Do I have to use surround for triples to work in this sim? I used to play Raceroom a while ago but since moved onto other sims that don't require surround. Hopefully there's a way because honestly running surround for one sim I rarely play seems like way too much of a hassle
As far as I know, you don't need it. You can either setup your triples with startup parameters (there's a guide here on the forums) or you can use the new beta UI and setup your triples in game. Use -webmenu launch parameter in Steam to enable this UI.
There are ways around not using nVidia surround, just do a search, I found it before, as I tried it but I had the opposite issue, some software I use needs surround, so never stuck with it.
