    If you recently joined the forums you were not presented with this restriction in the terms of service. This was due to a conversion error when we went from vBulletin to Xenforo. We have updated our terms of service to reflect these corrections.

DEP Optimized?

Does anyone know what Data Execution Prevention is and how it can be accessed to ensure the settings are correct? I have been plagued with memory issues in 2.1 and it was suggested that perhaps P3D was not Data Execution Prevention-Optimized. I have never heard of it and have no clue how to check it.
 
lol, apparently I'm not the only one that's never heard of it, lol. 25+ views and no answer, lol.
 
Ed, DEP is a software security feature of Win7/8 that can prevent applications from executing or accessing memory allocations, you can change it easily like that:

Quite frankly, I never touched that because I never had memory issues. My newest scenery work, an island, has 9 phototiles, of which each hase a bmp size of 1.2 Gigabytes (!!!) and the sim swallows them without an error despite a hefty memory usage visible in the resource monitor. Sometimes I wonder where these memory issues come from.
I must say that I still have a relatively clean install, no ORBX stuff and so on.

If you think the problems can be adressed by configuring the DEP, I'd just add the P3D executable to the DEP exclusions and try it. Can't do much wrong here.

By the way, if there is really an issue with that then it could be a legacy problem, because FS9 / FSX also had these issues on some systems.
