I know there are other posts about DirectX, but I haven't found one recently, and using the search bar for directx crashes.
Using a template from a bug report forum for BF3:
Issue: Crash to Desktop (CTD)
Platform: PC
Map: South China Sea
Mode: Campaign
Description: Right after fighting through to the doors of the med-bay after getting onto the Valkyrie I get a CTD with this message after trying to activate the door.
" DirectX Error:
DirectX function "GetDeviceRemovedReason" failed with DXGI_ERROR_DEVICE_HUNG ("The application's device failed due to badly formed commands sent by the application. This is a design-time issue that should be investigated and fixed."). GPU: "AMD Radeon HD 6900 series", Driver: 13.9 (13.152-230830a-163178C-ATI) "
Has happened twice now in the same spot. I will try and update my GFX drivers to the beta version and see if that helps.
As a side note, i've read on this forum from a helper/hero/com. manager that EA doesn't read these forum posts, yet here: http://battlelog.battlefield.com/bf3/forum/threadview/2955065670118762490/last/ it says to post in these forums for technical issues, which I kind of get, but how would EA know of the bugs/glitches/crashes or other random problems with a game if they don't read this forum while directing users to this forum for tech. issues? I find it kind of defeating the purpose if they'll never read the posts which would allow them to push a fix in a patch.
