48khz sound stuttering/performance

I always recognised some very hard stuttering within some games using wine and I found out this is caused by the sound-implementation of FreeBSD.

To be specific:

48khz sample rate means no stuttering within grim dawn for e.x.
192khz sample rate means very hard stuttering within grim dawn for e.x.

I wasn't able to test this on all games yet but I assume it's a lot more games or even all games being affected by it.

This thread is opened to inform about this issue.

I agree. As it stands it's likely going to be ignored or closed.

Mixing is done on the CPU, 192 kHz is obviously 4 times (192 / 48 = 4) more resource intensive than 48 kHz.

Changing kernel-behaviour to always choose the last cpu/thread for soundprocessing should solve this.

It's hard to believe to me that soundprocessing is causing that much impact on performance.

Well with that comment, I'm sure everything is settled and someone will fix the kernel </sarcasm>
