Yeah it’s just harder and potentially less performant. There are different levels—deterministic across the same architecture, different architectures etc… The simplest example I can think of is being deterministic across different frame rates. Imagine you move a player by adding x to it’s position each frame. You adjust x based on the frame rate so that you don’t move faster on a faster computer. So on a computer tuning at 30 FPS you move 10 pixels each update. But on a computer running at 60 FPS you move 5. You have walls that are 6 pixels wide. On the 60fps computer it works fine, but on the 30fps machine you can teleport through the walls.
