Question regarding VAS and My Traffic Pro


Recommended Posts

  • 2 weeks later...

Virtual Address Space, Burkhard. It's running out of VAS that causes most crashes of FSX.

 

PMDG posted a good knowledge base article about it here: http://support.precisionmanuals.com/kb/a108/vas-management-stopping-out-of-memory-oom-errors.aspx

However, the answer to the OP is that it depends on how high he sets his sliders... if the VAS usage is too much, turn the AI down! ;)

Never had any problem with that, MyTraffic needs about 200MB of extra RAM compared to the normal 700 I see with FSX, so if you run into the 2.5GB limit you must have many addons that are far more demanding, and you are right, turning AI traffic slider down reduces the amount of memory FSX uses for AI traffic.

Actually, there is another option. There is a freeware app  (which of course runs in its own address space) that is commonly referred to as the FSX/P3d Traffic Optimizer, which can be found here:

FSX and P3D only set AI traffic levels as a percent  of the maximum that can occur within the user's "bubble". What the app does in addition, is that it also limits AI aircraft within the bubble to a user specified number like either 50 or 100, while preserving local traffic at the user's airports. This app substantially improves performance and also reduces sim VAS usage while still giving realistic amounts of AI Traffic. It works great with My Traffic Pro.

 

. if the VAS usage is too much, turn the AI down! ;)
