Airport is pretty good overall but there are texture issues and bumps on taxiways and runways. The threshold marking of RWY34L is currently messed up and extremely bumpy. Besides that it's great quality and performance wise.
I have this and the pacsim rendition of RKSI. Both are great airports but if you want better quality get PacSim and if you want better performance get le Aero.
Runway is a little too bumpy for a 0.0 gradient. Texture resolution is way too low so you cannot even see the ICAO type markings at the gates. It's flyable but definitely doesn't match the 20-ish dollar price tag.
