Hi, think again,
There are millions of people using Windows 7, they can switch to Windows 10 anytime for FREE, but they don't want to. Where will they go when Win7 is dead? I beliieve the only possible direction is Linux, since Apple is just another M$ - even worse.
I was hoping to use Substance Painter under Linux but the cancer (adobe) has just devoured it 5 days ago.
As you can see there is no industrial quality software for Linux now. GIMP is not an option.
@SrPx
GIMP is not good enough, no layer effects, no brush stroke along path, no slices, editing channels doesn't work properly, etc, etc... there is more, and I did give it a try for quite some time. For me the only true PS replacement is Affinity Photo. Vector software is not my business, if I wanted it I would probably go for Corel Draw or try Affinity D.
