Patch 2.1.0 — Weather Overhaul

Patch 2.1.0: Weather Overhaul transforms the driving experience in American Truck Simulator. Every road trip is now shaped by unpredictable skies — fog, sudden storms, and heatwaves impact your deliveries as much as traffic and deadlines.
Unpredictable Skies
Dense fog reduces visibility on highways and mountain passes, forcing slower speeds and greater caution. Rainstorms arrive with varying intensity, creating slick surfaces and dangerous braking distances. Extended heatwaves push engines harder and affect fuel efficiency, turning long hauls into true endurance runs.
Road & Vehicle Impact
Weather is no longer a backdrop — it directly changes how trucks behave. Wet asphalt increases stopping distance, high winds push against trailers, and hot conditions strain cooling systems. Each condition requires different tactics behind the wheel to keep cargo safe.
Immersive Driving Physics
Truck handling has been refined to match the new weather dynamics. Tires grip less in heavy rain, trailers sway more in crosswinds, and long climbs during heatwaves demand careful gear management. Adaptation becomes essential for every successful delivery.
Performance & Stability
The overhaul brings realism without sacrificing smooth performance. Weather transitions, sky effects, and road reflections are optimized to keep framerates stable, ensuring immersion on a wide range of systems.
"Now the road itself fights back — weather can be your greatest challenge or your biggest ally." — American Truck Simulator Dev Team
Other Improvements
● Balanced windshield wiper performance during intense storms.
● Improved visibility of roadside markers in heavy fog.
● Adjusted AI traffic behavior during wet conditions.
● Tuned engine wear under prolonged high-temperature drives.
● Enhanced sky transitions at dawn and dusk under stormy weather.
On the Horizon
With weather upgraded, our focus turns to new state expansions, expanded freight types, and more multiplayer convoy features. As always, community feedback drives the journey forward.
