Increases FPS to the absolute maximum, significantly reduces stuttering, and improves game smoothness without destroying the gaming experience. This mod is focused solely on performance optimization. Visual quality, especially at long distances, will be noticeably reduced to achieve maximum smoothness and increased FPS.

Features:

Extreme FPS boost – removes unnecessary objects and significantly reduces vegetation, greatly improving FPS;
Advanced fog system – adds dense fog closer to the player, significantly reducing rendering distance and increasing performance;
Optimized draw distance – minimal rendering of distant objects to save GPU and CPU resources;
Sharper weapons and scopes – slightly increased rendering quality for weapons and sights for an improved aiming experience;
Reduced Unreal Engine visual artifacts – minimizes typical Unreal "checkerboard" artifacts for a smoother visual experience.

Visual changes:

Vegetation significantly reduced (trees, grass, bushes minimized);
Object rendering distance significantly lowered;
Dense volumetric fog added to mask distant object pop-in and improve FPS;
Minimalist shadows and lighting for performance optimization;
Better weapon and aiming sight clarity without FPS loss.

Performance impact:

Expect a significant increase in FPS (up to 50-100% more FPS), especially beneficial for low to mid-range gaming systems.

Recommended in-game settings:

Set graphics to low or medium;
Disable Ray Tracing, Lumen reflections, and other intensive settings;
Set resolution scaling to around 70-80% for the best balance between FPS and visuals.
