[D3D11] Titan Quest Anniversary Edition crashes when it is set to fullscreen

[Leopard1907]

Description:

Game crashes with DX11 backend ( default ) when game is set to fullscreen. Also does not start with fullscreen mode either. Default mode is set to borderless.

Window settings can be adjusted from steamapps/compatdata/475150/pfx/drive_c/users/steamuser/Documents/My Games/Titan Quest - Immortal Throne/Settings/options.txt with setting windowmode to 2 for Borderless , 1 for Windowed and 0 for Fullscreen.

Fullscreen mode works with wined3d and DXVK as well with using wine dxgi (WINEDLLOVERRIDES="dxgi=b")

I think this is the relevant part:

Can you post a full list of the display modes available on your system?

This function is known to be problematic on some systems (especially when using monitors that don't support 60 Hz for certain resolutions since some games hard-code that), but I cannot reproduce that here and I don't know why something like that would work on Windows.

Sure.

I don't know how to debug this or why it fails, can't reproduce on my end.

[doitsujin]

Does https://github.com/doitsujin/dxvk/tree/closest-matching-mode-fix fix this?

(Context: The game is asking for 1/60 Hz instead of 60 Hz, so we're looking for a 1080p 59Hz mode which doesn't exist)

[Leopard1907]

Thanks, dxgi from that branch fixed the issues.

Game can now start at fullscreen, also doesn't crash when switching to fullscreen from other windowing options.
