Anyway, Pixnub SPA won’t run Face Detection at all until you can get the graphics card fixed so Photoshop can turn it on in the preferences. You can run SPA with player mode 4 because that is edge detection only. You can also use modes 7,8,9 or 10. Modes 1,2,3,5,6 are the face detection modes that won’t work without GPU.
If it becomes too costly to fix the PC then I recommend a M1 Mac mini. The cheap $699 baseline Mac Mini M1 will run way better and faster than a $4000 gaming PC with and Expensive NVIDIA RTX GPU. It’s not even close either. Mac M1 destoys any PC for processing speed in Photoshop and with Pixnub. Just an idea is all 🙂
