The main difference is that with Steam Deck support, they can waste your time outdoors as well.
Except perhaps thats understating it.
On Low quality, theyre capable of hitting 60fps, but will often suddenly lurch down to 30fps.

It’s not clear what causes these drops, though I doubt its the Trilogys overall fidelity.
GTA III, the oldest and ugliest, actually sputtered below 30fps a few times.
