How will classic mode work during splitscreen?

Will it change both screens if one player switches or will it only change his screen?

I’m gonna shoot for both players. Think filters for forge… it’s just like that except it’s a graphics filter.

I would say they are going to do something that allows both players to have different modes. The effects in Forge are only map based, that’s why they change it for every player, that’s their intention. The classic mode is engine based, as the game already runs two engines at one time, and the graphics part of the engine is probably transmitted to both screens separately, this would allow one player to switch to classic mode without changing it to the other player. It’s all up to how their engine structure works.
