If the game closes immediately after launching, your graphics card or monitor may not support the custom resolution, or the executable version is incompatible with the patcher.
While the 3D racing world scales beautifully to ultra-wide resolutions, the 2D UI elements (speedometers, menus, HUD) may stretch horizontally.
