The memory leak has always been in FSX, but with the performance
improvements in SP1 & SP2, you can increase the scenery density
and have a greater chance of having the out of memory issue.
Road traffic is the biggest offender. As vehicles appear on the
screen they obviously use memory, but that memory is not
released quickly on their disappearance. Very dense autogen
also tends to stay after out of view. If you want to try it, fly
the Lear at about 2000' AGL at 250 Kts over a densly populated
area following an interstate for about a half hour, len land at a major
airport and use F12 for the top down view and zoom out. For example:
With everything maxed, take off from NY, La Guardia in the Lear,
fly out to the end of Long Island at 2000' AGL, while staying over
the most dense autogen and road traffic, at 250 kts. Do a 180, fly
back to KLGA, land, and press F12 and zoom far out, then back in.
What happens is you're collecting objects in memory faster than
FSX releases them, until you run out of available memory. The
top down view is the final straw.
Even with 3 or 4 GB of RAM this can happen because only 2 GB
of virtual addressing space is available for applications, and FSX
isn't the only user of this space. Usually occurs when fsx.exe
exceeds 1.7 GB.
