Adamk99 Posted August 27, 2018 Share Posted August 27, 2018 Hello! I am having difficulty with Out Of Memory errors, but only at Heathrow. No matter what I do I can never get off the ground without an OOM; sometimes just changing views in the cockpit is enough to tip the sim over the edge. This problem is unique to Heathrow for me; all other large airports (e.g. LAX and JFK by FSDT, CDG, VHHH and MCO by T2G, MIA by LVFR etc) cope well with any aircraft, including the PMDG 747 with fairly high settings. With the settings turned down even lower, Heathrow OOMs where other sceneries perform very well. I have tried turning down settings, turning off people and buses in central London in the ORBX England contoller, I have tried never leaving the flight deck (other large airports I can change view often without issue) and have even ran both the Aerosoft and UK2000 versions seperately (I uninstalled one before trying the other so that only one was in my library at a time) and had the same problems each time). I have even turned off other London sceneries while using LHR, as well as all photo sceneries. LHR used to work fine for me which makes me suspect a double install causing problems but I am really unsure. Any help would be gratefully received. :) -Adam Link to comment Share on other sites More sharing options...
pvarn Posted August 27, 2018 Share Posted August 27, 2018 Need more info: System and graphics specs. List of add-ons including scenery, aircraft, weather, DX, etc. -Pv- 2 carrot salad, 10.41 liter bucket, electric doorbell, 17 inch fan, 12X14, 85 Dbm Link to comment Share on other sites More sharing options...
CRJ_simpilot Posted August 28, 2018 Share Posted August 28, 2018 Read my Sig. OOM errors? Read this. What the squawk? An awesome weather website with oodles of Info. and options. Wile E. Coyote would be impressed. Link to comment Share on other sites More sharing options...

Adamk99 Posted August 28, 2018 Author Share Posted August 28, 2018 Hi guys, Thanks for all the above suggestions. I'm currently away from home but I'll have a look when I get home. In regards to more details, I run FSX:SE with a GTX 950 graphics card, an SSD I can't remember (it's middle of the road, nothing fancy but it copes with very large airports with ease, with the exception of LHR and, as a Brit, I'd like to be able to fly out of it :) ). Addon wise, I have the FSLABS A320 and PMDG 737, 747 and 777 installed alongside the defaults, copious addon airports (most are switched off) and ORBX base and N. America LC, ORBX England, Scotland and Australia. Some photoreal is also installed but remains switched off when not in use. I also run Active Sky Next and have extra weather textures by REX, but these run perfectly well in all scenarios bar at LHR. Thanks, Adam Link to comment Share on other sites More sharing options...
pvarn Posted August 28, 2018 Share Posted August 28, 2018 AS16 uses memory better and is in every way far superior to ASN including starting and shutting down instantly. We still don't know your installed system RAM or OS. Your GTX 950 2G mem should be fine. Try switching off your LHR add-on and see if the default runway does the same thing. As mentioned, look carefully for duplicates in anything including AI routes. -Pv- 2 carrot salad, 10.41 liter bucket, electric doorbell, 17 inch fan, 12X14, 85 Dbm Link to comment Share on other sites More sharing options...
Adamk99 Posted August 28, 2018 Author Share Posted August 28, 2018 My OS is Windows 7 (switched from 10 due to problems with installing certain addons) and I have 8GB of RAM installed. Thanks for the advice r.e. AS16, I'll have to have a look into it. I'll also try LHR default when I am home, I hadn't thought of that.

jorgen.s.andersen Posted August 28, 2018 Share Posted August 28, 2018 Have you tried the tweaking tips you find here: https://www.flightsim.com/vbfs/showthread.php?259352-FSX-P3D-Software-and-Hardware-Tweaking-Guide? Especially HIGHMEMFIX=1 Also, we don't know what version of FSX you have - Acceleration or? Jorgen Link to comment Share on other sites More sharing options...
pvarn Posted August 28, 2018 Share Posted August 28, 2018 In terms of memory and performance, the two FSX versions are identical. I swap back and forth between the two daily and sometimes several times a day and monitor memory usage under the same conditions and scenery. My frame rates and memory usage are identical. Himemfix is absolutely necessary but question whether it's the sole contributor to one airfield. -Pv- 2 carrot salad, 10.41 liter bucket, electric doorbell, 17 inch fan, 12X14, 85 Dbm Link to comment Share on other sites More sharing options...
Adamk99 Posted August 28, 2018 Author Share Posted August 28, 2018 I use FSX:SE. I haven't done any tweaking before as up until recently I had no issues, but I'll definitely give it a go along side all the other pointers once I get home in a few days and I'll update on how it goes! Thanks guys! -Adam Link to comment Share on other sites More sharing options...
pvarn Posted August 28, 2018 Share Posted August 28, 2018 FSX-SE is functionally identical to MS boxed Acceleration/Gold in terms of how scenery is used and scenery compatibility. -Pv- 2 carrot salad, 10.41 liter bucket, electric doorbell, 17 inch fan, 12X14, 85 Dbm Link to comment Share on other sites More sharing options...
