Dear Simmers,

As we get more and more plagued by OOMs in FSX due to 4GB constraint, there is a Microsoft fix that apparently helps to prevent an OOM happening in both P3D and FSX.

Beware that this is not a FIX to prevent OOMs altogether, it only helps a bit. FSX/P3D will finally crash if you keep on using the sim.

Until now there are no adverse effects on using this “fix”.

Link to Microsoft fix.

Just download and install the “FixIt”.

It will change the heap limit.

The default being:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\SubSystems

SharedSection=1024,20480,768

and the FixIt is going to change the 768 to 1024.

Here is a screenshot also showing where this is exactly located:

This is only for x64 version of Windows 7.

My thanks go to OmniAtlas for posting this!
