[2019] Crossfire not supported?

CrossFire isn't something we're actively restricting, but also it's not something we've plan to allocate resources to at this time. Lot more things to tackle which effect a larger number of players.

We've done some recent optimisations that should help 4k, but overall the game is pretty demanding and we need to make improvements across the board. We've got some things in testing at the moment thanks to some work directly with NVidia which should result in better GPU and CPU perf, hopefully, we'll be able to roll that out this month.

Those specific changes which were made on that beta branch have been incorporated into the live game, though it might be that we'll end up using the branch again for these additional changes, we'll have to see how dangerous they are
