SM v2: enabled Mouse Move = high CPU use

I thing it just uses CPU; that is why there is a switch. IIRC not really a bug, but more of a non-optimized results.

Heres a fix I think. You need to limit the float outs from the Mouse Move.

Engage the Limiting button while looking at your taskmanager ( or whatever)

I did also compare the triggers that the mouse move outputs with a limited output and the difference is huge. As an example.

2 seconds moving the mouse around gave 50triggers when using a 25/sec limiter but 1700 triggers on the non limited output. Test the osm 🙂

Ohh. Another odd thing was that the Mouse Move also outputs coordinates when outside the real area. It seems it also outputs the valuse from the frame so you can get negative outputs if over Y 0 or left of X 0 and thats probably not a great idea? Use a limiter there too.

Thanks guys...

But as i mentioned in my post above it was O.K. before (= v1.17) and i have optimized all 2 the max - believe me!

I get old so i don't remember in which beta version we had this CPU jump before... the years with(in) SM flows like the wind...

Aliasant I will test ur OSM right now - of course!

Happy new Year Walter

Tested and as expected: i already use exo's trick!

After getting rid of the Mouse Over enabled it uses up to 3.85% (instead of 0 to 1.56%) with refreshing a 3.5 x 5 Grid with a real low tick7 😝

Weird. It doesnt use any cpu at all if I limit triggers. Unlimited I got about 5% cpu use. Can you up the osm were you get high cpu use?

sunsynth · 2 Jan 2011

No - it's my MiniTrak project... sorry!

I only refresh the red led area (and it's not the clock which eats up power - i only redraw a segment every second) Below my exe in a Zip (it's a symbiont for Traktor with auto Midi select etc. it uses only 88 MidiCC's 😉

aliasant · 2 Jan 2011

The only way I could get your minitrack to use any cpu was to move the Loop knob. If I turned it fairly fast it would go up to 9% from 0%

I have a similar problem with my multiband comp. It uses a lot of cpu just moving the mouse around in the exe without even clicking or interacting with the gui. Just moving the mouse around...... but I havent done any buigchase on it or any other modifications since SM2.0 came out,. i just opened it and saved a new .exe from 2.0

Havnt really been using SM2.0 that much. yet... Waiting for 2.01 😉

Thanks 4 testing ali...

Forgot 2 mention that it needs Midi to let the Leds flashing (MidiYoke and a .TSI 4 Traktor) also TTF's - but i get rid of them until release - i hope 😉

Hope malc is working hard on 2.01...

Cheers, Walter

P.S: I only redraw the Slider area 😮

Forgot to mention the midi thing too 🙂 I only got errors about missing midi devices or something. But still, check that loop-knob. Something is being recalculated or drawn way to often?

sunsynth · 3 Jan 2011

Yeah - overlooked that endless knob - will have a look - must be way 2 much calculations!

Cheers

Hi, this is my first post and i want to say hello and express my congratulations to all of you people of the forum,and also to Outsim´s Jorge and Malc.

Here are two examples of high CPU with graphics i want to show. It is a summing matrix i made using Oddson´s Keyboard and a modified ASM code from Matti.

Just 4 inputs and everything seems to be ok with CPU The i add the whole thing (for a total 24in 24 out matrix) and one core of my CPU jumps to almost 90 percent.

My setup is: cpu Intel core2 quad Q9550 @ 2.83 ghz Memory 4 GB (little bit less because OS) Motherboard Gigabyte EP45 ud3p Sound Card 2 RME Raydat PCI Express card (this is also another question i have, JUST 31 CHANNELS!? will be in another thread sorry) WinXP

Can anybody confirm High CPU usage just moving the mouse over the UI??

Cheers!

Hello and welcome, drhairs.

Yes, it happens because of the MouseOver primitives, that all need to calculate the position from the area, so the area also is calculated for every trigger/mouse-move. If possible, use an area sample n' hold to make the area calculation on load only and lighten up the cpu consumption.
