MagicMirror stutters and doesn't run smoothly

[drx1984]

Hello everyone, can someone tell me why my Magic Mirror always stutters?
My system runs on an IntelNuc i5 32GB RAM 250SSD.
That should be enough to run stutter-free and smoothly??
I’ve already tried the MagicMirror on Windows and RasbianOS and it still stutters on both operating systems.
I have all the standard modules and additional modules like:

• https://github.com/Eunanibus/MMM-Globe
• https://github.com/darickc/MMM-BackgroundSlideshow
• https://github.com/shin10/MMM-FF-digital-rain
• https://github.com/AdamMoses-GitHub/MMM-ImageSlideshow
  decorated with five pages.

Can someone help me??

Thanks

@drx1984 is this on MagicMirror 2.26?

this is more than likely caused by the workload of the two modules globe and rain which make heavy use of drawing operations.

in 2.26 we turned off the electron gpu to eliminate errors for most users.
you can turn on the gpu by setting the environment variable

export ELECTRON_ENABLE_GPU=1

before launching MagicMirror with npm start

if you used my Linux install script and selected to use pm2, then the script is

~/MagicMirror/installers/mm.sh

a test to see if this will help is to launch a native browser (edge on windows, chromium on linux) and open the MM page
http://localhost:8080

you can also do that from a different system if you have enabled remote access in the MM config.js

@sdetweil
yes I installed the latest MagicMirror installation under Ubuntu with this automatic script:
bash -c “$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/raspberry.sh)”

where can you change the value of “ELECTRON_ENABLE_GPU=1”?
or under ~/MagicMirror/installers/mm.sh >change it like in the picture?

I have enough performance with my hardware.

Thanks for your help.

@drx1984 swap lines 4 and 5. and you forgot the ‘export’ keyword on line 5

in Linux, by default environment variable are not passed to children processes

and yes the script was mine.

[drx1984]

@sdetweil
aha ok, you mean like this:

?

[sdetweil]

@drx1984 yes…

then

pm2 status

to see what apps pm2 controls
then

pm2 restart xxx

where xxx is the number on the row, or the name on the row
examples

pm2 restart 0 

or

pm2 restart MagicMirror

[drx1984]

@sdetweil OK, thanks, I’ll test it.
Question: Is it possible to switch on exactly the same parameters for the GPU with MagicMirror in Windows?
export ELECTRON_ENABLE_GPU=1 ?

[sdetweil]

@drx1984 yes, you just don’t use the ‘export’ keyword on Windows

we don’t supply a .cmd file for Windows, and I don’t provide the install script or install pm2.

but its all the same functionally…

[drx1984]

@sdetweil aha ok then to line 4:
ELECTRON_ENABLE_GPU=1

[sdetweil]

@drx1984 if you are running under windows native… you don’t need to run in lsr
if you ARE running under lsr, then u need the ‘export’

just open cmd.exe and follow instructions in doc…
have to manually install nodejs on windows and git.

then a windows mm.cmd file

@echo off
cd %home%\MagicMirror
ELECTRON_ENABLE_GPU=1
npm start 

then execute

%home%\mm.cmd

[drx1984]

@sdetweil what do you mean by LSR? what does that mean?
I have now done this:
Of course, with “npm run server” it runs in the browser.
but how do I do it natively on the computer itself? When I enter the command “npm run start” there is an error in the cmd, something with the display.
I wonder if I did everything correctly, as you described it.

[sdetweil]

@drx1984 DISPLAY… you didn’t follow all the instructions …

see https://docs.magicmirror.builders/getting-started/installation.html#other-operating-systems

LSR (you can install the linux system runtime under windows too) …

[sdetweil]

@drx1984 said in MagicMirror stutters and doesn't run smoothly:

Of course, with “npm run server” it runs in the browser.
but how do I do it natively on the computer itself?

i don’t understand your question…

MM is a browser app.
it runs in Electron, (default), Chromium, Firefox, Edge, Safari, Midori, …

[drx1984]

@sdetweil oh yes sry, I saw it, ok now I have adapted the Package.jason and it is now running.

Did I do that correctly with the mm.cmd file so that the GPU is active? It still stutters or the clock module is also lagging behind :-(

Do you speak German too?

[sdetweil]

@drx1984 I don’t speak German, but can use translators to read/reply.

I mislead you, for Windows to set the env variable you have to use set

set ELECTRON_ENABLE_GPU=1

[drx1984]

@sdetweil So you mean?

…unbelievable does it require so much power? of the stottort anyway.

the IntelNuc is powerful enough, right?

[sdetweil]

@drx1984 yes, set ELECTRON_ENABLE_GPU=1

powerful enough? I do not know…
drawing lots of things on the screen takes lots of power. the screen is very slow compared to the processor…

I don’t run either of those module.

[drx1984]

@sdetweil yes certainly more than a Raspi 4 or 5.
then are the script and path correct?
I don’t notice any difference and it still stutters.

[sdetweil]

@drx1984 yes, looks OK.

I would try to run one module at a time

to disable the other, add

disabled: true,

after the module: line
so you don’t have to redo config.js

we don’t officially support Windows, so I don’t know if you have to do something else to enable gpu for electron.

you could try running under edge, at

http://localhost:8080

[drx1984]

@sdetweil yes, I have already tried the exact same configuration under Linux. > unfortunately it stutters there too.
That’s why I thought I’d try it on Windows level.
I will probably install Ubuntu on the Intelnuc again >because Windwos is not official, as you say.

But I don’t think it will stutter anymore, unfortunately.
