16ms crackling but DAW saves #187
Comments
There are several reasons that will lead Rocksmith + RS ASIO to be unable to achieve a buffer as small as other native ASIO apps.
The only thing that could be done to help this a bit would be to move the processing of the audio to different threads to avoid blocking the ASIO streaming thread. This wouldn't be a very simple task, and it's hard to say if it would help at all. |
Since I am weak in English. I didn't understand much. But the bottom line is that if before starting RS with RS_ASIO, you start any other application running on ASIO (DAW, BIAS FX etc), then rocksmith will be without crackling. |
Oh, I see what you mean now. This is weird indeed.
You can check
Look for |
So, its says 16 frames, just like I set in my asio driver and daw (48 khz - 16 samples) |
It looks like I hacked the system. |
Very weird. The log does have the buffer underrun messgaes, so you should be having sound issues. In any case it's odd indeed that you get better performance with the DAW running in the background. The OS may be doing something that creates a better environment for low latency audio. Perhaps it's the CPU scheduler behavior that changes or something. It's hard to tell. |
Another riddle for which we will never get an answer) And what should I do now? Run any daw before playing? |
This is what will always happen when we're working with closed-source software unfortunately.
You're probably focusing too much on numbers. A 64 sized buffer is 1.3 milliseconds already, it's unlikely that going for 16 will make a big difference in your playing, specially when we already measured the big chunk of latency coming from elsewhere (like the game and the USB stack etc). If you enjoy the game with a 64 buffer, I would say that going through the effort of opening the DAW to play at 16 is not worth it. |
I'm here for same quest for holy grail of 16 samples buffer my system capable of, but RS being willy-nilly and running 128 out 64 in buffers. Through, compiling with all possible /O flags and enabling avx2 extension helps a notch (forcing 48 buffer but it still logs as 64). I find interesting you've got decent audio, since it's not exclusive asio and pre-setup from your daw rsasio shouldn't be able to alter it's real configuration. If it is rsasio mishap we could fix it (assuming it is), but if it's Rocksmith being weird (Im sure) we may need to debug rocksmith behaviour? |
I have noticed when I launch game at 64 samples, its good, but when 16 samples - its crackle. But when Im launch my daw at 16 sample asio before RS with asio, there is no crackling.
So why is that? RS can't start asio for full power or what, or DAW just prepare asio engine?
