Borderlands 3 initially released only on the Epic Store. Later it was released on Steam and of course we wanted to see if Proton could handle it. We prefer a native port like all the other Borderlands, but until then lets play in Proton?
My daughter and I have played through all of the Borderlands games in co-op modes over LAN. They all ran almost flawlessly. In Borderlands 3 they have introduced the ShiFT account which still includes LAN play and online as always. We were not able to play over LAN so I had to purchase two copies of the game. We were able to play in Proton 5 and the game ran decent after the initial stutter of loading shader cache.
As we played there was one serious problem... a video is supposed to play during an early quest with Lilith. The video on the TV never plays and the quest is stuck. After reading several post with Windows and Linux gamers having the same problem, turns out Borderlands is using Media Foundation...
