Audio Latency in Unreal Engine

+2 votes


I've successfully integrated Wwise with Unreal Engine. But there is a noticeable latency between user input and the sound start playing.
The latency is about 80ms when using a normal sound card, which is not huge but definitely has a negative impact on how the gun feels. Unreal native sound system has a latency of <40ms (not measured, just from the feel of it).

There is AkInitSettings::uNumSamplesPerFrame() but is there a better practice for Unreal? I want to avoid compiling from source if possible.

Thanks in advance!

We are experiencing the same amount of latency ~80ms.  Would love some help on solving this.  Many of our weapons just don't feel responsive with this amount of latency.
