As someone with a lower end spec desktop, I personally think that running emulated games or just normal PC titles at a much lower speed isn’t an issue. Especially since I don’t play FPS games.
I’m one of those people who’d be fine running a game at fluctuating 30FPS just so long as I can play it. It’s how my desktop handled mc before I boycotted it for minetest and how it handles minetest when I’m not on a super flat void world due to mod strain.
