD have features for this. Your game does however need to be running in fullscreen-mode for this to work.
