OOM...advice please


Recommended Posts

So OOM's have not really been an issue for me. I am thinking it is maybe due to the more systems work being done with Aerosofts A320.

Flew from Gatwick to Manchester. ASN for weather..ORBX Global,Vector,LC europe and FRX England. P3Dv2.5...no trackir as that was jumping all over the place on friday.

All was fine with fps between 15-25 and remaining vas was between 600-800mb.

However as I park at the gate in Manchester I get an OOM warning on the screen...click ok and the sim shuts down.

So I made some adjustments a restarted the sim at Manchester checking vas remaining at approx 700mb.

So now the questions... I have read that ORBX Vector may be a cause of OOM..this is from Aerosoft forum ..others aay its too many apps open...I am guessing it is to do with the more going on with the A320 and a busy airport like Manchester as I have no issues with all my GA..even A2A I still have over 1gb vas reamining.

I currently have 2 x 4gb 1600 speed corsair vengance ram.. is it worth having 2 x 8gb sticks of faster ram instead?

My card is a GTX970 at 4gb.

My cpu is i53750 at 3.0

I have turned some settings down and will try some more flights..I ran a low level test flight last night with AP on at 5000ft with ASN weather..all seemed ok.

Ai traffic is set to 10%.

I only have shadows within my Aircraft and caused by my Aircraft.

My next purchase is the Dash 8 from Majestic but I am concerned it my cause OOM. What is the difference with the Dash running thing outside of the sim..does that mean it wont use so mush of the resources within the sim....

Like I said I dont get these issues with GA and nothing has changed aside from getting the bus.

My cpu was never at more than 85%.

Thanks for any advice.

OOMs can be hard to pin down the exact reason for, but in my experience flying any where near London is a good way to cause it. With ORBX England installed I have to take my settings way down if I'm going close to the London area...

 

The Airbus surely will eat up some extra memory compared to any GA as well, but my guess is that it's the scenery that's causing it.

 

You say you are using ASN for weather, but no mention of add on weather textures. If you use REX Textures I'd opt for using 1028 resolution coulds rather than the full 4096 resolution. That will save you a bunch of memory on a cloudy day.

 

Increasing the available memory as you suggest won't do a thing to avoid OOM as FSX/P3D can't use more than just under 4 gb (including the VRAM on your graphics board) anyway. So unless you are running a whole bunch of other programs at the same time there's no benefit.

Thanks Mikael, I have put the REX textures down and have played around with some P3D settings. I did 2 test flights, one with the Airbus and one with a GA from Carenado. The vas was about 600-800mb more for the bus, and according to Aerosoft that is what you should expect. I was about 500mb less useage than when I had yesterdays OOM, so I think your tip may have sorted it, also I guess in the A320 I dont really need such a high level of ground detail.

It would be good to hear from anyone not using ORBX Vector and see how they are finding it.

I'm running ORBX vectors, and have seen no increase in OOM-issues after installing it.

Over the UK it won't matter for me though since I have all their full-fledged regions as well, and with the region set to Global in "Hybrid mode" the region will have priority over the Global stuff..

Hi, Wayne.

Please forgive the brevity of this reply, but I have said all this before both here and elsewhere, and it has indeed all been said before by many others, so please feel free to Google or whatever to fill in the gaps. :)

To summarise, then: OOMs occur when you run out of VAS, typically at the end of a long flight into a complex airport, especially when flying complex aircraft. Unless you have comparatively little RAM, adding more won't really help, (though reducing the complexity should. But...).

The solution that worked for me was to install Steve's Fixer and shift permanently to DX10 mode. For more information, see http://www.mutleyshangar.com/reviews/bc/dx10/dx10.htm

This works because in DX10 the GPU takes over various graphical functions from the CPU, so there is more VAS memory available for FSX. Other suggestions abound, but for FSX this is your bet bet, (IMHO). However, you would certainly need to get involved with the technical stuff, as you'll see if you read the review in the link above.

There is also a suggestion that in P3D version 3, VAS usage has been reduced (allegedly - i.e. I haven't tried it myself, so I can only pass on the suggestion. Others here can give you information about it, though). I'm not sure which flight sim you are running, hence the double recommendation.

But I do think that one of those two approaches is your best bet. Faffing around with sliders and "tweaks" has been known to drive people nuts....

(Just my two cents...). ;)

Good luck!

Cheers,

Hi Brian

I personnally dont see any difference in the 2 p3d versions..there is a little but its nothing to write home about.

I have removed my Traffic 360 as I dont really use that much... I watched a video by Fooogle where he said about a program he used that puts parked AC at airports.

I am guessing that I got the OOM as I am using the Airbus and more resources are being taken.

I try not to tweak to much but have fone down the route of aeeing if there are things I have added that I dont need.

I did note that my GPU is never really worked hard by the sim.

I was jyst so pleased that I finely nailed a good landing but then it OOMed when I parked.

Cheers

Hi Wayne,

Plain and simple, it's Orbx England. If I fly with Orbx England installed, I'm almost certain to get a OOM. It's just awful. I don't know why, but the Orbx uk stuff is horrendous on VAS. Try uninstalling it and rerun the flight.

As for p3d v3, I can confirm that vas handling is miles ahead of 2.5.

> "I was jyst so pleased that I finely nailed a good landing but then it OOMed when I parked"

<sigh> Yeah, that's what really hurts. It always bites you at the end of the trip, just as you're thinking that all is well.

We all have to find the best accommodation that suits our own preferred sim / way of flying / choice of aircraft / type of scenery and so on, so there isn't a "one size fits all" solution, sadly.

Hence the expression (usually uttered through gritted teeth when we're in the middle of struggling with the technicalities) - "I'd rather be flying!!". ;)

Cheers,

bruce

I am lucky so far with out of memory issues. My computer chimes when it is getting close to running out of memory. If I am very very near the end of the flight I often have time to land. But if I am still a little ways out, I just saved the flight, close the sim, reopen and restart from that position... Usually no problem for the rest of the flight.
