Hello, I might have figured out part of their issue. Assuming they're relying on an AMD graphic card, it seems that Formamorph tries, by default, to run a local A.I. model on the GPU... but will only accept Nvidia models.
How do I know? I've looked into the Settings and saw that Formamorph 2.3.0 looks for a Nvidia graphic card and refuses to acknowledge my AMD Radeon 7900 XT. Which is sad, because it has so much VRAM available to use.
