I've used American Road in BeamNG it played ok, but since the latest updates all/some of my mods are broken so I deleted them all. I'll have to re-download some soon. I like the default maps but they are too small to go fast.
Playing BeamNG™ with a mod map American™ Road (HUGE), the APC™ load is at 365 Watt™. And it doesn't really like it by the sound of it.. to be continued.
