hi all
every now and then i hear people complaining here in the list or on #dataflow in irc, that audio is affected (drop outs), when doing some gui stuff in pd on windows. i don't know about osx, but on linux, i never experienced, that the gui was the cause for drop-outs, even if it consumes a lot of cpu power. i assume, this is because the gui-process and the dsp engine are started with different priorities on linux. today i wanted to test one of my patches on windows. it is part of the patch, that a visible array is updated every 100ms. indeed, i got a drop-out on every update, so that my patch sounded like an uzi. turning the array update off removed also the drop-outs. i found out, that 'pd.com' and 'wish84.exe' were running with the same priority, so i set 'pd.com' in the windows task manager to 'realtime priority'. as usual, windows pops-up a message saying that this is dangerous and might harm the system. however, after that i could turn on the array update without getting drop-outs anymore.
i just wanted all the windows user to let know, that there _is_ a way to optimize your pd. probably someone with a deeper knowledge about windows than me knows a way, how to set priorities permanently, so that it doesn't need to be changed in taskmanager after each launch of pd (?).
i tested with: windows xp home pd vanilla 0.40.2
