If you're able to build from source and don't mind using development looks like the built-in profiler, it would be interesting to see comparison of both builds - ideally using a simple test case with everything else disabled - you could use a pre-recorded flight and/or a flight recorder type to come up with a "test flight". From our standpoint, it would help tremendously if all features that don't seem to have an effect could be completely disabled, including complex aircraft and scenery/locations. In other words, if you can reproduce the problem using "bare" minimum settings, the resulting log file will be much easier to process. | If you're able to build from source and don't mind using development looks like the built-in profiler, it would be interesting to see comparison of both builds - ideally using a simple test case with everything else disabled - you could use a pre-recorded flight and/or a flight recorder type to come up with a "test flight".

While unlikely, it would be great if the issue could be reproduced that way - but more likely than not, you'll have to re-add a few features and change a few settings, e.g. by using a different location. | While unlikely, it would be great if the issue could be reproduced that way - but more likely than not, you'll have to re-add a few features and change a few settings, e.g. by using a different location. | ||
Like I said, you could then use the replay system to create an test flight than can be easily reproduced - to get going more quickly, you can also use the built-in route manager to create a simple flight plan and fly the whole thing on autopilot: | Like I said, you could then use the replay system to create an test flight than can be easily reproduced - to get going more quickly, you can also use the built-in route manager to create a simple flight plan and fly the whole thing on autopilot: [[Instant Replay]] | ||

If that's something you'd like to pursue, feel free to get in touch - it is definitely a worthwhile thing, even regardless of any OSG specific issues, as it will also help with unrelated performance issues. | If that's something you'd like to pursue, feel free to get in touch - it is definitely a worthwhile thing, even regardless of any OSG specific issues, as it will also help with unrelated performance issues. | ||
