There is a Photoshop CC installer for Linux hosted on Github. I’ve tried it - it works. It’s just not a great experience. Saving files is a pain, because the export option does not exist. You need to use Save As, and that only works with a hacky workaround.
The UI doesn’t update until you do something that forces it to re-draw (like zooming or panning), which is a real pain when transforming or moving layers - for example. Plus, the UI doesn’t scale. You need to use Photoshop in complete fullscreen otherwise parts of the UI will be missing.
AI filters do not exist, for obvious reasons. However, most other filters work fine.
And most obviously, performance has an extreme degradation. It’s really slow.
But yeah, would probably get a “Bronze” rating on WineHQ, which is better than not working at all - I suppose. It’s progress?
