OOM errors revisited

Recommended Posts

Has there been any further development on OOM management/prevention?  After a month away from flightsim, I'm going to fire P3D up again and see how things go.  

 

Out of interest, what VAS utilities are people using to monitor this, if at all?

I posted a thread about this on Avsim just now about a  discussion on Facebook yesterday, where a few users tried this program and it ended the OOMs they were getting on every flight. I don't get OOMs at all, but I downloaded the program and like the features and the basic program is free to try, easy to install, and gives you a ton of information on what your CPU and memory is doing. It even has a gaming mode and "memory trimmer".  https://bitsum.com/processlasso/

Hi Bob I remember reading about this a few months back when it hit the Avsim forum pages. From what I recall, it got a lukewarm reception from PC gurus. But frankly, I'm willing to try it. It can't be worse than the frequent OOM's I have been getting with P3D lately. I am still perplexed as to how I went from a stable, frequent use, no OOM state to one where I was constantly getting OOM's before even getting off the ground in a like-for-like scenario.

I see that this utility has something called 'Virtual Memory Trim Automation'. Does anyone know what that does?

I have a question on this I find puzzling. If FSX for example is limited to approximately 4Gb of memory, how are some people plagued by this and others not? I've seen folks using worldwide detailed scenery and photo real texturing, yet I cannot complete a fourteen hour flight without the memory warning followed shortly after by the OOM, usually on approach. If this is an actual limitation of the software, how isn't every Flightbeam, FS dream team, REX, FS global, PMDG user not effected by this.

Todd, I'm as perplexed as you are on this one. I've been simming for 16 years and have literally never had any OOM issues until 2 months ago. It seems to happen when using a PMDG aircraft and addon sceneries , so lots of memory load there, but still, it doesn't explain the a complete change in my system now not being able to cope with it suddenly. This can only mean that something in my setup has changed which is causing this and I'll be damned if I know what it is. I have also tried subsequent fresh installs of 2.4 and 2.5 with the same result. I'm thinking about a fresh W7 install, but honestly I don't have the motivation to deal with that right now ...especially if I'm not sure it'll change anything.

I was reading yesterday on a forum about Chrome, that sometimes it uses large amounts of memory. Maybe when another program updates like a browser, this is what changes. One thing I like about this process lasso, is it shows you real time, how much memory is being used by each program that is running.

Memory as in RAM or memory as in VAS?

Wow, amazing how much attention this program is getting, not too dissimilar to FiberAccelerator, which came out not too long ago.  I went out and bit the bullet, purchased it to see if it would make a difference with FSX.  Turns out it really didn't work at all and $24 down the drain.  I DID however, find the cure for my FSX issues though and it's WELL worth it:  move to P3D.  :lol:

Just read an article from PMDG on OOMs and they attribute most of  the problem to add ons like photo real scenery as well as some of the graphics settings. I learned that lesson years ago with FS9 and FSX and decided that 10 FPS was not worth seeing photo real scenery of an area or airport. I never bought any of that when I switched to P3D, and I think that is the main reason I don't have any OOMs at all.

I recently  started to use  https://bitsum.com/processlasso/. Yesterday I made my  first  7 Hours flight with out OOM  with Bitsum Processor on. I also lowered  my FPS to magic number 20 . Also lower  some sliders  .

And that is what I read from several different people on facebook yesterday,  which Is why I posted a thread about this , this morning on this forum. hey if I had OOMs, and had tried all suggestions to no avail, I would certainly give this free program a try. It certainly can't make things worse.

Well, I will certainly give it a try and see what happens.  I'll report back.

There's no hidden magic behind managing VAS, but if you are not managing it then you will have problems. Just like a typical household budget, you only have so much to spend if debt is not allowed.

 

All photoreal scenery loads, used or not, so watch out for add on sceneries like Aerosoft and FlyTampa that like to add lots of photoreal scenery. I like them and use them but only get turned on when I am using them.  I have found that adjusting textures and most sliders has no measurable effect.  Water effects do hit. My clouds are DXT5 textures from REX Soft Clouds with HDR and look stunning and do not seem to hit VAS very hard but they do cost something out of the budget.

 

I use Process Explorer to manage my system, but also the FSUIPC logger display of remaining VAS on the Window bar is a must have for me.  My typical PMDG 777 flight will almost always have a save/load point where I set my aircraft to HDG and ALT modes and at least a few minutes before the next waypoint (usually 40 nm before TOD unless I have more than 1GB VAS remaining) I save the flight. Exit P3D. Restart P3D and load the saved flight. I will see typical VAS remaining numbers increase from 700MB to 1600MB and the rest of the flight is uneventful.  It takes longer to type what I do than it takes to actually do it. I choose to use my VAS budget on nice scenery, all the Orbx FTX stuff, lots or airports, nice PMDG airplanes and for this I have to do a save/load cycle. No big deal.

Dan, I've used the practice of saving and reloading flights for many years.  The issue I'm having lately is that the OOM is happening very quickly after the flight initially loads (on stand at EGLL in a PMDG aircraft) - sometimes with no AI.    I will try disabling addon airports in the area which I am not using (Gatwick, Stansted) and see what happens.

