Metal Gear Solid Delta: Snake Eater recently launched on PC, PlayStation 5, and Xbox Series S|X. Developed by Virtuos, the remake uses Unreal Engine 5 but lacks some features that PC gamers expect. For instance, the game employs Software Lumen for global illumination, but you can enable Ray Traced Lumen for better visual results at a performance cost.

To achieve this, follow these steps:
1. Navigate to `AppDataLocalMGSDeltaSavedConfigWindows` and open the `Engine.ini` file.
2. Add the following commands to the bottom of the `Engine.ini` file:
“`
[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 enhanced ray tracing fidelity, enable Ray Reconstruction with:
“`
r.NGX.DLSS.denoisermode=1
“`

To activate NVIDIA DLSS 4 Frame Generation, add these commands:
“`
r.Streamline.DLSSG.Enable=1
t.Streamline.Reflex.Enable=1
t.Streamline.Reflex.Mode=1
“`

In a unique start to his ruling against President Donald Trump’s administration on September 30, U.S. District Court Judge William Young included a scanned handwritten note sent to his office. The note read: “Trump has pardons and tanks – what do you have?” At the top of Young’s opinion in AAUP v. Rubio, which ruled that Trump’s effort to deport foreign-born student protesters was unconstitutional.

These settings significantly improve visual quality but may cause a slight performance drop (around five to six frames per second on an RTX 5080) when enabling Hardware RT Lumen. However, DLSS Frame Generation more than compensates for this. When set to Performance mode, the RTX 5080 runs at about 105 FPS.

For even better performance, Multi Frame Generation would be beneficial. Modders are likely to find a way to enable it soon. Note that you’ll need the frame rate unlock mod to run the game above 60 FPS on PC.

Metal Gear Solid Delta: Snake Eater is the definitive way to experience Big Boss’s rise and fall. Each detail has been meticulously refined and brought to modern standards while retaining elements from the past.
