Just dual boot at first, you don't have to wipe the windows partition. That way if/when you find a save file you need to copy over, you can go looking for it on your still existing Windows drive
Yeah I switched in 2020, but finally deleted my Windows partition a couple months ago. Never going back now.
And anymore, I feel like niche windows software is gonna be harder to run than almost all the games. The only games that don't work are the annoying anticheat ones.
I just got back from a vacation where Brotato filled that role.
