This patch removes letterboxing (black bars) on Steam Deck native resolution without stretching.
Supported game version: 3.6.117.3735 (latest as of 1/6/2024) Steam/GOG, verified on SteamOS 3.5.19.
Installation:
- Download latest release
- Transfer d3d11.dll to
.../Divinity Original Sin 2/DefEd/bin - Launch the game, set resolution to 1280x800
Known issues: Short profile name may cause "(Y) Change Profile" text in the main menu to get a little bit off screen. Since GUI files are the only ones that cannot be easily overriden by mods, I decided to leave it be.
