Hi! This is my first post. I´m very exited to learn Processing to make visuals. I have a 2018 MacMini and a Razor CoreX with an Vega 64 as an eGpu. I tried the particles example and the performance is very low. Also i get this message in the console:

```auto
2019-12-30 16:45:45.025 java[15200:2903635] apply_selection_policy_once: 
prefer use of removable GPUs (via net.java.openjdk.cmd:GPUSelectionPolicy->preferRemovable)

```

I check the “prefer external GPU” for Processing but seems like i don´t really get benefits of the power of my eGPU.

Any advise for this type of configuration?

Could you confirm if you were using the P2D or P3D renderer? Something like: `size(400,600,P3D);`

Thanks for your answer @kfrajer . I´m using this code:  
[https://processing.org/examples/multipleparticlesystems.html](https://processing.org/examples/multipleparticlesystems.html)  
Btw I´m in MacOs Mojave  
If I add P2D or P3D to the size I get better results (more fluid particles) but the console returns this:

```auto

```

I will make more tests like check the fps to be sure if i can use my equipment the way i want.

Playing with the particles example. If I load 50 emitters the fps drops to around 35 and that value is exactly the same value with the eGPU and the internal GPU of the MacMini so, I can confirm that Processing is not using the eGPU. 😥

Anyone with an eGpu and OSX to test this?  
is there a way to check who is the renderer and the Gfx Card like in Resolume? (see picture)  
This is a breakpoint for me to use Processing. if I can´t use the eGpu i´m forced to see other options… 😢

try run  
[https://gitlab.com/snippets/1926924](https://gitlab.com/snippets/1926924) ,  
but set renderer to P2D or P3D

then some info regarding graphic is shown  
like here:

Finally! Seems like I´m using the eGpu! The Processing journey begin;)  
Thanxxx!

wrong syntax?

```auto
processing_journey.begin();

```

good luck for your project and have fun
