Several core systems were redesigned to be more modern and user-friendly: Euro Truck Simulator 2 1.38 Release - SCS Software's blog
Alongside the new engine sounds, SCS introduced convolution reverb effects. This technology creates realistic echoes and sound reflections based on the environment. Driving under a large bridge, entering a tunnel, or passing through a dense forest now had a tangible auditory impact. The roar of the engine would bounce off the walls of a tunnel, creating that distinct, immersive rumble that truckers experience in the real world. It was a feature that asked players to drive not just with their eyes, but with their ears.

: Every truck brand in the game received its own unique, branded dealership design across the map, replacing generic shared buildings. Several core systems were redesigned to be more
If the visuals were the "Vision," the was the heart of this update. SCS fully integrated FMOD 2.0 , a sophisticated audio engine that changed everything.
Higher-resolution textures increased VRAM consumption by ~15% (2.1 GB → 2.4 GB at 1080p/Ultra). However, streaming efficiency improved, preventing out-of-memory crashes. The roar of the engine would bounce off
Euro Truck Simulator 2 (ETS2) , developed by SCS Software, remains a benchmark in vehicle simulation and logistics gameplay. Version 1.38, released in July 2020, represents a significant iterative update focusing on graphical rendering, map integration, and user interface refinement. This paper provides a full technical breakdown of the update’s core components: the transition to DirectX 11, the overhaul of German cities, the introduction of new loading screens, and the expansion of the Iberia map foundation. Using comparative analysis with version 1.37, we assess performance gains, visual fidelity improvements, and player experience changes. Findings indicate that 1.38 successfully modernized the engine foundation while optimizing asset streaming, setting the stage for future downloadable content (DLC).
Prior to 1.38, ETS2 retained a DirectX 9 fallback. Version 1.38 removed DX9 entirely, mandating DX11-capable hardware. Benefits included:
