Man, for starters, backup/delete your fsx.cfg and let FSX recreate a new one. You have virtually every tweak I have ever heard of. Besides you have more than one Nvidia lines in your cfg.Also I would try disabling shader3 (uninstall it), delete shaders in the folder C:Users*Username*AppDataLocalMicrosoftFSXShaders to let FSX rebuild them.Don't start tweaking the fsx.cfg.Then make your settings only with your FSX sliders. Be realistic about your system and make normal settings, so that you get realistic performance.Also disable those sceneries Julian said.You should be monitoring your VAS with the process explorer (see here http://forum.avsim.net/topic/353179-gd3dllhelp/page__view__findpost__p__2161913)The question is simple: why is your FSX kicking so high when you are landing. The best thing is to start fresh and not working with the crazily tweaked fsx.cfg. With the CPU and machine you are having, you should need only very few tweaks. I get shivers when I look at the fsx.cfg like yours, sorry...

KostaWithout the Bojote's tweak my fps would been in the mid teens to low twenties, I'm not claiming to be any expert but it makes it hard for me to want to go back to my original .cfg.

Just to add another comment to the above, and this is only my observation, I found the US Cities KSFO a total waste of money unless you fly very low in the M$ Trike, and not for using any payware planes like the PMDG NGX or MD11 as an example. either of these planes will increase your chances of never making past the pre flight checklist.Even if you do manage to make it to your destination airprt, you will OOM as soon as the airport loads, as your VAS was near exausted at KSFO,and does not refresh that memory depletion just because you have left the terminal area at KSFO. Even worse if you fly from KSFO to KLAS.The eye candy is nice, but you have to decide what is important, be OOM free, or fly the M$ trike, I know what I would choose. :)cheers

I will disable those to sceneries and get back with you on my results.

The thing is: you can't go about tweaking the way you are tweaking without understanding it!I'm sorry, I can't port over my knowledge to you in couple of sentances.But I can tell you there are enough posts around here to give you some basic ideas. You just gotta go step by step, using search button a lot!

Hi Bank 1,I'm right there with you when it comes to this OOM thing. I have spent over the years tens of thousands of dollars on getting the right hardware to run this dinosaur of a game and only just recently I threw away my overclocked 990X for the super cheap SB. Thanks to some threads here on this Avsim site I made the leap backwards, so it would seem to the 2600k which remarkable has brought FSX almost to its knees. With a few minor tweaks like bufferpools, I am now enjoying FSX for the first time ever at its maximum potential. For the first time ever I have FPS over 25 flying the NGX/MD11 into any Dreamteam scenery with most of the slides max out however like you at about "cleared to land" time I get the OOM. I somewhat expect it to be a case of just being too greedy, because I'm running the slides pretty much maxed out now just because I can. I thought I was doing the right thing using W7 64bit, but when I get to 53% of my 12Gs of ram… up comes the dreaded OOM. I’m hoping some help is around the corner for us without having to tame down the slides and loose the candy. BTW I have tried all the pagefile options but for me this did not help. Thanks for your post DW

I can't believe the settings you have for traffic:[TrafficManager]AirlineDensity=20GADensity=20FreewayDensity=20ShipsAndFerriesDensity=40LeisureBoatsDensity=40That alone is enough to bring down a super computer! Way too high.Best regards,Jim

KostaAs I mentioned in post #7 I followed NickN guide & Win7 Opt guide to get optimized, but even with that my fsp where low not much better then my Q6600 @ 3.3Ghz. So when I installed Bojote's tweaks, man, I saw my fps increase from the low twenties to thirtys using PMDG 737NGX, MD-11& all FSDT scenery. Also when I don't understand something that's why I use the forums so I can get the knowledge to better understand what and why I'm doing something.Oh yeah, I still don't now what.... VAS???

Word Not Allowed can explain this a lot better than me, but until he gets to answer that for you,http://en.wikipedia.org/wiki/Virtual_address_spaceI have a GTX580 1.5GB and even with that I can get a OOM. once FSX uses up the alocated 4GB, an OOM will occur. The video memory is included in that 4GB allocation. As I said, Word Not Allowed will explain it better.

VAS, as Julian wikied it, is an address space application is really using. It's not measuarable with task manager. It's very important in troubleshooting OOMs and crashes, and plays a big role in tweaking.It's only measurable with Process Explorer from Sysinternals. There might be other programs showing it, but this one is easy to use.It's the one memory where you'll see mentions of 4GB max usage for FSX under 64bit OS. If VAS goes over 4GB, you'll OOM 100%.Some sceneries (eg. ORBX, Aerosoft sceneries...) are causing g3d.dll (see a huge thread) errors with a very high VAS usage - which is caused by addons like NGX. All them alone are usually not going to cause OOMs, but load enough into FSX, and you are going to start seeing problems.Don't get stranded watching the FPS counter. If you are pushing higher FPS, you are bound to start seeing problems at one point. This is why I recommend to anyone going that way to understand tweaks really and test them thoroughly - let me just say this, it's not enough just putting the tweak in and just go flying.Driver versions might also cause instability with one tweak or another.That is why it's almost a neverending story...When you start pushing for the higher FPS, it's a tradeoff for scenery and texture loading or telling FSX engine to omit some programmed safeguards (like Bufferpools for instance). Finding stability between high performance and decent texture loading is quite hard task. So you either go that way, takes a lot of time, or you simply remove some tweaks, lower some settings like traffic mentioned above, and it will perform well.As I see you are expecting FSX to perform too good with too high settings.

I can't believe the settings you have for traffic:[TrafficManager]AirlineDensity=20GADensity=20FreewayDensity=20ShipsAndFerriesDensity=40LeisureBoatsDensity=40That alone is enough to bring down a super computer! Way too high.Best regards,Jim

I sure missed that. Good catch!

See, I knew you would explain it better

VAS, as Julian wikied it, is an address space application is really using. It's not measuarable with task manager. It's very important in troubleshooting OOMs and crashes, and plays a big role in tweaking.

FSX can only "write" to the VAS table in 1MB contiguous blocks. If there are none available at any given moment, you get a big bOOM...

Jim I'm sorry my current setting are below, I've been using Bojote's tweak. Those setting had been changed awhile now :

Good! Just wanted to be sure. Glad to see your fps increased. A lot of people have had problems with Bojote's tweaks. They are not the holy grail fix for an old program like FSX so be careful. At least, if you get unexplained crashes, you'll know where to look first! I have only one at the current time - the highmemfix=1 and I know for a fact it works great as I had ghost cockpits/aircraft when hitting alt-enter w/o it. You have a very nice computer system that should perform well w/o any tweaks.Best regards,Jim
