The blur in the first video is a post process cinematic effect that is over done and utterly unnecessary. Any pilot that had vision that blurry would have been pulled from active duty.
As to the submarine sequence...
Absurd. No submarine that was attacking an enemy task force would be actively pinging its sonar. It would give away their presence to the enemy escorts.
Someone has seen too many Hollywood movies about the war and thinks that's how a simulator should be.
