FSX running out of memory

[Martin Racette]

Hi,

I got the game earlier this week, and it runs fine except for the above
mentioned problem, I don't understand since my computer has 4Gb of RAM, and
all RAM meters never goes over 50% of the RAM that is been use

CPU Athlon 5200+
RAM 4Gb
OS Vista x64
Video EVGA 8800GTS 640Mb

What do you have setup for a pagefile ? I found under Vista, that it seems
to like it's meaty pagefile. Under XP, I often run with no pagefile or maybe
a pagefile around 512MB, since I have 2GB of ram. But under Vista, after
playing BF2142 for an hour or so I'll get a crash to desktop with a low
Virtual memory error. Once I upped the pagefile to 1024, that fixed the
crash in Vista.

Maybe you're problem is that you have too much memory, time to scale back
to1GB

The pagefile is managed by the system and is around 2048Mb

I tried your idea. and find it isn't the answer for FSX. My setup is
similar to the original poster. Vista Ultimate 64 bit, 4 GB RAM and an
Nvidia 8800GTX. I can pretty much cause the problem to occur simply by
flying over a city with the scenery and autogen settings at maximum.
After a few minutes all I have to do is switch to spot plane view and
pan around fairly rapidly for a bit. FSX goes into a bit of a coma the
useage for both cores on the CPU goes to 100% and FSX either crashes to
the desktop or produces the out of memory error. When it happens, I am
only using about half the RAM.

Well, if it's easy to reproduce, then it's probably just a memory bug, maybe
some kind of memory leak internal to the game in which a certain buffer or
register leaks out, but doesn't consume more ram. Maybe it's actually Video
ram that it's complaining about. Since the nVidia drivers are a little soft
right now, maybe it's the way they are doing something.

The game STALKER has kind of the same effect. Crank that bad bo up to Max
detail and full dynamic lighting and my X1900XTX will pause for 2-4 secs
when doing certain pan around looks. Though part of the problem is it
appears to be a poorly optimized game or it was written to run on hardware
that doesn't exists, they actually mention using a 8800TX or ATI 2800 for
max settings.

I'm curious, does you errr look like this

[error]Expression : fatal error
[error]Function : _out_of_memory
[error]File : D:xray-svnxrCorexrDebugNew.cpp
[error]Line : 339
[error]Description : <no expression>
[error]Arguments : Out of memory. Memory request: 4096 K

If so, there is a thread over in the Nvdia nZone about 7900 and above cards
getting out of memory errors, mostly in Vista

I will have to look more closely at the message the next time it occurs.
It occurred to me that the problem might be related to the graphics
card or drivers, because in full screen mode, the mouse cursor would
change from white to black before the crash.

Could it be a heat problem? Do you have any stability problems after
rebooting?

[Martin Racette]

I have no instability what so ever, my system is rock solid since I
installed Vista

This is really weird, i have probably the same system as yourself.. 4GB RAM but 2X 8800GTX Graphic cards SLI.. 64BIT Windows Vista.. this is a really powerful system, but yet the same problem as yourself where FSX seems to crash and says Low Memory... etc... i only have the right sliders on settings to half way, but all the left sliders to max..
I also have downloaded the latest up to date NVIDIA graphic drivers, so im slightly baffled, but glad to see im not the only one out there with a similar spec, where FSX is having problems running and where the same issue arises.. help!!
