I don’t know if it has anything to do that I bought my physical copy of Metro 2033 at Amazon Germany, but even the normal troubleshooting route, with the Steam Community, Nvidia or THQ Nordic would result in a working game for me.
A thread in German that was posted recently pointed me to the solution.
So here is what I sent to THQ Nordic, Nvidia and the Steam Community as a solution:
Hi there all, thanks again for going on with troubleshooting with me. Since neither a discussion thread on Steam Boards , nor NvIdia or THQ Nordic tech support could help me. I wanna share the solution which was posted recently in a German thread on this game’s Steam discussion forum: Go to the game properties in Steam and change language from English to German. The game will still be in English by the way but it will run flawlessly.
Why that is no idea. But I wanted to share that the said solution also worked for me! 🙂
