The Dirt Mod for Grand Theft Auto 5 fundamentally alters the appearance and texture of various in-game terrains. By using this mod, players can make the ground surfaces look more naturally rugged and realistic, with bumps, stones and other such irregularities. This could be particularly useful for off-road races or simply for creating a more immersive in-game experience. However, it should be noted that this mod doesn't affect the physical properties of the terrain - it purely changes the visual aesthetics. This means that the performance of vehicles or player characters won't be affected; they will still behave as if they're on the default terrain.
