Recently upgraded my computer, old was i7-4770 and new is AMD Ryzen 7 3700X. Bit more cores and bit better single core performance, but main point was moving from SFF to full size so I can have real gpu and more hdd. Old was running debian 11 based devuan, new debian 12 based.
For some reason, in new computer Bitwig is having hickups. It freezes durin playback/recording for short time, causing bunch of xruns. Jack itself runs ok, same time my guitar audio from interface to non-mixer and output works without any problems. There is no shortage of cpu, over 90% of cpu is idle. rtcqs only complaint is 'Kernel 6.6.12-1-liquorix-amd64 without 'threadirqs' parameter or real-time capabilities found' and meltdown mitigations. There is plenty of other programs running all the time, but closing them is last resort. My music making sessions can be sometimes very short, and if I would close all dozens of programs and then re-open them and put them to correct places in my multimonitor desktop would take some cases more time I am going to spend for making music.
Things done this far. All these seem to help a bit, but problem still exists
- change plugins in bitwig to run as separate process
- renice all other remarkable programs when making music
- renice -19 all bitwig processes
What else I could do?
