Hi everyone, first post here, this forum and great community already helped me a lot, thanks !!

I'm stuck with this problem:

when i launch puredata, it uses 25% of cpu, which corresponds to one full cpu core (!!!)

I tried with or without -rt, -nosleep, -sleepgrain <1>, blocksize <64>, it doesn't change anything (i use these tags to increase precision in timers, delays and metros)

I tried reinstalling it, i tried it in 32 bits, i tried it in different priority modes with windows task manager.

i tried with pd-extended and no problem! 0 to 2% cpu usage with dsp off, even with fat midi patches...

...but the metro object in it is erratic (skips some beats !), contrary to vanilla's, so i'm currently stuck with a cooking-egg hot and howling fan laptop.

Anyone encountered this problem?
any help would be much appreciated!!

@Rachitic-dada Just downloaded the portable version and opened it in 64-bit win7.
No problems.... so not helpful for you....... unless you do the same and it solves the problem...?
(if you try the portable version then unzip it, open the bin folder, and run pd.exe....... your antivirus might quarantine it and then you would need to restore it from the antivirus control panel).

Control message timing will suffer if audio is not being processed in time (even with DSP off) so try allowing more time (increasing the buffer) in Pd audio settings...... Delay "mSecs"
I have mine set to 80 mSecs for everyday use with the on-board soundcard.
It might not be a permanent solution for you as it will affect midi lag as well, but see if it does solve the CPU problem.
Even the portable version of vanilla looks up the registry settings from previous Pd installations...... so double check that the flags really have been removed when you are testing.
I think -rt is Linux only.
Extended stores its settings separately in the registry.

@whale-av I decided to erase every .reg file out of frustration, and pd vanilla 64 bit works again, taking 0 to 2% of cpu ! metro object sounds precise enough to my ears so i won't try to mess with -nosleep and such. If I come across the right .reg file to erase, so pd doesn't forget every preference, i will up this post with the info. Thanks again!
