I’ve done multiple controlled tests at Inibuilds HKJK using a 5090 + 9800X3D + 64GB RAM, 4K Ultra, TLOD 50 / OLOD 150, and frame gen off (standardized gate, weather, time of day). Here’s what I’m seeing:
PMDG 777-200ER: 65–70 FPS
Fenix A320: 56–70 FPS
iFly 737 MAX 8: 50–65 FPS
IniBuilds A350-1000: 42–43 FPS
That’s roughly a 35–40% performance gap between the A350 and the rest of the top-tier market. I’ve repeated the tests under different conditions, and the results are always the same — even when using reduced LODs or 4K textures.
I really hope the team makes performance optimization a major focus in upcoming updates. This aircraft deserves to be more than just beautiful — it should run like a premium product too.
