strange issue (CPU)

[tester]

It appears, at least on my machine, that empty schematic (static gui element only, xp sp3, c2d 2GHz), exported to exe - takes 50% of CPU (i.e. takes 1 core). Schematic itself, in Flowstone - is working correctly. Only exported exe file, in task manager, shows that high continuous CPU usage. Somewhat virtual... What interesting is, this issue does not affects real performance of streams. If I put something inside the schematic, then exported exe works fine.

Can someone confirm? Explain?

Looks like it is not just problem with your schematic. I have tried to export my work in progress synth to exe and result is same. 50% on idle -task manager. No problem on vst export.

Yep, the same with VST here (works fine).

I think this needs to be reported to devs.

Very strange...
I don't see this with my latest project - it is almost exclusively MIDI and Ruby. and no default menu bar. Makes me wonder...
- Something to do with audio, (or audio menu options)?
- Ruby doesn't like it if there are no Ruby prim's?

I think this needs to be reported to devs.

Certainly - I can e-mail Malc directly, but I'll wait until he is back "in the office" tomorrow. Some are affected and some not, maybe a few more people post tonight and we get a little idea what is the pattern. No work for me tomorrow also - I will try a few little tests.

hmm, i tried some different examples as exe export, all with the same result - cpu 50% or more!
never had a close look into exe export, are there some rules which has to be included in an exe?

[trogluddite]

Boy, am I a dumbass sometimes!

Yes, I see the effect even with the schematic that I though was OK.
Got used to using two monitors all the time at work - in my studio, two PC's (netbook = forum, desktop = music).
Think I must have pressed CTRL-ALT-DEL on the wrong keyboard!!

I'll get that e-mail off to Malc...

... on second thoughts, maybe I should get some sleep first, before I confuse my Mum with a bug report!!

If I put something inside the schematic, then exported exe works fine.

what you put in to work fine?

i have the same result also if there is something inside like you can see in exe export of my random keygen..

No, we misunderstood. Exe shows high CPU usage so or else. But this "CPU usage of an empty schematic" so to speak - does not takes the real CPU resources of the core that is processing streams (oscillators, filters, codes, asm, and so on) if I put something there. Otherwise it would be impossible to do anything due to CPU overload. So my idea is, that either this is very low priority load and/or (combined?) it affects second core (with higher streamy load I have c.a. 75-80% cpu usage here). As you know - SM/FS apps are single core, so I suspect this has to do with something interacting with the rest of the Windows. I don't know, maybe something with ruby, maybe GDI, maybne something else.

[trogluddite]

Same when there is Audio/MIDI parts too by the looks of it.
I tried with/without menu etc. and also "start audio on startup" turned off.

Think tester has the right idea - I have a few project that are meant for exe, and I never checked CPU because they always worked OK. So it looks like something that "gets out of the way" when FS is called on to do something.

Paraoxically - we've got serious issue - thus we've got a chance for serious update on-the-fly
