I have been attempting to get the game to play on my ultrawide properly but have failed to get it to work. The long story short is that, regardless of whether I am using wayland, x11 or pure steam mode, the game only allows up to 2560x1080 as a resolution, and while normally I really don't mind having black bars on the sides of this monitor when playing games that don't support the full res, my mouse input is not synced up to the game at all, changing any settings requires me to move the mouse well off to the side and to essentially guess where it is being detected by watching for menu items to highlight. As such this makes the game unplayable on this monitor.
Below are some technical details from my attempts as well as my set up:
System:
OS: NixOS (Linux 6.12)
Monitor: ROG Strix XG49V (3840x1080 @ 144Hz native)
GPU: NVIDIA GeForce RTX 3060 Ti (Driver 580.476.128)
Rising World Version: 0.9.1
Issue:
The game only detects resolutions up to 2560x1080, despite the monitor's native resolution being 3840x1080. This occurs regardless of display server (tested on Wayland/Hyprland, X11/i3, and gamescope).
Technical Details:
xrandr correctly reports 3840x1080 as available and active
Unity detects the monitor: Display 0 'DP-3 49"': 3840x1080 (primary device)
But SDL enumerates only 25 resolutions, maxing at 2560x1080
Player.log shows: requesting fullscreen 3840 x 1080 at 0/1 Hz followed by fallback to Set resolution to 2560x1080
Expected:
3840x1080 should be available in the resolution dropdown.
Workaround Attempted:
Manually editing prefs file to force 3840x1080 causes the game to request it, but the request fails and falls back to 2560x1080.
Note:
Other games (Cyberpunk 2077, Terraria) correctly detect and run at 3840x1080 without issue.
