The biggest steam deck compatibility issue is that the multiplayer mode wasn’t supported. From what I understand that hasn’t changed, but they moved it to a separate free DLC so it won’t affect the steam deck rating.
Other related improvements made are UI changes for steam deck, a deck graphics preset, updated FSR support, and other performance improvements.
Yeah so let’s rip that shit down before they suck the rest of the world dry. Fuck their profits. Their need for infinite growth is cancerous.
Stop giving corporations money. Especially the Nazi appeasing ones.
