I'm still working on adding some features (Specifically graphics settings and enhanced controller support), but I feel like that this release should be good enough for people just wanting the centered camera and ultrawide fixes.
The mod should automatically generate a config with the current screen resolution in the LWNFix.cfg file located in the "BepInEx/Config" directory. This is where you will need to adjust your screen resolution to the desired setting.
Additionally, the centered camera is disabled by default, but you can enable it by changing the "Centered Camera" setting from "false" to "true" inside of a text editor.
As always, extract this into the game's directory, and if you are playing the game through Proton (on the Steam Deck or Linux) add WINEDLLOVERRIDES="winhttp=n,b" %command% to the game's launch parameters in the game properties on Steam.
Tip: If you use the centered camera, adjust the in-game camera distance option to 3 or more.
