Hello @Rossco1337, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to https://github.com/ValveSoftware/Proton/issues/555#issuecomment-553884745.
Trying to launch this game with DXVK requires PROTON_FORCE_LARGE_ADDRESS_AWARE=1, otherwise the game will freeze, either in the opening CS, or loading a save. Playing the game with PROTON_FORCE_LARGE_ADDRESS_AWARE=1 is fine until you summon an Aeon in-game, where the animation never finishes and the game essentially "softlocks." Since the game uses DX10/11 using PROTON_USE_WINED3D leads to significant artifacting, and is essentially unplayable.

Symptoms
Steam Input is not working correctly in this game. Guide button/Big Picture can be navigated but none of my 3 controllers can interact with the game. Tested Switch Pro Controller, Dualshock 3 and Nyko Airflo (Generic Gamepad ID 124b:4d01),
Reproduction
I don't have a Windows environment or any friends who own this game to verify that this is a Proton issue, but I can't find anyone online using Windows with this issue. If this isn't a Proton issue, please direct me to the correct bug tracker. Thanks.
