ProtonDB says that my personal library in steam with over 800 games only has 1% games which don’t work, and a total of 7% that doesn’t just run when you click play. This means that the most pessimistic view of my library is that 93% of the games work, that’s probably more than on windows 11 for what I heard about compatibility for old games. I highly doubt your library is even remotely close to the 50% incompatibility you’re claiming.
They are. I do. If you need something in the level of complexity that “only” Microsoft office can provide, you shouldn’t be using excel to begin with, a simple script with a database will be a lot more powerful and fast.
GIMP not supporting CMYK natively is getting quite ridiculous. However as far as I remember there have been plugins for it since forever, plus this is only important for printed jobs, anything digital doesn’t need CMYK. Also depending on what you’re trying to do Krita might be a better option.
If that doesn’t matter then what does?
All of the ones I have tried work out of the box, also the ones that work is only so because windows has more users so companies bend over backwards to write drivers for it, but whenever companies give the same amount of treatment to both Windows and Linux the compatibility is always better on Linux, e.g. PlayStation controllers are a pain to get working on windows but work out of the box on Linux.
