Metal Gear Solid Delta: Snake Eater Enable Ray Tracing Mod v1.0

                    
The Enable Ray Tracing Metal Gear Solid Delta: Snake Eater Mod switches on hardware Lumen for reflections, direct lighting, and indirect lighting via a clean Engine.ini tweak that the base menu doesn’t expose.
It’s a big win for visual purists and screenshot hunters: foliage, wet materials, and character shading pick up more believable bounce light and specular behavior, as long as the PC has modern RT hardware.
Mod features

Hardware Lumen RT enabled: Activates ray tracing for reflections, direct lighting, and indirect lighting to replace the default software Lumen path.
Higher-fidelity lighting and materials: Improves world and foliage shading, adds richer GI, and delivers cleaner specular on metals and water.
Config-only approach: Works by appending SystemSettings lines to Engine.ini, avoiding heavy hooks and staying easy to revert.
Performance-friendly workflow: Pairs well with a fixed FPS target, an upscaler, or frame generation if the goal is to claw back performance lost to RT.

Installation & Prerequisites

Back up: close the game and back up your existing Engine.ini so you can revert quickly if needed.
Download: get the Enable Ray Tracing mod from the Downloads section.
Extract & place: copy the provided Engine.ini into %LOCALAPPDATA%\MGSDelta\Saved\Config\Windows (for example: C:\Users\YourName\AppData\Local\MGSDelta\Saved\Config\Windows) and overwrite when prompted.
Make it read-only: right‑click Engine.ini, open Properties, and check Read‑only to prevent the game from reverting the new settings on launch.
Verify lines (advanced): if editing manually, ensure these keys exist under [SystemSettings]:r.Lumen.HardwareRayTracing=1
r.Lumen.Reflections.HardwareRayTracing=1
r.Lumen.ScreenProbeGather.HardwareRayTracing=1
r.LumenScene.DirectLighting.HardwareRayTracing=1
Launch & check: start the game and test a high‑contrast scene; expect a performance cost versus software Lumen. Consider enabling an upscaler or frame generation to stabilize frametimes.

FAQ & tips

Do I need RT hardware? Yes—hardware Lumen requires a DXR‑capable GPU and current drivers. Software Lumen remains the fallback if RT isn’t available.
The game overwrote my config: re‑apply Engine.ini, confirm Read‑only is enabled, and make sure the section is named exactly [SystemSettings].
Performance dips at night/rain: validate frametimes in a demanding scene, then add an upscaler or frame generation to recover smoothness.
