After editing Engine.ini and GameUserSettings.ini, you MUST set the files to Read-Only.

If you skip this step, the game will overwrite your settings the next time it launches.

How to do it:

Right-click Engine.ini

Select Properties

Check Read-only

Click Apply

Repeat the same for GameUserSettings.ini

✔ Your tweaks are now locked and cannot be reset by the game.


🧪 Recommended Hardware

These settings are ideal for:

RTX 4070 / 4070 Ti / 4070 Ti SUPER
RTX 4080 / 4090
RX 7900 XT / XTX

If performance is too low, reduce:

r.ScreenPercentage=150

Try 140, 130, or 120.

You can expect:

✔ Ultra-sharp visuals
✔ Huge shadow resolution improvement
✔ Better SSR reflections
✔ High-quality fog and materials
✔ Zero texture pop-in
✔ A “next-gen” look without mods

My main monitor is 2K, but by increasing the internal resolution to 150% using r.ScreenPercentage=150, it becomes equivalent to 4K

🔎 Quick note about sg.ResolutionQuality vs r.ScreenPercentage

sg.ResolutionQuality is the menu/scalability entry; it often remains at 100 because r.ScreenPercentage in Engine.ini overrides actual render scale. If you set r.ScreenPercentage=150 in Engine.ini, the engine will render at 150% regardless of sg.ResolutionQuality value.

You may notice several ray tracing parameters inside the configuration files (such as r.RayTracing.Reflections=True, RayTracingShadows=True, etc.).
These settings appear because Lies of P was developed on Unreal Engine 4.27, which includes built-in ray tracing keywords at the engine level.

However:

Lies of P does NOT include any ray tracing shaders or pipelines in its final build.

The developers completely disabled DXR support during compilation. This means the game contains:

No ray tracing shaders

No DXR acceleration structures

No ray tracing passes

No hardware RT pipeline

No RT fallback shaders

Because the ray tracing pipeline is not compiled into the executable, enabling .ini values cannot activate ray tracing.

❗ About “Ray Tracing Mods” — They Are All Fake

You may find mods or YouTube videos claiming to “unlock ray tracing” in Lies of P.
These are 100% fake.

Why?

Because you cannot enable ray tracing in a game that does not contain the RT pipeline.
Unreal Engine requires specific DXR shaders and rendering passes to be compiled into the final build, and Lies of P has none of them.

Therefore:

✔ The .ini ray tracing values exist
✘ But they do nothing
✘ And any “RT mod” is impossible
✘ Because the game lacks the required DXR pipeline entirely

❗ About “Ray Tracing Mods”

Those so-called ray tracing mods don’t enable real RT — the engine has no DXR pipelines. They only tweak SSR, shadows, fog, and post-processing values. All of these improvements are already applied (and in higher quality) by the parameters included in this guide, so the mods don’t provide anything beyond what you get here.

⚠️ Important: You cannot add Ray Tracing to a Game that doesn’t support It, no Mod can do It.
⚠️ The fake “RTGI / RTX” Mods from PascalGlitcher, Massiancer and others: All their paid Patreon mods are a scam! Now I’m going to explain the real reason why these mods use misleading names

There is too much ignorance, people like to confuse SSR (screen space reflection) for ray tracing, two totally different things.

If a game does not have native Ray Tracing, there is absolutely no way to add real Ray Tracing through mods.
No injector, no preset, no ReShade filter, no tweak, and no “RTGI mod” can create Ray Tracing in a game whose engine was never built for it!

This is a hard technical limitation, not a matter of skill or modding ability.

Mods created by the scammers like PascalGlitcher, Massiancer, and other Patreon authors are often advertised as RTGI, RTX upgrades, Ray Tracing mods, or tools that “enable Ray Tracing” in games that don’t support it.

All these mods claim to deliver something that is technically impossible.

🔍 Why Real Ray Tracing cannot be added through mods?

True Ray Tracing requires deep engine integration, such as:
DXR or Vulkan RT pipeline
Ray Tracing–compatible shaders
Materials authored for RT
BVH (Bounding Volume Hierarchy) acceleration structures

a renderer built specifically to support ray tracing passes

If any of these elements are missing, and they are missing in games without RT, no mod can create them.

There is no hidden setting, no unused shader, no “locked feature” waiting to be enabled.

🔍 What These Patreon “RTGI” mods Actually Do

Despite the RT marketing, these mods:

❌ do NOT trace rays
❌ do NOT add global illumination
❌ do NOT interact with geometry
❌ do NOT alter the game’s rendering pipeline

They are just ReShade presets using screen-space effects:

SSGI (fake GI)
SSAO
fake reflections
color grading
sharpening
bloom overlays

They only modify the final 2D image, NOT the actual lighting.

🔍 Why are these mods Scams?

The main issue is the false labeling.
Selling a ReShade preset as if it were real Ray Tracing is misleading, especially when users are told:

it “enables RTGI,”
it “simulates RTX lighting,”
it “activates hidden RT features,”
or it “brings Ray Tracing to any game.”

None of this is true.

You are paying monthly for something that cannot deliver what it promises.

🔍 Why These Mods Cannot Compete with Real RT?

Because they are just screen-space filters:
effects disappear when off-screen
shadows and lighting are inaccurate
reflections are inconsistent
no physical light behavior
heavy GPU cost with very little benefit

They are purely cosmetic overlays, NOT ray tracing rendering features.


This is why these mods as misleading “Ray Tracing” presets or even outright scams.
They promise to “add Ray Tracing” to games where it is technically impossible, and what they deliver is simply a set of ReShade color filters!
