Metal Gear Solid Delta: Snake Eater recently debuted on PC, PlayStation 5, and Xbox Series S|X. Crafted by Virtuos, this Unreal Engine 5-powered remake of the classic MGS3 excludes certain modern PC features, though players have discovered workarounds.

While the game defaults to Software Lumen for lighting, enthusiasts uncovered methods to activate Ray Traced Lumen for enhanced visuals. MxBenchmarkPC’s YouTube tutorial outlines the process:

Navigate to AppDataLocalMGSDeltaSavedConfigWindows and edit Engine.ini. Append these lines:
[SystemSettings]
r.Lumen.HardwareRayTracing=1
r.Lumen.Reflections.HardwareRayTracing=1
r.Lumen.ScreenProbeGather.HardwareRayTracing=1
r.LumenScene.DirectLighting.HardwareRayTracing=1
r.Lumen.Reflections.MaxRoughnessToTrace=0.6
r.Lumen.Reflections.MaxRoughnessToTraceForFoliage=0.6

For sharper ray tracing effects, enable Ray Reconstruction via:

r.NGX.DLSS.denoisermode=1

To activate NVIDIA DLSS 4 Frame Generation, input:

r.Streamline.DLSSG.Enable=1
t.Streamline.Reflex.Enable=1
t.Streamline.Reflex.Mode=1

Surprisingly, these enhancements function without native menu options. Enabling Hardware RT Lumen causes a moderate performance dip (5-6 FPS on RTX 5080), though DLSS Frame Generation compensates by boosting frame rates to ~105 FPS at Performance settings. Future mods may unlock Multi Frame Generation for further gains. Note: A third-party tool is required to bypass the default 60 FPS cap.

Our PS5 critique highlights the remake’s strengths:

Metal Gear Solid Delta: Snake Eater masterfully revitalizes Big Boss’s origin story. Its careful modernization preserves the original’s quirks while elevating visuals and controls, offering the definitive version of this pivotal chapter in the series.
