Tip for macOS users

When running a program, the console will display Warning: Running on macOS without -XstartOnFirstThread JVM argument. To clear this warning (and enable debugging):

• Open the Run > Edit Configurations... menu.
• Add -XstartOnFirstThread in the VM Options text field.
• Click Ok to close the dialog.

Tip for Windows multi-GPU users

If your computer has multiple GPUs, you can choose which one OPENRNDR uses like this:

• Run the openrndr-template program by clicking on the green triangle. In IntelliJ, look at the console in the bottom area and note down the full path of the java.exe program being used. It probably starts with something like C:\Users\....
• Open the Windows Graphics Settings.
• Click Browse and find the exact same java.exe you noted down earlier.
• Click Options and choose your preferred GPU, then click Save.
