When I started BeamNG for the first time(installed today), on a brand new gaming computer, I got the message that I missed the x3Daudio1_7.dll (A part of the DirectX). I found out on the internet that this was not a normal, but a present problem among some games. (Like Skyrim, and now BeamNG. I don't know why ). So I thought that I'd share my solution to the problem, since it was quite hard to find. Go to this site, and download the program. It's a program of Microsoft themselves, so it won't hurt you. The program needs no installation, it just runs once, and updates every part of your DirectX.
