Thanks for the report. Looking at your report, I'm not seeing that many alarming timing problems (yet). Looks like the longest one is a 63 ms ai_model one. A few questions regarding your testing conditions: - How much time since program start had passed since taking these? - Which aircraft did you try. FWIW, I've been testing using the SenecaII-jsbsim. Initially the timing problems aren't that bad, but after about leaving FlightGear running for about 3 hours, I'm getting very significant timing problems, the last one before I killed the program being close to 45 seconds. I got the following timing errors: Subsystem Timing Alert : 12553567 replay Subsystem Timing Alert : 1953303 controller Subsystem Timing Alert : 1955229 environment Subsystem Timing Alert : 6890232 replay Subsystem Timing Alert : 39674 controller Subsystem Timing Alert : 41267 environment Subsystem Timing Alert : 108117 replay I just don't understand what's going on here...
