Hi, really not sure what the source of this problem is but I'll try.

Yesterday I flew KEWR - EDDK about a 7 hour flight if I remember correctly. first part of the flight was completely fine however just before T/D the sim started to freeze for 30-40 seconds, with the feeling of a CTD being unavoidable however after 40 seconds it came back to life for a couple of seconds and then back to freeze again. did this something like 10 times before I gave up and closed p3d.

This has never happened before. have flown longer routes without any freezes. The thing that has changed is that I have updated P3d to version 4.4  and updated the 747-8 to the latest version.

Just wanted to know if anybody else has seen this behaviour? 

I have not changed any settings as automatic save or anything so thats most likely not the problem.

 

This is quite a common thing unfortunately, it's referred to often as a 'long frame' where the simulator appears to crash but is actually functioning.. It's most frustrating when it happens on short final.  I don't know the cause, I had always assumed it was to do with how P3D handles the caching / loading of scenery.  Not a lot that can be done about it I am afraid other than remove all scenery from the sim or wait for the problem to be tackled by LM (assuming that's where the problem lies).

Apologies that's not much help, but you're not the only one, this happens to me a lot too, I just 'ignore' it the best I can.

Hi Craig, thanks for your reply.

I dont think this is the same issue, perhaps related though... The problem was that the freezes kept happening with like 10 seconds interval... so running for 10 seconds, then freeze for 40 seconds, then running fine for 10 seconds then freeze.. so it was not a one time thing...

Are you 100% sure nothing changed regarding Automatic save? For example I installed a new version of the Acars for my VA and the settings reverted back to the default where it has Autosave enabled and could see the behavior you are describing. Removed Autosave and problem fixed

Thanks, No Im not 100% sure, however this is something that I have never had enabled so I would be surprised. But sometimes life is surprising;-) I will definately check this.

Specifically I have flown the newest version of the 748 from Orbx YMML to Flightbeam KSFO (about 16 hours), with several add-ons running (ASP4, UTL 85%, STB, GSX, RC4, NAV Charts, Orbx global ect...), very high P3D 4.4 settings, locked at 20 FPS. I had no performance issues...smooth the whole way.

I never specifically have had this kind of issue (30-40 second freezes) in P3D or FSX.

I personally did a full clean install of 4.4 and reinstalled all add-ons, as is my custom.

Paul,

If you don't mind, what are the p3d.cfg, and nvidia settings that will allow 20 FPS "smooth the whole way"?

Would you be so kind and share those settings, please.

Hi, Where is this setting at?

Thanks Kyle, however I'm not using the registered version of FSUIPC so I don't have that menu, there is a button for "normal defaults". Is the Auotsave function enabled in the unregistered version?

 

Thanks,

Not to my knowledge.

I cannot imagine why you would be asking me this, your system is much more powerful! You should be able to keep a steady 30 FPS, perhaps 60.

Just so you know, I have been computing since the very early days, and I have had like 14 PC systems, maybe more, as I give them away too. I have many older systems running even now. I say this because I know how to keep a very clean and efficient machine, I learned the hard way long ago. I bought my first PC for the sole reason to fly MSFS version 3. I saw the FS3 demo at a Radio Shack store and I was determined. 

I'm not claiming to be a "guru", but you will only rarely ( probably never) see me here or anywhere with troubles of my own because of my PC's. I learn from others successes and mistakes. Researching through decades of trial and error.

Using my cfg or NV settings may or may not help you, because there are a myriad of other system (Windows & BIOS) settings, add-on settings, system utilities, and others that can play a part in P3D performance. A book would have to be written to cover it all. Never-the-less my settings you requested, I truly hope it helps you:  

My Nvidia CP is default except for Max rendered frames at 4 and Power Management Mode at Prefer Maximum

Thank you Paul,

The reasoning behind is that if I lock my FPS at 30 I get stutters with complex airplanes. In this way I can compare with what I have.

For example with FsLabs and PMDG if I set for 30 FPS I'm hit with stutters versus unlimited where I have none.

I've also always had struggles with smoothness when setting a specific TFR in MSFS/P3D. 

Running with TFR unlimited and frame rates limited by VSync to a 30 Hz monitor has been the magic pill for me for the last several years, starting with P3D v3.
