I'm beginning to suspect it's a video driver issue, I have just had the same type of crash when trying out another new game (star confllct).

I'm running the latest stable version of the catalyst drivers (13.1) but I will download the latest beta drivers (13.3) and report back.

No change running new beta drivers, crashes at the same place.

Game starts up runs fine for me. I get crashes/lock up requireing reboot like this only in vehicles. They seem to happen due too lag? Its only when I stop and start moving again quickly.

No, don't get as far as lag. I have yet to see the battlefield, except in map form on the loading screen. :-(

Do you have same problem in multiplayer?
Can you try start some mission from editor? Add soldier, some vehicle and try start it.
Do you have overclocked graphic card?
Did you try clean instalation of drivers?

Yes, exactly the same in multiplayer.

Tried starting an editor game, select editor from the main menu, then as soon as I click start (or continue, whatever the button to proceed is called on the editor map selection screen) I get the same crash, system lock etc.

Tried a re-installation of the game and latest beta drivers, same result.

Oh, and no, gfx card not overclocked, just factory clock settings.

Can you try it without eyefinity? Have only one monitor connected and try in native resolution of your connected monitor.
Crash dumps were not created and in log file is nothing usable for us, so we need locate where is problem.
Thank you.

Tried on a single screen with the other two physically disconnected, and I could run the game! My word it looks pretty!

So it looks like an eyefinity issue... any suggestions?

Got the same crash on exit though, after suspending the game and back to the main menu, select exit and PC lccks up, requires re-boot.

We tested and eyefinity worked correctly. This issue is maybe combination of eyefinity and some other software. We will try eyefinity again for sure.

Just FYI, I'm using 3 22" screens arranged in portrait mode to give a desktop res of 3150x1680. 2 of the screens are DVI, 1 is displayport.

Just tried running this again, there's been no changes, I still get the same crash.

Is there anything I can do to help sort this out? Some sort of debugging mode I can run the client in?

Mass closing ancient tickets with no activity this year; assume fixed or too trivial etc.

If this issue is still relevant in current dev build, please create a new ticket referencing this one and request for it to be re-opened.
