Win 7 64 not working with arma2

[CtGuy]

I had been playing Arma 2 on Vista 32 bit and everything was fine. Now I formatted all my hard drives and installed Win 7 64 bit. No matter if I load Arma 2 in any mode (xp/vista compatibility) or if I turn off or on the PhysX mode, or anything, My graphics are really messed up, where I cant play the game. Ive downloaded all the newest drivers and cant figure out what to do.

Game people have weird heads that look half made, hands that look like the creature from the black lagoon, and those are in the videos, actual game play you cant make anything out.

Here are my puter stats:

Motherboard: ASUS P6T DELUXE V2

Memory: 12 gigs of Corsair CM3X2G1600C9 2GB DIMM DDR3 PC3-12800U DDR3-1600

Thanks for any help, Ive tried everything and have re-installed it as original version and then each upgrade all the way to 104 and no changes.

I had a similar problem with one gpu and 8gb ram, occourding to others apparently its too much ram. BUT when I take the ram out i still have this issue in seven and when I put in my decond crossfire card (HD4890) it goes away. BUT I still get crap performance. so I made the switch to xp and got the worst graphics corruption ever! I even run my windows 64bit with four gigs ram and the game is JUST playable. I think vista ran it better. I have tried all the shortcut switches and nothing works.

don't know about all the graphical wierdness you report but 191.07 works great for my single gtx280, i7 processor. one thing - when i went from vista 64 to windows 7 64, i was getting microstutters evey few seconds that did not exist in vista. the solution for me was cpucount=4 in shortcut target. took me hours to figure this out. runs FAR superior for me now than vista 64 ever did. might also want to doublecheck your graphics driver. i was so used to selecting vista 64 as my operating system that i downloaded the wrong driver for win 7. hope this helps.

add -winxp to the startup shortcut target

CFX+ win7x64+ beta = no issues really. Runs great. oh 6gb of RAM.

I have a i7 920 on win7 64 and diverent problems with arma2 (stutter,CTD,etc)
But with the last beta Patch and diverse parameters, my arma works better.
Not perfect but better

use beta patch : http://www.arma2.com/beta-patch.php
use arma launcher for simpler use: http://arma2.ar.funpic.de/


Launcher options:

-start the beta with the laucher
-set cpu count to 4
-use winXP mode

Id like to thank everyone for trying to help. Tim Rice....wouldnt running that just be a shortcut to going into compatibility mode and saying "run in xp mode"? I thought in my orig statement I said ive tried everything........but thanks anyway. Its just so unplayable its disgusting. I was able to get to the start of the game before, now it just crashes and I get a screen that says:

I finished the game MW2, I finished OFDR, and now I was going back to finish Arma 2 and I cant even play it. BENSDALE... I may try the patch, but Im not crazy about betas. Thanks for the help so far..............not working.

Not exactly. Running in XP compatibility mode runs in full XP comp mode, but running Arma2 with -winxp forces Arma 2 to use the XP version of direct x 9 as oppose to the Vista version (I believe running in XP mode in Vista/7 still uses the vista versio of DX9, it just disables DX10 features from being allowed)

install the latest beta-patch. launch the game using the "Launch Arma2 beta patch" shourtcut inside arma2 directory.
