Weird RAM/Memory obervations...

SOH-CM-2025
when I recently tried to reinstall my four DVD VFR Germany 1 photoscenery I ended up with a prompt that I ran out of Memory just at the end of DVD 4. I repeated this several times, still the same. I reduced the strain on my Memory, changed the settings of virtual memory to and fro. Still the same!!! Couldn´t install!

Then I recalled I enhanced my RAM-usage for Vista to use more system RAM which worked great. I put this back to default - less memory! And it worked again, moreover I seemed to notice an increase of speed/fps in FSX, too! Strange stuff!

BTW: throwing out the custom autogen from that scenery (leaving only the trees, Landmarks and airports as objects on the photomesh) really increased my fps. With a full install using the custom houses - even with low autogen density - the scenery was a framehog like no other!

Sometimes things don´t have to be logically based to work!

I´m tricky:icon_lol: The scenery ads new autogen descriptions into the autogen.xml file. I backed up the file and installed VFR1. I simply deacitvated the new changed file and replaced it with my backup version. The scenery now isn´t able to place any autogen buildings, cause the specific lines are missing!

Details?

I am having OOM problems also...Could you list your memory settings/details for me...I'm willing to try anything! Thanks...

To enhance the memory usage of your OS type the command line "cmd". A DOS window will open. Add the lines:
bcdedit /set IncreaseUserVa 3072
then press enter. Now your system is able to use 1 GB more RAM.

To return to default simply type:
bcdedit /deletevalue IncreaseUserVa
enter again.

I went back to use default system memory again, since the enhancement obviously changed my memory usage to the worst.

The UserVa setting changes the virtual address space available for programs. It has nothing to do with Ram memory.

So, is this setting worth trying or using? Thanks...

The short version........Yes...

But there is a reason for your problem as it was not happening before...

maybe you got a install that went funky...Like scenery, planes, or the like....
 
Basic Problem Solved

My basic OOM problem seems to be solved...Harlyman, your PM jogged something in the back of my dusty brain...I deleted the fsx.cfg file and let the program rebuild it...For some reason, that seems to have solved the problem...I am now just looking for ways to maximize the performance...So, I will try this setting and let you all know what happens...Any suggestions on maximizing RAM are still welcome!

Correct, I mixed that up a bit.

Since the settings started to turn out slowing my system down lately I will try different settings to find out what´s really best for my performance. Just strange it all went well and all of a sudden performance drops or produces malfunctions with this settings.
