mastercomsKeep in mind that in some cases, lowering snd_mixahead can actually increase latency because you aren't filling the buffer enough for how much your audio device reads at a time and your own framerate (since the game is not multi-threaded, audio only can write during the frame). Also, I have not investigated if this has changed since the sound system got updated in the 64-bit update, but snd_surround_speakers 7 can also reduce latency due to how it changes how audio is written in the buffer.
I'll try that thanks, also yeah i had no idea about that
