XESS/FSR=Quality, Everything to low, effects to medium. Use mod „Ascendio” version dedicated to Steam Deck. Alternative use mod to replace DLSS with FSR 3.1.

Low settings, FSR=Quality, TDP Limit to 11W, Gamescope FPS limit to 30. In order to obtain even and smooth frames, I recommend using "Power Tools" with Decky Loader and setting the CPU clock limit to 2400Mhz

First steps to buttery smooth 30 FPS - Gamescope to 30 FPS - TDP Limit to 12W - GPU Clock to 1300 MHz DISPLAY * Window Mode: Exclusive Fullscreen * Display Resolution: 1280x800 * VSync: Off * Refresh rate: 90hz * Framerate Cap: 90 * Upscale Method: AMD FSR 3.1 * Upscale Quality: Quality GRAPHICS * Level of Detail: Low * Texture Quality: Medium * Texture Filtering: 2x Anisotropic * Shadow Quality: Low * Screen Space Shadows: Off * Image Based Lighting: On * Bounced Lighting: Off * Ambient Occlusion: Performance * Screen Space Reflections: Off * Real-Time Reflections: Off * Cloud Shadow Reflections: Off * Sub-surface Scattering: Off * Refraction Quality: Medium * Depth of Field: On, Low * Motion Blur Quality: Medium * Particle Density: Low * Volumetric Effects: Low * Lens Flare: Half Resolution
