I use the default config with the sensitivity turned up to 225% (which makes the touchpad’s left-right width equate to a bit more than the full screen width); that works fine for me. I play a lot of deckbuilders, point-and-click style games, isometric RPGs, tactics games, or just generally older / indie titles that don’t have good native controller support, and it’s been a lifesaver for those.
It doesn’t feel as good as a mouse, I won’t claim that it does, but it makes those games go from “unplayable” to “playable” and that’s the jump I was looking for.
Casual players can be fine with some games. Some actually become easier with Archipelago (e.g. Noita, Risk of Rain 2) since you’re getting meta-progression between runs that normally wouldn’t be there. Others though are especially punishing for new players (Doom comes to mind - you have to be pretty intimately familiar with the levels. There’s keys hidden in secret areas sometimes, for example, and ammo can be very scarce.)
