The primary goal for Blight: Survival optimization is Combat Responsiveness and Clarity. The game’s default “Cinematic” look uses heavy motion blur, film grain, and high-intensity Lumen reflections that can make it difficult to read enemy telegraphs in dark forests. By tweaking the scalability groups, we can maintain the “gritty” atmosphere while stripping away the visual clutter that leads to input lag.
Hardware Compatibility & Expectations
- UE5 Requirements: This game is a true “Next-Gen” title. Even on “Minimum” settings, a GPU with 8GB VRAM and hardware ray tracing support (RTX 20-series or RX 6000-series) is highly recommended.
- CPU Simulation: The Blight AI and physics-based armor interactions are CPU-heavy. Lowering “Effects Quality” is the best way to gain FPS on older processors.
- Upscaling Necessity: Because the game uses Nanite, running at Native 4K is nearly impossible for mid-range cards. DLSS/FSR/XeSS are essential components of this config.
File Location
The configuration files are located in your local AppData directory: %LOCALAPPDATA%\BlightSurvival\Saved\Config\WindowsNoEditor\ (Note: If the folder is named differently due to developer updates, look for the “BPSR” or “Haenir” folders in Local AppData.)
Best GameUserSettings.ini for Medieval Realism
Update the [ScalabilityGroups] section to these values for a high-performance/high-fidelity balance:
[ScalabilityGroups]
sg.ResolutionQuality=100.000000
sg.ViewDistanceQuality=2 ; Medium (Keeps distant enemies visible without excess clutter)
sg.AntiAliasingQuality=2 ; Balanced (Necessary for UE5's stability)
sg.ShadowQuality=1 ; Low/Medium (Shadows are heavy in the dense woods)
sg.PostProcessQuality=1 ; Low (Disables heavy bloom and lens flares)
sg.TextureQuality=3 ; High (Keeps your armor looking sharp)
sg.EffectsQuality=1 ; Low (Reduces CPU load during gore/blood effects)
sg.FoliageQuality=1 ; Low (Crucial for visibility in the Marshlands)
sg.ShadingQuality=1
sg.GlobalIlluminationQuality=1 ; Sets Lumen to a high-performance mode
sg.ReflectionQuality=1Engine.ini Tweaks for Visual Clarity
Add these lines to the bottom of your Engine.ini to remove the “Vaseline” smear and improve the medieval aesthetic:
[SystemSettings]
r.Tonemapper.GrainQuantization=0 ; Removes Film Grain
r.Tonemapper.Quality=0
r.SceneColorFringeQuality=0 ; Removes Chromatic Aberration (Blurry edges)
r.MotionBlurQuality=0 ; Disables Motion Blur for better parrying
r.DepthOfFieldQuality=0 ; Keeps the background sharp
r.Lumen.Reflections.Allow=0 ; Disables Lumen Reflections for massive FPS boost
r.MaxAnisotropy=16 ; Keeps ground textures sharp at an anglePro Tip: In a medieval combat game where timing is everything, r.MotionBlurQuality=0 is your most important setting. It prevents the screen from “smearing” when you turn your camera to track a flanking zombie, allowing you to stay oriented during chaotic scrambles.
Key Parameters Explained
| Parameter | Recommended Value | Impact |
| sg.GlobalIlluminationQuality | 1 | Controls Lumen. Setting this to 1 provides the best FPS-to-visual ratio. |
| sg.FoliageQuality | 1 | Reduces the density of tall grass in the Marshlands, making “Blighted” easier to spot. |
| r.SceneColorFringeQuality | 0 | Fixes the “color bleeding” on the edges of your knight’s armor and weapons. |
| sg.TextureQuality | 3 (High) | Keeps armor textures detailed. High textures usually don’t hurt FPS if you have 8GB+ VRAM. |
In-Game Optimization Strategy
To complement your config tweaks, adjust these in the Options > Video menu:
- Super Resolution (DLSS/FSR): Set to Quality. If you are still below 60 FPS, use Balanced. Avoid “Ultra Performance” as it ruins the detail of the chainmail.
- NVIDIA Reflex / AMD Anti-Lag: Set to On + Boost. This reduces the “render queue” lag, which is vital for the game’s directional blocking system.
- Gamma/Brightness: Set slightly higher than default. Blight’s “dark” areas are pitch black by design, and a small gamma boost helps you spot enemies hiding in corners.
Troubleshooting & Common Fixes
- Stuttering in New Areas: This is common in UE5 games due to shader compilation. After applying these tweaks, the first 10 minutes might have small hitches while the game re-caches.
- Game Looks Too “Clean”: If you prefer the cinematic look, re-enable
r.Tonemapper.GrainQuantization=1in the Engine.ini. - Settings Resetting: If your FPS lock or resolution keeps reverting, right-click GameUserSettings.ini > Properties > Check Read-only.
Frequently Asked Questions (FAQ)
Does disabling Lumen Reflections (r.Lumen.Reflections.Allow=0) ruin the game?
No. The game will fall back to Screen Space Reflections (SSR). Your armor will still look metallic and shiny, but you will gain roughly 10–15% more FPS because the engine isn’t ray-tracing every puddle in the swamp.
Why is Foliage Quality so important in Blight?
The game uses extremely dense foliage to hide enemies. While immersive, at High/Ultra settings, it can be a “visual wall.” Setting it to Medium/Low removes the smallest tufts of grass while keeping the main trees and bushes intact.
Is “Nanite” affected by these settings?
Nanite is an engine-level geometry system that doesn’t have a simple “On/Off” switch in the user config. However, lowering sg.ViewDistanceQuality reduces the number of Nanite clusters the engine has to manage at once.
Conclusion and Expected Results
By manually refining your GameUserSettings.ini and Engine.ini, you are optimizing Blight: Survival for competitive survival. You can expect the removal of distracting post-process filters, a significant reduction in input lag during melee combat, and a much clearer view of the undead through the fog and mud of the 14th century.
