Ultimate engine optimization (anti-stuttering - improved performance - reduced latency - enhanced clarity - lossless image quality)

The ultimate "Engine.ini" modification for the "Infernal" engine, designed to eliminate most lags, improve performance and stability, reduce input lag, and improve picture clarity without losing any visual effects.

Ultimate Engine Tweaks

🎮 **Welcome to the ultimate engine optimization module for "Infernal Affairs: Lost Feather"! **

After several months of testing the UE5 engine, I will share the final **"Engine.ini"** modifications carefully customized for this game.

✨ Mod Targets

My goal is to integrate as many optimizations as possible (covering CPU, GPU, RAM, SSD) to achieve the following results:

• 🚀 **Eliminate most lags**
• 📈 **Improve overall performance**
• ⚡ **Reduce input lag**
• 🖼️ **Improve picture clarity** (such as optimizing film grain, motion blur, removing chromatic aberration, optimizing DLSS/FSR oversampling and anti-aliasing, reducing ghosting and flickering)

**All optimizations are done without loss of visual effects, introduction of glitches or crashes! **

🔍 If you want to know **exactly** what each optimization does and its combined effect, check out this detailed description.

🤔 How to choose between "VRR" and "No VRR" versions?

• **VRR** stands for variable refresh rate, corresponding to NVIDIA's G-Sync or AMD's Freesync.
• You need to check if it is enabled in your NVIDIA/AMD control panel** and** display (monitor/TV).
• ✅ **Both Enabled**: Please use the **"VRR"** version of the mod.
• ❌ **Not Enabled**: Please use the **"No VRR"** version.
