The Outer Worlds 2 Definitive Engine Tweaks Mod v1.0

                    
Want to eliminate shader stutter, traversal hitching, and distracting micro-flicker in The Outer Worlds 2 without sacrificing graphics quality? The Definitive Engine Tweaks Mod uses carefully chosen Unreal Engine 5 config flags to optimize performance, front-load shader compilation, and enable robust pipeline caching. It is lossless—meaning your visual fidelity stays entirely up to your in-game settings, and you won’t encounter surprise downgrades or risky mod hacks.
This lightweight tweak works across all major graphics cards (NVIDIA, AMD, Intel) and CPUs. It improves smoothness during high-action scenes, loads assets more predictably, and saves time by handling shaders before you hit new areas. Optional settings can further optimize upscalers (DLSS, FSR, XeSS) and tailor shadow/RT quality, but you can skip them if you prefer to keep your own in-game choices.
Caractéristiques

Lossless optimization: No graphics downgrades. You keep all image fidelity, adjusting only what you want in game menus.
Universal & safe: Compatible with nearly any hardware—no vendor hacks, DLL injection, or risky changes.
Stutter and hitch reduction: Compiles shaders during loading screens, caches pipelines across sessions, and keeps Lumen/Nanite on optimal, stable defaults.
Cosmetic improvements: Disables film grain, vignette, and chromatic aberration for clean, sharp visuals (you can re-enable these if you prefer).
Optional GameUserSettings: A ready-made profile for quick performance tweaks—DLSS Quality + Frame Generation ON by default for RTX users, FSR3/XeSS Balanced for AMD/Intel. Hardware RT off for best CPU/stutter performance.

Tips & Recommendations

If you use RTX, select DLSS Quality + Frame Generation ON. For AMD/Intel, swap upscalers in menu or .ini file.
Keep Hardware Ray Tracing off for now (added stutter, little gain).
Shadows set at Medium for good performance without excessive upscaler noise—tune all other graphics as you prefer.
Compatible with UI, texture, photo/visual mods, ReShade, and display enhancements.
Expect minor stutter on first use as new shaders cache; should smooth out quickly on repeat runs.

How To Install

Back up your current Engine.ini and, optionally, GameUserSettings.ini.
Drop the provided Engine.ini file into %LOCALAPPDATA%\Arkansas\Saved\Config\Windows.
Optionally, replace or edit GameUserSettings.ini from this mod for instant upscaler and shadow tweaks.
Launch the game and play at least 5–10 minutes to let UE5 build/refresh shader caches and apply all performance changes.
If the launcher or a patch rewrites configs, simply re-apply this mod’s files. To uninstall, delete these files or restore your original settings.
