One issue is that there are no "fly-over" waypoints, which are part of many SIDs and STAR. All waypoints are "fly-by". Especially at turns >120° the FMC cuts the corners. (Seen in your picture at WP CF07 and TUC329)
This is a top 5 issue for me to get more realism, and i hope they will address it in V4.5. It would be OK to be able to select specific wayponts in the FMC as "fly-over". I guess adjusting the navigraph-data would be too much work.
