If you want to use GLSL and a pressure library, use P2D.

If not, use FX2D, because:

- Rounded Rectangles in `rect(100,100,200,200,25);` look incredibly weird, if you want clear strokes. (compare it using FX2D / Default renderer & OPENGL, it looks different)  
 ![image](https://canada1.discourse-cdn.com/flex036/uploads/processingfoundation1/original/3X/1/8/1842b8d622cf1b7c23bd57fed6563cd2b348d48e.png)

- Key Presses in OPENGL behave completly different then in the default renderer or FX2D (hard to describe, try example), example:

```auto
import processing.javafx.*;

String inputString = "";

void setup() {
  size(400, 200, FX2D); //try P2D or FX2D
}

void draw() {
  background(220);
  fill(0);
  textSize(24);
  text(inputString, 20, 40);
}

void keyTyped() {
  inputString = inputString + key;
}

```

- Cursors are the OPENGL default ones, and when used multiple times in one draw call, they start to glitch.

```auto
void setup() {
  size(400, 400, P2D);
}

void draw() {
  background(220);
  cursor(ARROW);
  cursor(ARROW);
  cursor(ARROW);
  noCursor();
}

```

Why not use the default renderer? Because FX2D gives a performance increase like P2D, but doesn’t behave like OPENGL.

This is making it hard to develop something cool, due to these features being needed to develop a good functioning application.

I wish the processing devs (if its processings fault for these errors) would change some of the OPENGL functionalities. They probably can’t do anything about some of the stuff.

I don’t wanna bash OPENGL, but it annoys me, and i had to let it out.

These “perks” have been tested on Windows & Linux.

Happy coding 🙂

Sounds good. How do I install javafx in processing 4.3?  
Cheers,  
Adrian.
