Lockup with Crossfire?
 

New beta patch has great colour, great sound, the mg's could be a little louder...

BUT

I get regular and constant freezes (have to force-quit), or sonic assault-type lockups which force a reboot. The dump errors usually involve an ATI module.

My frame rates have also dropped a touch, though the game seems smoother overall.

The game was formerly very stable on the previous patch.

I have:

WIN 7 Pro 64 bit
8 GB GSKill RAM
AMD Phenom II 3.4 BE
2 x 5830 Crossfire

The gunner position dont shoot with the left mouse button (default)
also the mouse movements are fault , when you move mouse up de gun go down , when you move mouse down the gun go up

Downloaded from megaupload. The game doesn't start anymore, or better, it apper the target aim on blak screen, and nothing else happens for almost a minut, then the target disappears and the screer remain black. Aborted through task manager, reboot, launched again.. same outcome.
I tried the copy from Torrent but it didn't fix nothing.
I'm going to do a roll back, to the previous windows savepoint, hope this will let me to get back 1.3 version.

My PC: Intel sandy bridge 2700K, MB ASUS, Nvidia 580GRTX, 8 GB corsair 1600 Mhz, 2 x 120 GB Corsair HD Solid state, 2 x 520 GB WD, Logitec G15.


PS, it didn't works, my copy of CoD os definitely ruined, I'm afraid I'll have to download it again from steam... :-(

You can make Steam check all the files and revert to the last official patch.
Open steam and rightclick CLOD in your gameslist, choose "properties" and then "local files"/"verify integrity of game cache".
It will check all your files and replace the new ones after which you'll be back at the last official patch

Thanks for tip, Warhound. It works, CoD is back now. This Steam... not bad :)
