In my opinion, War Thunder's stormy weather setting nails it perfectly in terms of sea roughness - it offers a balance which feels realistic without being overwhelming, allowing ships to sail through it convincingly. Obviously waves can be absolutely massive, but accurately simulating a ship's interaction with them as it drops down from a high wave is probably challenging to do, and it might not be feasible to implement in a flight sim if it requires too much work and effort. I remember several years ago, War Thunder stormy weather setting featured larger waves, but at times, the entire ship would submerge and then reappear as if nothing had happened, and it looked.. pretty bad and unrealistic. However, in the current version, shown the in the video below, they have scaled back the intensity and it looks much better.

But since CP will be running on the UE5 engine... I am extremely hyped! 👀
