Hi, I don't think it is the problem in my case: the Sysinternals Process Explorer shows that ale cores are used. The AffinityMask setting is as you recommend in the tables. I found that my FR goes up to 16-20 if I run full screen. That is acceptable for me, although I still would like to understand the root cause of the problem.

Hello, I have a similar problem and I have not been able to find the cause. I did execute all tweaks recommended by PMDG including Venetubo's FPS = 8 to 12 for VC and a bit higher for outside view, even is FS in in pause mode Added temporarily 4 GB of memory: no difference Moved all sliders to the left: no difference Changed the GPU processor and memory speed: no difference I have checked the system with System Internals Process explorer. Results are as follows:CPU use in paused mode 20% in flying mode 30-65% GPU use: 12% Memory: 1.1 GB GPU memory: 482 MB, shared 42 MB, committed 670 MB So the only thing that runs towards the computer limits is the GPU memory. Can that bet the problem?

Hi,I must be doing something wrong.I have tested with a registred version of FSUIPC (FS 2004). Installation goes OK, but I don't see any difference whatever I do.

Hi,I have done a few flights now (EGLL-EHAM-EGKK) with SU 1.2 AIRAC 312/313 and summer scenery, no Cessna start, FMC on: no problems anymore.

Tom,I am afraid that this doesn't work for me (see my 2nd and 3rd attempt, that is about what you did)Tonight I flew back from EDDM to EGLL with PMSG 737 1.1, no AIRAC, winter scenery - result was a crash (this time with the famous "Do you want to inform MS..." screen) 60 nm before BUB.I reloaded the autosave, restarted - immediate crashThen I changed to the summer scenery: no problem anymore

Paul,In the folders you refer to I only find files with names State.CFG. I deleted them. That in itself made no difference. Subsequently I changed to a summer night flight and then it worked.Apparently this issue is location dependent (as I saw in a few other mails). I had it happen on a trip from LFMN to EGKK on the UM733 between Barro and Oktet, 7nm inbound Oktet.I have Airac 312 active.It also worked for me when I started with the Cessna and then switched to the 737.

That's interesting, I had it on a similar route:LFMN-EGKK via UM733 between Barso and Oktet 7nm inbound Oktet.LNA-VNAV mode, AIRAC 312 active.

I have midair crashes back to desktop with update 1.2 that I didn't have with 1.1. I tried removing the AIRAC altogether, but I still get crashes.So there must be something else as well.

I had exactly the same problem in mid-flight, I never had it with 1.1 with an otherwise identical configuration. I tried to completely ininstall and subsequently reinstall PMDG 737 1.2, but no luck. When I continued the flight from autosave it crashed within a minute.See my configuration below.
