_How could I force the program to use the GPU instead of the iGPU?_

\_  
Hello.

Been developing a program on my desktop, where it runs fine. The issues show when I try to run it on my old laptop.

Program uses shaders, relying heavily on the GPU, and when it gets a bit more demanding it crashes.

Using the task manager I noticed the crashes happen right after a spike in GPU usage. Also noticed that the program is using the weaker iGPU [Intel(R) HD Graphics 360] instead of the GPU [NVIDIA GeForce GTX 1060 with Max-Q Design].

Edit: Running Windows 10 and already tried updating drivers.

The error thrown is:

Managed to fix the issue!

Solution is [changing program’s default GPU](https://pureinfotech.com/set-gpu-app-windows-10/).  
Chosen program was **java.exe** at _processing\processing-4.2-windows-x64\processing-4.2\java\bin\java.exe_
