Ah it seems you have me confused, I'm not the guy who needs Photoshop.
Interestingly, I have been dual booting Linux and windows for a while in the past. That was way, way back though, around 2010 I'd say. Back then, gaming on Linux was still very much hit and miss (but mostly miss, for me) and I had nothing better to do than gaming after uni so I did not have much of a choice.
I'll say, maybe it was dumb luck, more likely it's Windows getting shitter, but dual booting used to be much less of a faff from what I can gather. For instance I never had a windows update torch my boot record to force itself instead of grubby grub. I understand that can be a common occurrence these days.
After that and getting a real job TM, I had much less time for it so I wiped that sad excuse for an OS from my system with a grin and never looked back. Which also means, there's been a decent chunk of time I only did with whatever was available in Linux as I could not be bothered with wine. So I don't know how easy things have become, my only exposure is now the odd bit of gaming again but, as you know, Steam just makes it work for me.
+1 for Krita, I don't need much but it more than fits the bill for me. There are other threads in there though that do mention some stuff is just a lot harder when compared to PS for peeps who are actually good at the stuff.
LLMs (ok ok,not local) now come by default on Windows, without keyboard or mouse, just the mandatory connection to the mothership. So, yay windows?
maybe I should try Kenshi sometime...
