Can we get a Steam Deck perfomance fix?

[Rinaldus]

EDIT: THERE'S A FIX. From another thread, use the following launch cmmand:
MESA_LOADER_DRIVER_OVERRIDE=zink %command%

With Time Stranger announced and people bound to come back and check out the first Digimon Story game, can we please get a Steam Deck perfomance fix? Game runs full 60fps no problem in desktop mode, but Kowloon struggles to stay in the mid 30s on game mode. So silly. Not sure if it's a vsync issue or what, but would really appreciate a fix from the devs or Valve please.
