TBH I'm a bit torn over this mod;
On the one hand, it is subjectively a great-quality track mod. The textures, lighting, etc. leave little to be desired, and for once I don't feel the need to download an extension to get proper lighting and brightness at night.
On the other hand, neither the actual track-surface layout nor the trackside details and decorations are terribly accurate to the real circuit. The T4-T12 sequence feels somewhat off with both the track layout and the way the walls are shaped and positioned, and T13 almost entirely flat instead of the significant camber the turn has IRL + there is also a bump/sudden dip heading into the corner that is not present IRL (just to name a few examples). The mod is also almost completely lacking all of the pedestrian overpasses/'buildings that pass over the track' that really give it its atmosphere. I downloaded the original version of this mod way back when, so I do understand that there's a certain degree of "work with what youve got" as far as updating the mod instead of making an entirely new one, but the differences vs IRL are fairly significant, even if not the end of the world.
TL;DR: All-in-all a very good mod, held to the high standards of this mod author and with the most recent update to the mod it is among if not THE highest *quality* mod of this circuit, but as the mod was, IIRC, originally one of the very first versions of the Jeddah Corniche circuit available on any consumer simulator, it has a few inaccuracies compared to how the real circuit is today. These inaccuracies don't detract from the quality, so if that's fine with you then you can't go wrong with this mod of the Jeddah circuit
I really appreciate your in depth review.
I am aware the track is lacking a lot of it's verticaliy in terms of it's architecture. This is something I will aim to sort in a future update.
Watching the F1 this weekend, I now have a better understanding of the geometry for the banked corner, and will also rectify it.
Again, thanks for the time, you've raised some valid points and I will be sure to act upon them. Perfect!
