Processing3 running really slow on RPI3

usernamevalid

Im not sure what I could expect performance wise from Processing3 so I just want to throw this out there.

I have a really simply app running on a RPI3 it displays a (750kb .png) at full screen(1920x1080) and occasionally draws some ellipses on top of it.

It runs at about 6 fps - is this normal , or am I doing something incorrectly?

Thanks

Are you loading the image inside draw()?

Could be any number of things, including a low powered device.

Hi Koogs

Thanks for the interest, i've attached the code below. (i'm not sure how to format it in the forum post).

//IMAGES
PImage img;

void setup() {
  fullScreen();
  img = loadImage("Background.png");  // .jpg image 750kb 1920x1280(size)
  img.resize(width, 0);

  // FONT
  font = createFont("Jaden.ttf", 55);
  smallFont = createFont("Jaden.ttf", 32); 
}

void draw() {
  image(img, 0, 0);   
}

that looks ok, but it doesn't do what your description said it does (no ellipses)

your filename says png, your comment says jpg... font and smallFont aren't defined (or used)

This is something on my radar... for some reasons, framerates really suffer when outputting to a high resolution monitor, whereas things are fine on lower resolutions.

@usernamevalid One thing you could try is to install the compton compositor, which might help, although I haven't tried so myself.

@koogs I dont have the code on me right now so this was the basic outline of what was happening. Ill post the exact code later this evening. Even so i get really slow frame rates just displaying the image at high resolutions. Do not experience this?

@gohai thanks ill look into this. So you experience the same thing? slow FPS when display full screen on rpi (1920x1080)

thanks

@usernamevalid Yes.
