Ready or Not: Best Performance Config for Unreal Engine 4 Stability

The performance issues in Ready or Not often stem from two things: “Shader Compilation” and “Texture Streaming” overhead. When you move through the diverse environments of Los Sueños, the engine constantly swaps high-resolution assets, leading to micro-stutters. By modifying the configuration files, we can increase the texture streaming pool and enable asynchronous rendering updates. This guide focuses on maximizing stability and removing the “hazy” post-processing that can obscure suspects in dark hallways.

Hardware Compatibility & Expectations

• Tactical Realism Players: Prioritizes clarity and the removal of motion blur to make target identification easier.
• Low-to-Mid Range GPUs: Essential for cards with 6GB-8GB VRAM to prevent stuttering during chaotic firefights.
• High-End Systems: Can use these tweaks to force higher LOD (Level of Detail) distances, preventing distant objects from “popping in” during large-scale maps.

Backup and Preparation

Before editing, ensure the game is not running to avoid file corruption.

1. Completely exit Ready or Not and the Steam Client.
2. Navigate to the local AppData directory.
3. Copy Engine.ini and GameUserSettings.ini to a backup folder on your desktop.
4. Use Notepad or Notepad++ for all edits.

File Location

Ready or Not stores its configuration files in the following local directory: %LocalAppData%\ReadyOrNot\Saved\Config\WindowsNoEditor\

Best Config Settings

Open Engine.ini and paste the following optimization block at the very bottom:

[SystemSettings]
r.TextureStreaming=1
r.Streaming.PoolSize=3072
r.Streaming.LimitPoolSizeToVRAM=1
r.SceneColorFringeQuality=0
r.BloomQuality=0
r.MaxAnisotropy=16
r.Tonemapper.Sharpen=0.8
r.OneFrameThreadLag=1
r.CreateShadersOnLoad=1

[ConsoleVariables]
AllowAsyncRenderThreadUpdates=1
AllowAsyncRenderThreadUpdatesDuringGamethreadUpdates=1

Note: Set r.Streaming.PoolSize to roughly half of your GPU’s VRAM (e.g., 4096 for an 8GB card).

Key Parameters Explained

Parameter	Recommended Value	Impact
r.Streaming.PoolSize	VRAM dependent	Allocates a dedicated memory buffer for textures to prevent stuttering.
r.CreateShadersOnLoad	1	Forces the engine to compile shaders before you start, reducing mid-game hitches.
r.SceneColorFringeQuality	0	Disables Chromatic Aberration, removing the blurry edges in your peripheral vision.
r.Tonemapper.Sharpen	0.8	Adds a crisp sharpening pass that makes suspect silhouettes stand out.
r.BloomQuality	0	Reduces the “glow” from lights, making it easier to see through tactical flashlights.

In-Game Settings vs. Config

To maintain the stability gained from these tweaks, ensure these are set in-game:

• DirectX Version: Use DX12 if your GPU supports it; it generally offers better frame-time stability in RoN.
• NVIDIA Reflex: Set to On + Boost.
• Anti-Aliasing: Use TAA or DLSS/FSR (Quality).
• Shadow Quality: Set to Medium. High/Epic shadows are significantly more taxing without a major visual benefit in tactical scenarios.

Troubleshooting & Common Fixes

• Textures Look Blurry: Your PoolSize may be too low. Increase it in 512MB increments.
• Settings Resetting: Ready or Not often resets the config after a “Hotfix” update. To prevent this, right-click the file, go to Properties, and check Read-only.
• Crash on Launch: If you experience crashes, delete the [ConsoleVariables] section in your Engine.ini and try again.

Frequently Asked Questions (FAQ)

Conclusion and Expected Results

By manually refining your Engine.ini for Ready or Not, you transform a potentially stuttery experience into a smooth, professional tactical simulation. You can expect stable frame times during breaches, clearer vision through shadows, and a snappier mouse response. Your focus can now remain on the mission, not the hardware performance.
