Windowed borderless is unchanged and works with or without Archthrones. Exclusive fullscreen is not modified.
The ini cap now defaults to 120. The sprint fix follows the game's frame time, so that cap does not bring back the old wall slowdown. Set FixSprintSlowdown = 0 to restore it.
Linux and Steam Deck still need:
WINEDLLOVERRIDES="D3DCompiler_43.dll=n" %command%
Install D3DCompiler_43.dll and FPSconfig.ini next to DarkSoulsIII.exe. If you already have an ini, set fps to whatever you want and keep FixSprintSlowdown = 1. Use the game's windowed mode for borderless.
