.. and what else will be included in the update? :lol:

A bunch of surprises.

- self-evolving engine with optimization protocols based on fuzzy logic, natural atractors, chaos theory, and so on,
- system/hardware auto-rebuilder to help you adjust your machine to the version of FS you use (from 8 up to 256 bits, and with quantum architecture support - but be careful - singularities on the go),
- the greatest marketing service, so that you don't need to play around your business, and can stay focused on creativity (it will even make it's own apps and sell it, to earn money for you),
- but - wait - you don't need to be creative - just point through the new BCI application that you would like to play with something new, and FS will create something according to your taste, following your brain patterns,
...and much more!

:-)

OR

- minor update: CPU usage during idle - fixed.

Damn - had this prob with my own Image Viewer ;-)

project...
so even no blue parts in it

... in v3.0.2 it works fine again

Hope malc can fix this soon

...bump - after one month; any news malc?

...my update support ends in less than one month

My too, but I was told that an update fixing this - should be available this month. The CPU issue was introduced in version 3.03 (which is a real madness for laptop users with no fan control), and lot of projects from 3.03 don't load anymore in 3.02 (where was no such problem). So I guess this update should deal with rather basic things. But who knows? Maybe it will introduce something new and interesting too?

I am strugling with the same problem..
A empti scematic with the ASIO output module. Nothing else. The CPU load hits 50% !!

i am pritty sure that i never had the problem on SM..

Also. How can FS be single core ? I always got cpu load on both my cores when running a FS .exe program ?

The problem was introduced with the last update, so it's only been around a short while - as Malc knows exactly what code he changed last time, he's confident that it's an easy fix.
The CPU usage is also a very low priority thread that just polling things when stuff is "idle", so the CPU power will be given up as soon as another, more important, process asks for it - so it won't affect other applications much, it just drains your laptop battery and makes the fan run all the time!!

Well, it's truer to say that SM/FS doesn't take any control over which cores it uses. All audio runs in one CPU thread, all MIDI in another, then also Ruby and the "green" stuff. Drawing things on screen is also handled by making calls to the GDI+ part of Windows, yet another thread.
As FS doesn't specify any special threading behaviour, the PC is free to run each thread on whichever core it likes - so the CPU load may be spread out a little bit because, for example, your GUI is drawn by a different core than is running the audio streams.
As the biggest CPU user for plugins is usually the audio streams, and that's all on one thread, people tend to say that FS uses "only one CPU core" - as one whole core sets the limit for how much audio DSP you can do.

Well.. With the current error reprotet, it really dosent matter!! If a empty scematic takes 50% cpu load on two cores (also two on a 4 core system!) it makes no sence to talk about cpu loads at all!!

Hope you soon will fix this problem.. It is a MAJOR problem since it is impossible to know how and where to code optimaze for slower systems!!
