I am trying to understand how does rendering work on a low level.
In a 2d game if the 4 players are sharing the same view I think the GPU has to render the background once then the 2 players but what if it's 3d 3rd person with 2 seprate monitors will the GPU render everything 2 times ( once for each player ) or will it render the world once and make minor calculations to to show each player's perspective?
Is there way for me to determine the outcome?
