What GPU are you running?
Did you install the latest GPU driver?
Have you asked Adobe if it is a compatible GPU?
Really, Adobe could provide better answers I think. I can’t control which GPU Photoshop will work with. That is completely up to Adobe. Pixnub just tells Photoshop to do things. If you can’t do those functions with a keyboard and mouse in Photoshop then those functions won’t work with Pixnub either.
Anyway, curious to know what Adobe says about your GPU.
