This problem was raised a few weeks ago, and one of the forum managers closed the topic as if the issue had been fixed. We have had two updates for A350 since then and the issue still persists. Is anyone testing the product on Xbox before sending out updates?

I have the same issue. Looking forward to what they have to say!

Hello iniBuilds Team and Community, I am writing to express significant disappointment regarding the performance of the iniBuilds A350 and A340 airliners on the Xbox Series X platform in Microsoft Flight Simulator. The Core Issue: The aircraft are virtually unusable during critical phases of flight—specifically during taxi, takeoff, and landing. At these moments, the sim experiences massive stutters and freezes (sometimes 1-2 second pauses) which completely ruins the immersion and playability, especially at major add-on or default airports. Given that takeoff and landing are the most engaging parts of simming, this makes the products feel incomplete. The Performance Discrepancy: What makes this issue particularly frustrating is the comparison to other complex, "study-level" add-ons. Products from developers like PMDG (e.g., the 737 and 777) run consistently well on the same Xbox Series X hardware, maintaining smooth frame rates and stable performance even at demanding airports and during finals. This begs the question: Why is there such a massive performance gap between the two developers? Is this a fundamental difference in optimization techniques (such as how the underlying code is compiled—C++ vs. JavaScript to WASM) that severely impacts console performance? I would appreciate a clear, technical explanation as to why iniBuilds products, which are otherwise highly detailed, seem to be such heavy resource hogs, particularly on the ground. Refund Inquiry: As the poor performance makes these airliners effectively useless for their intended purpose (long-haul operations into realistic airport environments), I must inquire about a refund. Since this was purchased through the MSFS Marketplace on Xbox, what is the recommended procedure? Should I contact iniBuilds support directly, or must all refund requests for technically unusable products be routed through Microsoft/Xbox support? If an immediate fix is not feasible, I would like to initiate the refund process, as I cannot justify keeping products that perform so poorly during core flight operations while competitor products run flawlessly. Thank you for your attention to this serious matter. A frustrated Xbox Simmer.
