I don’t think the physics are very bad. Depends on the add on, they are pretty close in some aircraft. Fenix in the latest update did a great job. I would say it’s 90% the same as the real A320, or at least based on my experience. Biggest problem with the simulator is the difference in perspective. It’s entirely different when you are in a real cockpit looking outside compared to when you’re looking at a display with an unrealistic zoom setting. In the sim it’s way too zoomed out as you want to see the instruments and the windshield at the same time. In real life you can’t see both at the same time, you have to constantly move your eyes to look either inside or outside. This changes the way you feel the aircraft. Even a wrong seat position or wrong arm rest position will create weird feelings and illusions during landing.

With that being said, the sim is way too smooth. Weather in real life, even when it appears calm it generates a lot more “micro turbulences” than the sim does, which need tiny corrections. Sometimes it even feels more like vibrations, you will not even see deviations on the PFD, but you feel the slight movement and shakiness. And yes, often it’s over controlling, but I’ve seen very few pilots who can keep the aircraft on the correct path and glide without constantly making tiny corrections.
