First make sure it's installed correctly, after that, make sure in global processor definitions, REVERSED one is -1. Also make sure you did get RTGI, that is a manually installed effect that cost money.
I installed reshade and I've activated a setting that just crashed my BeamNG. I installed Reshade directly from the website, but I checked my downloads and Reshade wasn't there at all, only the downloader. I can't start Beamng to turn it off either, it just crashes. I can't find it anywhere in my files, and I have no idea what to do. Any help?
Go redownload ReShade from the website, find BeamNG then use Uninstall instead of Install. All you need is in the installer.