Ouch! Maybe there is one bgl file in one scenery folder that has gone bad. I think you are on right track, turn off sceneries until problem is solved.  Be sure you are using something like Process Explorer to measure your VAS loads (or even the FSUIPC logger).

Yes,

 

I have been very careful with VAS and overall settings in FS2004/FSX/P3D since day one and I finally reached some balance in P3D when I can fly no worrying about VAS (assuming constant saves before T/D), however PMDGT7 + EGLL combo (either UK2000 or Aerosoft) = OOM within 20 minutes after initial load. I checked for everything - doubld bgl, ADE, corrupted texture files. Nothing wrong. Seems like a bad area for PMDG T7. PMDG NGX or Aerosoft AB both work well. Those additional 400-600MB of extra VAS used (over NGX and AS AB) for T7 is the problem. 

Not blaming anyone as I understand the natural limitations.

I have paid version of FSUIPC but I see nothing in the menu about a VAS logger.  Where is it?

I have sat for 30 minutes with no changes in the scenery other than the clouds rolling by slowly and have noticed VAS just bleeding off bit by bit.    Surely if everything has loaded in the area and nothing new is being introduced to the area you would think the VAS would remain constant but it does in fact bleed, at least on my system.    It's a very slow bleed but it does bleed.   I typically land at my destination without having to save and reload anything though with AI on with about 500 megs left of memory which is enough to avoid hearing Dings from FSUIPC.    It would be nice of P3D would let things go more efficiently and would certainly be nice if the VAS wasn't bleeding for appears to be no reason I can see in the visual area.

lets face it PMDG we hope have learnt the VAS lesson for their coming 747.

 

would be a shame to see shiny new pmdg 747 that eats all VAS and leaves no room for addons.

 

Maybe its time to lower some of that pmdg complexity vas use to gain more room for addons, cause ill gladly give up my pmdg if it means I cant use other add-ons without oom

 

As has been mentioned multiple times the biggest vas culprit is PMDG products.

I wonder for how long this issue will be a discussion...

As long as there is someone frustrated enough with OOM's with enough bother to understand why it is happening, it will always be a discussion. My issue is not that I have OOM's. My issue is that they have appeared overnight, and I don't know why (well, I do know why, but not why I'm experiencing a sudden change). I have had a like for like setup for years, and OOM's have only recently started happening.

 

Sitting on the stand at Aerosoft's EGLL with the PMDG 777, REX clouds, Orbx Global, EZDOK and Track IR.....I have almost £350/$500 of software /hardware invested here.....that alone is worth the discussion.

 

 

Out of interest, has anyone disabled the external visual model for the 777? If so, has it made any difference?

See the PMDG 777 Introduction pp 29-30. You can use the Process Explorer for many tasks including setting the affinity mask for any running process. The FSUIPC tool is very handy in that it puts a number right in front of you all the time.

 

As far as blaming PMDG 777 goes.... the product uses about 800 MB of VAS. Period.  Nobody ######es about their beautiful scenery, it must always be the airplane because other airplanes don't have  this problem, so the argument goes.  PMDG is aware of this perception and has five pages in the B777 Introduction on the topic.  There was one problem identified early this year that took months of testing to isolate and fix. It's been fixed.  There's been plenty of finger pointing but so far no one has come forward with data to support their arguments like happened early this year. There was a group that banded together to prove there was another problem but they suddenly got quiet.

 

Anybody is welcome to present data supporting the argument that the PMDG 777 Product is the sole cause for OOM errors. I look forward to seeing something substantive.

I don't think anyone is 'blaming' the 777.  As a premium line product, i think it is generally accepted that the cost of VAS is high.

Dan,

 

Obviously it's not a cause, it's merely a BIGGEST contributor into equation.

 

Here is the situation...default UK2000, P3D and F22. No autogen, LOD 6.5, 1024 textures, REX with 512 clouds,  Turning FSUIPS VAS monitor ON and see...

 

1) VAS Remained (VAS-R) = 2.4GB

2) Adding UK2000 EGLL + 100% AI (FAIB, AIA, TFS, all textures are DDS with mips + manually validated) VAS-R = 1.9 GB

3) Adding UTX Europe 2.1 without autogen = 1.6GB

4) Now adding Aerosoft Airbus = 1.1 - 1.2GB ans stable

5) Exiting P3D, the same scenario as with steps 1-3m, but adding NGX instead and we have 900M-1GB of VAS left and it's stable.

6) Finally...exiting P3D again and loading T7+ FS2Crew. Now I have 550-600Mb left and after I made 3 or 4 head 360 degrees turns, VAS-R comes down to 350, then 250, then FSUIPS starts to alert and then...caboom, i.e. OOM.

Thus, 800GB of VAS usage in P3D environment it's about 50% of available VAS. And yes, T7 is the biggest VAS sucker literally. I don't know what you cook now with 747, but I'm afraid that I will abstain from purchase at least until I see positive reports ob VAS.
