Hey!

Issue seems to be fixed. Not sure what made the difference. Tried running windowed and joining a server without any issues, and afterwards going full-screen while in game without any problems.
Later clicked "Restore default settings" inside the Basic tab of the ArmA 3 Launcher. It seems to be working.

Sounds as if we have the same problem. My ticket:

Still not working in any way. Tried a lot of other games without any trouble what so ever. Validated the game files once more. Trying to opt in to the DEV-branch now to see if anything happens.

After switching back to 1.42 from the dev, I tried running the game in windowed mode. It seems to be working fine and has done so for >10 minutes now, but still the DirectX in the .rpt-file seems to assign the Intel 4600 instead of my GT 750m.

Windows, or rather nVidias own monitor, seems to think that the dedicated GPU is handling ArmA as well as the launcher.

Could really use some backup by now :)

Later clicked "Restore default settings" inside the Basic tab of the ArmA 3 Launcher. Will report back if another situation arises. Will notify other user as well about it working with this / these steps.

.rar-file contains error from dev-branch. It seems the bidmp and mdmp-files were created for this instance as well. Stayed in the lobby, and could press okay before ArmA crashed. This time, an error message from Windows about ArmA crashing was present as well.

Giving up for tonight. Really can't seem to get it running :(

Still not working. Forcing it to use the GT 750M in the user config file leaves me with ArmA running in the background, but with no way to bring it up.

Tried using only my laptops screen, as well as disabling the laptop screen and using external screen / screens.

I stumbled upon some information when reading the error reports (.rpt-files), since re-installing the game as well as installing GPU-drivers didn't do anything. Here it is:

22:36:15 DX11 - Initializing DX11 engine.
22:36:15 DX11 - Using DXGI adapter 0 (detected in config).

22:36:16 VRAM is too small (402653184), we need at least 536870912.

I'm 100 % sure ArmA is set to run with the dedicated GPU instead of the on-board, and the launcher is as well. I've checked with the nVidia control tools to see if it thinks ArmA is utilizing it, and it does. I'm very confused - tried running it manually as administrator and out of steam without any luck.

Now, I tried messing with the Arma CFG file in My Documents > ArmA 3 > arma.cfg

More specically, first I tried altering

detectedAdapterId=0;

to

detectedAdapterId=1;

Didn't help:
22:51:29 DX11 - Initializing DX11 engine.
22:51:29 DX11 - DXGI adapter 1 detected in config does not match current adapter with this ID.
22:51:29 DX11 - Detecting best GPU adapter.

And then I left it at 1, and tried altering

forcedAdapterId=-1;

to

forcedAdapterId=1;

And I got the following:

Both reports are uploaded.

In need of better ideas I've deleted the game, and am re-installing it right now. Will give it a go, and further re-install GPU drivers afterwards if the first has no effect. I'd really like to play :)

Hi Adam. Glad to see someone on the case :)

I may be reading/doing something wrong here, but I only have the .rpt-crash files in the specified folder. There aren't any bidmp or mdmp files as far as I can see.

Thank you.
