Fantastic News Thank you


Great news, thanks!

Is there a change-log/release notes, or is it just as mentioned the CTD fix and navdata update?

Many thanks

Is there a change-log/release notes, or is it just as mentioned the CTD fix and navdata update?

Those are the only changes in this build compared to the initial pre-release testing build.


Thanks for confirming :slight_smile:

if this doesnt fix those blue purple patches, i will be ■■■■■■. I updated my driver from a safe one just for this news today.

Exit and enter in insider programms, restart PC many times, exit and enter to account, but updates don’t see. XBOX and MSStore give me version (

I can’t get it to update tried restarting signing out and back in.

Maybe its not out yet.

The new build isn’t available yet. Per the OP, it will be deployed later today.

I assume that’s one of the things those affected should be testing :slightly_smiling_face:


Regarding the updated AIRAC, I have an issue now where I don’t have any nav data at all. I’m using NAVIGRAPH and have AIRAC 2112 rev 2 installed, yet I have no nav data in the sim. I’ve tried removing and re-installing but still nothing. Is there something up with the underlying database? Any ideas on how to fix or would this update sort this issue out?

Glad to hear about the driver CTD remedy. Have been using 497.09 for several days with no CTDs but if it save just one sim, then it’s worth it. :+1:


I’ve updated to and stil experiencing CTDs. What else can we do?

I’m still not seeing it.

Can you please confirm you’re actually running the build? We’re not showing it as available to testers yet on our end.

I will update this thread once I have confirmed it has been released.

I am not running the latest nvidia driver (I am using 496.49) so I don’t have the CTD issue but the update is definitely released for me here in the pacific time zone in the U.S. (as of 6PM pacific time):


Yes, I just received word the new build is now available.
