PMDG_777X.DLL.

PMDG_777X_3.DLL

Somehow your reply got embedded into my post, so I lifted it out of there.

 

I agree......it would not make sence for this 777.dll to be the actual 777.dll that makes the PMDG777 work.

 

But then, can you show me the real 777.dll ?

I found no other, and I am pretty sure I had to click ALLOW for some PMDG777.dll after I installed the PMDG777.

 

Look a bit up on my post #14. Should read PMDG_777X.dll

I Was looking for something and did not see untill today that you inserted even more stuff (post 14) into my post.....

 

Bit difficult to see like that.....but thanks for explaining.

 

Ok so now we know where the real 777.dlls are and that the Ops Center .dll are not a part of the simulation.

There's also a PMDG_777X_2.DLL. All three are in the Gauge folder. These are the ones that provide the code for the  aircraft systems. There is also DLL that is loaded at FSX loading called the PMDG_Interface.dll and that is located in the PMDG\DLL folder. This one doesn't appear to be required for flight. It's main purpose is to allow you to load and save panel states when you save a flight. As such I don't load it with no ill affects, (Just I can't save a flight) I do this because I'm running on a Vista 32bit system (Don't ask! :lol:), and I need all the VAS I can get, so I don't load  any unnecessary DLL;s at startup (Using ManualLoad in the dll.xml file). Generally it works fine. I wouldn't recommend it though, unless you really have to, like if you run on a weak 32bit system like mine!!

 

I tried the sound_quality tweak, and it does make a difference on my system, both in FPS, and reduced stutters. Sometimes now I hear a clicking sound intermittently (So far not with PMDG aircraft), but it doesn't last long, so it's a tradeoff I can live with!! Thanks to the OP!!

Hello All, For bout 35 flights using the T7 I had couple of freezes only!............. because I was departing from a negative altitude airport (EHAM) or perhaps to unrecognized European way points name...Not sure. Before that the T7 and other planes were nearly not flyable.......It's defiantly related to computer resources so if you reduce the bars or chose a 1024 textures only or removed shadows it will defiantly help but still will happen.
 

I applied series of fixes that involved deleting fsx.cfg completely.......And it's working for me.....If some one interested in trying it......... please let me know (at your own risk of course). 

 

Important not: the kind of error of freeze is unique ......It's not CTD or OOM.....Usually happens 1-2 hours in flight, It's a freeze where engine fuel is still consumed, it usually takes from seconds to half an hour or so, it could happen once or many times during the same flight, when it's gone the plane and SIM responds normally..........Any different symptoms it could be something else. 

Are you therefor saying a totally "untweaked" fsx.cfg reduces the problem, Alaaar?

was wondering if users  that are experiencing these freezes  have  the same video card  and those not  having  freezes  have another video  card. iam using  a amd  card and havnt had any kind of  freeze or  any issues with pmdg  aircraft at all

Yes, seems video related, but I've got NVidia and never seen these freezes, got "untweaked" fsx.cfg too (got some applied but only those that don't cause issues).

well there goes my idea out  the window B)

GTX 580 here Pete, no freezes. Very little in the way of tweaks.

Hello Steve

 

I did the following:

 

·         I deleted FSX.cfg

·         I use CCleaner every other week

·         I used FS_Registrey_Repair from Flight 1 like every month

·         I used from AVSIM FSX CTD Guide, I increased Heap                            Limitation, tool frohttp://support.microsoft.com/kb/947246

·         I added the file UIAutomationCore.dll V. 6.0.6001.1800 to FSX             root

I added:

[bufferPools]

BufferPools=1

           PoolSize=10485760

          RejectThreshold=524288

          [JOBSCHEDULER]

          AffinityMask=14

          [Graphics]

          HIGHMEMFIX=1

         TEXTURE_MAX_LOAD=4096

         [Display]

         WideViewAspect=True

         TEXTURE_BANDWIDTH_MULT=80

         [Main]

         FIBER_FRAME_TIME_FRACTION=0.1

 

I hope that will help 

Hi Alaa,

 

I used a thunderstorm and heavy rain for testing.

 

I have a GTX 680 with a i7 3960x. I have been trying your bufferpools section. I found it consistently reduces my fps by at least3 fps, this is with only a back to back test of unlimited fps, starting the stock B350 on RWY12 EGFF.

 

Going to fixed 19 fps the HIMEMFIX=1 creates fps drops with lightening, and makes the sim controls lumpy depending on what's going on.

 

I can't see there's anything there to freeze the sim.

 

All the best

Steve

I had freezes in my PMDG 777 also.I noticed that i start having problem after bitdefender antivirus installed... So i just uninstalled the bitdefender and the problem is fixed!Now i'm using ESET Smart Secuirity.

OMG it works.  i changed fsx config file to sound lod=1 and sound quality =2, no freezes on a 12 hour flight from SCCI to KAUS.  sAME TRIP YESTERDAY 4 8 TO 9 MIN SCREEN FREEZES i GAVE UP AT THAT POINT.  tHANKS FOR THE HELP.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

omg it works sound lod=1 sound quality =2 changed  FSX config.  Just finished a 12 hour flight from SCCI to KAUS and no screen freezes.  yesterday I tried the same flight and had 5 screen freezes at 9 minutes each so I aborted the flight.

I am a happy pilot.  Thanks for the help.
