Set OpenGL device for systems with integrated gpu

[DasPez]

Hi,
PixelFlow uses my integrated GPU as default. Is there a way to change this?

I would like to use a NVIDIA GTX960M

hey,

have a look in your nvidia control panel. I think you can modify the application profiles, e.g. for processing, to switch between integrated vs. dedicated graphics.

It looks like for Processing the profile is set (or no profile is set at all, and the default is just integrated), so that always the integrated graphics devices (intel HD graphics) is chosen. Which makes sketches that use shaders, or opengl in general, quite slow, especially compared to your gtx960m.

let me know if you figured out something.

maybe you find here something:
Nvidia Control Panel > Manage 3d settings > select preferred graphics processor

changing application profiles did not work ("javaw.exe" and "processing.exe") but "select preferred graphics processor" in the global settings fixed it!
Thank you
