4Gb patch.

[Ferry_vO]

I found this little tool while searching for ways to make my GTR2 racesim more stable on my Win7 64bit system, but I've applied it to FsX too and I seem to get a beter and more stable framerate with it.
If you try it, don't forget to backup your FsX.exe file first!

What it does is it enables old 32-bit executables which are limited to using 2Gb of RAM on a 64-bit system, to use 4Gb RAM.

Edit: Of course this might also work for Fs9, CFS2&3 etc. etc!

I tried to use it for FSX, but got the error message "couldn't open executable". I haven't run FSX today, so I see no reason why the executable could not be opened. Any pointer would be highly appreciated!

Maybe it's set to 'read only'?

Thanks for replying! ;)

Just checked, and no, sorry, it is not set to read only. In the security tab of the file properties I also made sure that I have full rights. I am admin of my machine and UAC is turned off. A bit baffled here.

I'm going to reboot and try to run it in safe mode.

I have another question though: does the patcher need to be in the same directory as the executable one would want to patch?

EDIT: I also gave myself full rights to the fsx folder. This is going to take some time! LOL!!!

No, I just ran it directly from the zip file, selected FsX.exe and that was all.

Got this link from another thread here.
I expect it's the same sort of creature...;)

If you have FSX SP2 or Acceleration, the 4GB switch is already "on".
Unless you have FSX v1 or SP1 only, any improvement will, I am afraid,
be imaginary.
Even with the two earlier versions, the only improvement would be a delay
in reaching the OOM error.
Sorry.

That about explains it Nick, I have Acceleration! Thanks for the clarification!

And I'm afraid it doesn't work on the CFS3.exe either.

What magic have you worked Ferry to make this thing patch?! :D
