When I first installed v2.5, RAM use seemed perfect and didnt think I'd ever get to see OOMs. Only since last week I got trouble when loading a second flight and P3D ran out of available memory, with just 3.4GB RAM in use at that moment.

This morning it got even worse. My first flight of the day, I just started up my pc and P3D, and like 5 minutes into the flight P3D ran out of available memory with no more then 2.2GB of RAM in use.

 

The only thing changed in my setup is the addition of the Realair Turbine Duke, to which I added the Mindstar GNS (which was already on my pc for other aircraft). So I deleted the Duke, to see if this would make any difference, but it didnt.

 

Could someone help me find the cause of this problem and get it fixed?

You need to monitor Virtual Address Space (VAS) instead of RAM. You can use the free Process Explorer, for example.

In Windows, what is your pagefile size?

I was actually having out of memory issues with X-Plane 64bit until I changed this value. I used 4096 as the pagefile size.

Paging file is automaticly managed and is set to 8130MB.

 

I'll have a look at process explorer and see what VAS is doing.

 

Thanks guys!
