ISSUE DESCRIPTION

Description of the issue:

Since SU5, the B737 MAX on Xbox Series X has become almost unflyable for me because of constant stuttering throughout the entire flight.

This is NOT just about heavy airports or final approach stutters anymore. The aircraft itself now seems significantly worse than before SU5 in terms of smoothness and overall performance.

What I tested:

  • Public SU5 version
  • SU5 beta version
  • Multiple airports and routes
  • Different online/offline traffic settings
  • Reduced enabled content (airports/liveries)
  • Rolling cache cleared and recreated
  • Xbox restart/power cycle
  • Different graphic/network configurations

Despite all this, the aircraft still suffers from continuous microstutters and freezes during all phases of flight. Taxi, climb, cruise and approach are all affected.

What is strange is that before SU5, while the MAX was never perfect, it was nowhere near this bad for me. Since SU5 the performance degradation is dramatic.

At the same time, IniBuilds Airbuses generally perform noticeably better on my setup, which makes this feel very aircraft-specific rather than simply “general simulator instability”.

The biggest issue is that the stuttering is constant enough to completely ruin immersion and make manual flying, especially landing, extremely unpleasant.

This has been tested both on the SU5 beta and on the current public release.

Please investigate the performance and memory management of the B737 MAX on Xbox Series X, because right now it feels significantly worse than before SU5.

FREQUENCY OF ISSUE

How often does this occur for you (Example: Just once, every time on sim load, intermittently)?

Everytime since SU5 (both beta & public version)

REPRODUCTION STEPS

Please list clear steps you took in order to help our test team reproduce the same issue:

  1. Load the B737 MAX on Xbox Series X (public SU5 or beta) at any medium/heavy airport.

  2. Start a normal flight and fly through all phases (taxi, climb, cruise, approach).

  3. Observe constant microstutters/freezes during the entire flight, especially worsening near arrival and landing.
