Anyone finding on climb out after starting from the gate the whole sim just freezes and is unrecoverable? (can still hear sound but computer is just frozen). Has happened now with me in the Fenix at least 3 times, maybe some other aircraft too though....

Nope....All good here...

Yes I have had that usually associated with the "There is a problem with your GPU etc " error - the sim freezes but the sound continues.  First noticed with the Block 2 Fenix A320 but then got it with the PMDG 737.  This all came after a Windows 11 update so maybe that messed with MSFS2020.  I updated to the latest Nvidia drivers for my 4090 and the sim has run for over 4 hours with the PMDG 737 and no errors, yet to try with the Fenix so we will shall see in due course if things are back to normal.

Yes! Has happened to me multiple times.  Typical scenerio is climbing out of departure to around FL270 to 280.  Just above cloud tops.  Has happened multiple times on two routes, and each time on each route at about the same geographic point.  So common elements are altitude, just above cloud tops, same or nearly same point in route.  Once was a route from Austin, Tx to Indianapolis, at about FL280 on climb out from Austin.  The other was a route from Baltimore to Bloomington, Indiana.  At about the same altitude and also just above cloud tops.  For both routes the freeze, with only sound continuing, happened at approx the same spot.

My system specs are in my message footer.  Of additional note is that for my RTX 3080 I am using the < RTX4*** series Frame Generation mod, and also using the AutoFPS addon.

I tried a different route from Austin to Indy and had no issue.  Cannot fathom why one route would be affected and not the other, given other elements equal.

Thank you for starting this topic.  I thought these were only an issue for me.

I am having the issue at times, consistent for some reason on the same routes at approx the same altitude and distance out from departure.  But I am not getting a GPU error.  Only a freeze with no indication of why.  Again I am using the RTX frame generation mod for less than 4 series RTX GPUs as well as the AutoFPS mod for MSFS.  I am flying Hjet.  I have 800 Hjet hours and can state the issue is not related to aircraft type.  The issue is recent, like inside the past 30 days if not the past 20 days.

I follow steps like that routinely.  Those are specifically for CTD (crash to desktop).  That is not what is taking place in this discussion.  Sim freezes in place with continuing sound.  Can alt-tab to Windows and run other applications, like browser, and alt-tab back to MSFS.  Still frozen in place.  I run no other Windows apps when flying.  Only the FltPlan.go interface for my iPad (have used it for almost 10 years) and the AutoFPS enhancement for MSFS.  Also have in place the FG mod as indicated in my earlier message.

Do you run Live Traffic?  There is a flaw in the current Production Build of MSFS that causes symptoms such as yours due to LT.  SU15 Beta addresses it and fixes it but SU15 is still in testing so unless you are on SU15 Beta I suggest you turn LT off.  AI traffic seems to work fine in Production Build, only LT is flawed.

Thank you.  Did have LT turned On.  Switched over to AI until 16 later this month.  Will see if that cures the issue.

Unfortunately I still have this sim frozen but sound still audible hassle - at least with the Fenix and DX12.  the PMDG 737 seem to behave normally with DX12 but not the Fenix - freezes after 30-60 mins.  However tried the Fenix with DX11 and and no freezes after 4 plus hours.  This is a bit of a bummer as I have been relying on DX12 and FG so that I can have decent FPS with my 9900KF/4090 combo.

Bruce,
Did you see the post about using Live Traffic?  That appears to have resolved my freezes.

i do get very heavy lag and freezing when the fenix loads in and iam in the flightdeck , but it goes away after around 30-40 secs ?

I had a problem where my sim was freezing after alt tab, but all other application worked. It was the hardware acceleration of my chrome browser causing it. Turned it off in settings of Chrome browser, no more freezes. Maybe also be the case with other browsers.
