You heard it folks, from the community manager of Ubisoft. Two weeks ago they said they're working hard on bringing good PC ports.EDIT: We can officially say that we're aiming for 60FPS on PC at launch. Our Beta build is still more performant at 30FPS, but you can expect to play at 60FPS on PC when the game is launched.
The final game will run in 1080p with 30 frames per second on Xbox One, PlayStation 4 and PC, and will support up to 5760*1080p on PC for triple screen set-ups. Right now the team is focusing on providing an optimal experience for all players. You can unlock it in the file you've found, but it may affect the game's performances. Your call
