I can confirm the same experience — I’m also seeing severe performance issues. I’m getting around 8 FPS at major airports and 12–16 FPS in the air. For comparison, I fly the PMDG 777 with a stable 50–60 FPS, even on the ground at large international airports.
In its current state, the A300 Premium version (which is the only version I own) is unfortunately unusable for me. Over time, I have lost confidence that this aircraft will ever be optimized to a level where it becomes truly flyable.
As a result, I have not purchased any further aircraft from iniBuilds, as I currently lack the trust in future improvements.
