------------------------------------------
Windows 7/Windows Vista
* In Windows 7/Vista go to Start menu. Go to Accessories. Locate the command prompt shortcut and hover mouse over it. Right Click on the shortcut then select Run as Administrator.
* In the command prompt type this exactly:

bcdedit /set increaseuserva 2500

Then hit enter.
* Make sure you get a message back confirming the change was made. To verify the entry is there you can type just bcdedit, hit enter, and you should see the entry now listed.
* Then close the command prompt. You just told Vista to increase user virtual address (userva) space to 2500MB.
* Changes take effect on reboot.
Now reboot the PC because Windows needs to set the userva at 2500 which only happens after startup.

If you skip any step it will not work. When you have rebooted you should be good to go. Run the game as normal with the original game shortcut.

TO UNDO THE CHANGES
Open command prompt as administrator and type: bcdedit /deletevalue increaseuserva. That deletes the entry.
Reboot and you are back to normal.

Can anyone tell me if this does indeed fix the crash to black screen with just the arrow available at map change for BF3? I am so sick of having to ctrl-alt-delete out at map change because the game gets stuck on some never ending black screen with just the arrow. If this does actually eliminate that problem, then let me know and I will apply the fix that Sheepdawg posted.

Thanks

im not sure if it will fix that issue, however at the bottom is the command to return to default values.  

Cant hurt to try.  It didn't completely fix my game, but now the only issue i have is the internet connection/ping to some servers.
