A few days ago, a mod appeared that unlocked the framerate in Metal Gear Solid Delta: Snake Eater. Now, additional tweaks have surfaced that let you enable features like Hardware Lumen Ray Tracing, Ray Reconstruction, and Frame Generation. These settings really should have been included in the in-game menu for an 80-euro release, but at least PC players now have a way to turn them on manually.

Hardware Lumen Ray Tracing

Activating Hardware Lumen brings better lighting, shadows, and ambient effects, though it does come at a performance cost. To turn it on, open the Engine.ini file located at:
AppData\Local\MGSDelta\Saved\Config\Windows

Inside the [SystemSettings] section, add the following lines:
r.Lumen.HardwareRayTracing=1
r.Lumen.Reflections.HardwareRayTracing=1
r.Lumen.ScreenProbeGather.HardwareRayTracing=1
r.LumenScene.DirectLighting.HardwareRayTracing=1

DLSS Frame Generation & Reflex

For NVIDIA users, DLSS Frame Generation can be enabled along with Reflex to cut down on latency. Add these commands:
r.Streamline.DLSSG.Enable=1
t.Streamline.Reflex.Enable=1
t.Streamline.Reflex.Mode=1
r.Streamline.DilateMotionVectors=1
r.NGX.DLSS.AutoExposure=1

FSR 3.1 Frame Generation for AMD

AMD users can enable Frame Generation too with just one line:
r.FidelityFX.FI.Enabled=1

Ray Reconstruction

If you want improved reflection quality on NVIDIA cards, you can also enable Ray Reconstruction by adding:
r.NGX.DLSS.denoisermode=1

Keep in mind that both Hardware Lumen and Ray Reconstruction will demand a strong GPU, so they’re best suited for high-end rigs.

Final Thoughts

These tweaks give PC players access to more advanced graphics features that aren’t officially available in the menus. They can make Metal Gear Solid Delta: Snake Eater look noticeably better, especially when paired with DLSS or FSR Frame Generation to offset the performance hit. Hopefully, the developers will integrate these options into a future update.
