So I've dug around in the past, and thought I found some solutions. But searching now isn't leading me to anything concrete.
Any time I try launching my game on 3440x1440 resolution, the "cannot init 3d3 OR grf file has problem" shows up.
I have a Predator X34 monitor, and was wondering if anyone has figured out a way to resolve this error. Would love to play this game at this full resolution, and have seen screenshots of it.
