It sounds like you and rslg have an understanding of how the theoretical physics of supercruise has been simulated in ED, whereas the "supercruise is boring crowd" ( let's abreviate that down to SIBC going forward) don't.. This is one of the reasons I agree with you and rlsg i.e. I prefer scientific explanations (even tho they are theoretical) over the extremely dubious reasoning of the SIBC. Because the SIBC by definition have somewhat limited attention spans, their eyes must glaze over halfway thru your detailed explanations and they give up, posting yet another iteration of their flawed arguments because they cannot think of a logical way of countering your statements.
Supercruise is one of the few remaining artifacts from the early development era of Elite: Dangerous, when Frontier Developments actually cared about verisimilitude in this game. It feels like someone at FD sat down and modeled the “physics” of Witchspace, and created a fictional FTL system that is consistent in Hyperspace, Supercruise, and normal space... if you assume that engine performance is enhanced by the FSD.
Pretty much everything else has been nerfed to pointlessness, can be ignored due to Monty Haul rewards and power creep, or dummied out... all to appease the Veruca Salts of the community. Even Supercruise is a shadow of its former self, losing quite a bit of skill-based game play and actually slowing down hands on flying, in order to speed up hands off flying.
The sounds that would appear when the FSD was under a lot of stress, and your ship was maneuvering hard through the “eye of the needle,” as well as the visual effects from such maneuvers, made you feel like your ship was about to tear itself apart. You can get a hint of what that was like when your in “glide mode” and you make some hard turns.
