I've tried, numerous graphic settings to see if the shadow will activate. Put the at max and low, but nothing seems to work. Any tips or ideas?
in game screenshots of your graphics settings and upload your graphics_options.xml from Documents\My Games\SimBin\RaceRoom Racing Experience\UserData Andi
You said there are similar issues on Steam forum, but the only thread I found is from 2015. I would try to update GPU drivers and also install DirectX 9 from Microsoft website: https://www.microsoft.com/en-us/download/details.aspx?id=8109
