Farming Simulator 25: Best game.xml for High-Resolution Terrain

The primary objective in 2026 is to optimize Displacement Rendering and Tessellation, which govern how the soil looks when manipulated by heavy machinery.

File Path & Setup

1. Navigate to: Documents\My Games\FarmingSimulator2025\game.xml
2. Open with: Notepad++ or any XML editor.
3. Pro Tip: If you see <gpuPerformanceClass>auto</gpuPerformanceClass>, the game is still auto-managing your settings. Manually changing a setting in-game and saving once will populate the full list of coefficients for you to edit.

Optimized “Topsoil Detail” Configuration Table

Parameter	Recommended Value	Technical Purpose
terrainLODDistanceCoeff	4.000000	Extends the high-detail ground texture to 400% of the standard range.
volumeMeshTessellationCoeff	0.5	Higher Quality. Lower values increase geometric complexity on fields.
foliageViewDistanceCoeff	4.000000	Renders crops and grass far beyond the usual 200% slider limit.
lodDistanceCoeff	4.000000	Prevents trees and buildings from swapping to low-poly models too early.
tyreTracksSegmentsCoeff	8.000000	Doubles the detail and longevity of tread marks in soft soil.

HowTo: Engineering the Ultimate 2026 Farm Visuals

Follow these GameEngineer.net technical steps to eliminate terrain “blur” and asset popping:

1. The Tessellation Inverse: Unlike other settings, volumeMeshTessellationCoeff works on an inverse scale. 1.0 is medium; 0.5 is high. Be cautious going below 0.25, as this forces the GIANTS Engine to calculate millions of polygons for field ruts, which can exponentially increase map loading times ($T_{load}$).
2. Foliage Render Circle: To stop crops from “appearing” in a circular radius around your tractor, set foliageViewDistanceCoeff to 4.0. For RTX 50-series or 4090 users, you can push this to 5.0. Note that this is the heaviest CPU draw-call ($D_{call}$) setting in the game.
3. Displacement Quality: In 2026, the new Displacement View Distance is crucial. In the game.xml, ensure this is scaled relative to your terrain. If the soil looks flat at 50 meters out, ensure your terrainLODDistanceCoeff is at least double your viewDistanceCoeff.
4. Shader Cache Warming: After editing the .xml, delete the shader_cache folder in the same directory. This forces the engine to re-compile terrain shaders using your new high-res coefficients, preventing “rainbow” texture glitches.
5. Multi-Terrain Angles (MTA): If you are a modder or map-maker, these .xml tweaks pair perfectly with 32-angle terrain scripts. High-res terrain allows the 32-angle soil textures to transition smoothly without the “blocky” artifacts seen on default maps.

Technical Explanation: Geometric Complexity ($G_{comp}$)

In Farming Simulator 25, the terrain isn’t just a flat plane; it uses Parallax Occlusion Mapping (POM) and Tessellation. When you plow, the engine generates a 3D volume mesh ($V_{mesh}$) that follows your tires.

By lowering the volumeMeshTessellationCoeff to 0.5, you increase the Subdivision Rate of the ground. This means the ruts left by a John Deere 9RX are physically modeled with twice the geometric detail, reflecting light and casting shadows based on the actual depth of the tread ($D_{track}$). This turns a simple “texture change” into a true 3D surface, though it requires significant VRAM bandwidth to stream the resulting vertex data.
