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.
