OOM has returned in 3.1

You can also try changing these in your Prepar3d.cfg:

[TERRAIN]

UseGlobalTerrainView=True

[sCENERY]
MaxRegionsPurgePerFrame=32

Warning: MaxRegionsPurgePerFrame can have a negative impact on FPS and might induce stutters. Default value is 16 for P3D, I believe this value was 4 in FSX.

EDIT: I should add that if your system is having a hard time purging terrain tiles (removing them from memory) due to other settings (like FFTF too low) then VAS can grow and grow and never get properly released. That's why it's important to balance your system and not deem FPS performance as the "best" option. For example if your system is running Unlimited and you have a 60Hz refresh but your frame rates are always below 60 FPS, then you are maxing out processing which means that will be hard on the purge process (dumping tiles from memory).

 

Hey Rob,

 

I was going to post a new thread regarding MaxRegionsPurgePerFrame.  Do you know what the max limit is?

I've been suffering OOM errors in P3D V3.1 with Flysimware Learjet 35A. I recently changed my texture with those of REX4 and the performance has suffer.

I went and deleted the Shaders folder and now it is good again and my VAS hovers in the low 1Gb.

Isn't there any programs that can monitor VAS and give a warning when you get below a certain amount? And at the same note, is it possible to save any flight with any aircraft when the warning comes, and be able to reload the flight with all settings as it was just before the VAS warning. If it would be possible to restart P3D and load the flight so there's "nothing" in the VAS memory to cause an OOM, and make it possible to end a long haul flight succesfully. Is this possibe in any way, and if not, Why?

Nicely done Bob.

Thanks for the HU. Did not know they had that patch. After flushing the Shaders folder, VAS seems pretty steady at around 1Gb left.

One of the things I like about the FSUIPC VAS setup is the fact you can tick the "log" option and, when you shutdown P3D, you can open up the FSUIPC.log and it will show you the amount of VAS used when P3D was loaded to the setup screen and then loaded when you start up the flight.  I use it for testing various aircraft/scenarios.  For instance with real weather, w/o weather, with the PMDG 777, with the Phenom 300, etc., etc.  I can save the fsuipc.log to something like KSTL to KORD_PMDG777.  Then I can see who's eating up what and where.  The FSUIPC also has a warning system that tells you when you are running out of VAS and will show this information in the fsuipc.log too.  My VAS monitor is located at the top of left corner of my monitor and I can monitor the VAS usage constantly.  It works for the freeware version too!

I was told the limit, but after looking thru my notes I didn't write it down.  Experiment, if changing this value has no impact then it's likely one's system is keeping up with the purges and one will need to look elsewhere for VAS issues.

 

This value can be more useful on long duration flights at higher altitude where P3D has less work to do.

 

Cheers, Rob.

I use ProcessExplorer because FSUIPC has a different amount of VAS remaining and it seems like the ProcessExplorer is more accurate on my system.

P3D V3.2 has addressed a few issues in V3.1 that could cause OOMs ... 

 

Rob, are you a v3.2 beta tester?

Hi Rob,

 

Can you please elaborate on this one?

Thanks a lot.

I tried Process Explorer months ago and the only change I noticed was stutters in my sound. I put it in the recycle bin.
