yeah you need to use the last official 3D drivers for BattlEye to recognize and allow them. I was disappointed to see this game uses BattlEye as I would probably pick it up for cheap down the road at some point.
so CM unleashed cannot be used but regular CM can be used with old drivers, that is how I played Ubi's Breakpoint in 3D. Unfortunately, I believe Battleye blocks Reshade too? this means no Superdeth3D...which means no ray tracing DX12 + Superdepth3D
Hopefully there's a way to bypass Battleye, it does have DX11...so it could be fixable for real 3D, but I don't know what the interest level is with this one.
Its REALLY annoying how Ubisoft uses anti-cheat software on all of their CO-OP games. Who's cheating in co-op, and who cares?! probably their micro-transactions division is behind it..
