I am also intersted. Any chance to get info about FPS test 3 on MBP 16″ with AMD 5500 or 5600 ?

Occasionally I had quite odd sounds from jet engines, but whenever I tried to record those for demonstration, I could not repeat them 8-(

When 11.0 came out, I had several beta versions checked into git using Linux. Actually git was not designed to manage such a large number of binary files, but if you have enough RAM, CPU power, disk space (git basically stores differences only) and time, you could go that way.
I didn’t do it to go back to old versions, but to see what actually changed (usually more than the release notes say).
Among the things I saw was trailing spaces at end of text lines, many empty lines at end of text files, “float” numbers being written with too many fractional digits, causing “changes” that were not really changes, files being renamed, and all such stuff.
On Windows I also have several directories with old and ancient X-Plane versions (like 5), but who really wants to use them?
On current hardware those old versions load amazingly fast, however 😉

And what if the “next update” makes it unusable for your hardware? i.e.: You installed the update and then you realize that it won’t work any more (meaning performance is very poor, and you’ll have to replace the hardware).
I had noticed that for X-plane 10 with my hardware. Wanting X-Plane 11, I bought an add-on GFX card (AMD), but still performance is not good enough yet.

Read a review of a pre-release of Microsoft’s sim, claiming they have 60 layers of sim weather built from real weather data…

If that’s critical bug, what is a machine crash, an application crash or data corruption then?

When you got it from the xporg store, then run x-updater with beta set

For other stores you need to wait that it will be available there as download

Yes. But if you don’t have a working GL bridge, you can’t run.
