This was on a fresh DNG, not some big existing project.
Perhaps with massive amount of spend it can be brought up to parity to work even for complex Photoshop projects.
It's not as bad as a few days ago, however it's extremely slow and lots of little bugs to the point I would never use it professionally. Weird things too, like my entire mouse pointer is slow, drawing with a brush is slow and jaggy, editing a vector and the points don't highlight properly or ending the edit and suddenly it randomly moved somewhere on the screen. Just very clunky, bad feeling and not really usable compared to photoshop.
I'll keep an eye on it out of curiosity, but right now it's unusable in a professional context.
