I used to have this problem all the time. If you have Nvidia and Intel you'll want to set the game to only use Nvidia. (You'll have to Google it because I don't remember how I did it.) If you don't have both, I don't know how to help. Good luck!

I had to take area loot off for this. Try it if you haven't already.

Just tried a reinstall... still stuck at 87.5%

Not sure where this topic actually goes so if it's in the wrong place... oh well. Launcher keeps getting stuck at 87.5% Already tried getting rid of the bitraider folder and it didn't help.
