Version 1.30, released in late 2017, represents a "golden era" for many mod maps (like RusMap and ProMods 2.25) and older truck mods that were never updated. If you are a modding enthusiast looking to run a specific map combo from that period, or if you want to experience ETS2 as it was before the DX11 lighting overhaul, this guide is for you.
