Hi community,

I am having performances troubles with bitwig. For instance, while playing the "ModeAudio Demo Song", the intro is ok with the drums etc. but when the pads starts playing the audio gets really bad, crackling, slowing down and the dsp meter becomes crazy.

Is my computer too old for bitwig or is there any good configuration things to do ?

I'm using ubuntu (12.04 - 64 bits) and my old computer have these characteristics :

  • Intel® Pentium(R) Dual CPU T2390 @ 1.86GHz × 2
  • GeForce 8400M GS/PCIe/SSE2
  • 4GB Ram (it looks like the ram is enough but my CPU is too slow)

Have you any idea how I could make it works better ? I have tried various samples rates up to 1024 and it has not change the problem.

I have searched and I wonder if things like these could be the solution to my problem :

  • tune settings for swap (can we set bitwig cache in ram ? or thing like that ?)
  • use jack (will it change the game here ?)
  • change graphical environment (like openbox ? will be good for ram consumption)
  • use an other kernel (I have heard about realtime etc. but never tried)
  • force CPU frequency (if it is possible?)
  • use an audio interface rather than the integrated one ? (will it change the game ?)

Or I need to change my computer. (It is an old one but still working so I prefer not to change it...)

Thanks in advance for the help.


P.S. : I'm planning to use bitwig only with the integrated instruments (no VSTs I am on linux and I prefer not to bother me with bridging windows stuff etc.) also I will record my guitar sometimes.

Hello nibler! The machine is indeed a bit weak but you can try these steps to optimize this a bit:

  • Try a lower sample rate, 96kHz is almost doubling the required amount of computation
  • A buffer of 1024 is the least demanding of the available sizes (No, for technical reasons we cannot go higher..)
  • Definitely use jackd - it brings drastically improved buffer stability and thus performance
  • Another Kernel shouldn't be necessary, but you could probably get some boost there, too, yes.
  • Overclocking CPUs is not recommended, that can cause all kinds of evil timing problems, e.g. USB soundcards failing
  • Changing to another interface will probably help with various issues onboard cards usually have, but will - in most cases - not really help performance wise.
  • Switching to a low profile window manager/desktop system can help a lot, esp. if you have activated all the eye candy modern GUIs come with, but not the necessary CPU power for that ;)

Hope that helps && cheers!

Your machine is not much powerfull, but is fine for the Bitwig.

Use Bitwig with qjack and configure qjack (or jack), sample rate and audio in and out.

If you create a big project with Bitwig, this impacts in the CPU and RAM.

you don't opening programs unused.
