A screenshot of the detailed Graphics & Display options menu from the game 'Mouse P.I. For Hire' (2026), running on a Nintendo Switch 2. The menu maintains the game's strict black-and-white noir visual style. The left side lists Display settings: 'FOV (Field of View)' and 'Gamma Correction', showing adjustable sliders. Below these, toggles and sliders are available for 'Brightness' and 'Contrast'. The right side shows the Graphics settings, featuring the 'Graphics Preset' dropdown menu, currently set to 'Performance Mode (60 FPS)' with action arrows emphasizing fluidity. Below the preset, detailed advanced graphics options are visible but greyed out, with a small caption note: 'INDIVIDUAL OPTIONS LOCKED UNDER CURRENT PRESET.' A classic 1930s 'rubber hose' cartoon mouse character, Jack Pepper, in a trench coat and fedora, stands to the side of the menu, gesturing with a smile towards the performance setting. The background is a textured, gritty noir city street under twilight, consistent with the overall game aesthetic. The Switch 2 UI elements (ABXY buttons) are visible at the bottom of the screen.
