I think only the folder is still named Ubuntu12 or something (like Dota 2's folder is still called Dota 2 Beta), libraries in it surely are more recent than that. And even then, native Linux ports of games don't run that well anyway. Especially older ones, like Tomb Raider 2013, Deus Ex Mankind Divided, Alien: Isolaton, those all will run much better over Wine. I kind of expect newer ports to fall apart as well in the future. I was playing Hollow Knight the other day (native port) and it drops FPS quite often on my laptop (hybrid amd+nvidia), while through Wine those drops don't exist almost at all.
