Playstation 5 splitscreen Co-op

Split screen is a memory issue and a performance issue.

A typical gaming PC will have 16+8 GB RAM.

Xbox series X has 16 GB of total RAM, but only around 13.5 GB available for the game. PS5 is similar. That is not great.

Series S has 10 GB total RAM, so even worse. We use half res textures and medium quality settings on S, which manages to fit into RAM while allowing for some memory growth as you play the game for hours. This was only achieved with a lot of memory optimizations to the point we have basically run out of big things to optimize. We can squeeze a bit more, here and there, but diminishing returns.

Performance wise, you have to have a render a different part of the world, which uses a lot more CPU and GPU.
