Graphics card not supported?

yeah no luck.

 

try to run a single card and insert the card to another PCI-e slot

 

Could be a Windows f**k up, I see a lot of games failing randomly because the OS install is screwed up. I have a friend who's PB fails on BFBC2 no matter what ... and I stipulate that it could be something in Windows that's screwing it up since her settings and my settings are the same. We only differ on hardware but that shouldn't affect pb.

@ElysianArcane - I seem to remember japamd's RadeonPro having an option to fake the vendor/device IDs of other graphics card so you could try that to see if it's a workaround for your issue. You could try the HD6970 or even an NVIDIA card. At least then you'd be able to play it until you can find a more permanent and proper fix for the problem.

 

Maybe you recently upgraded your video card, and not removed the old one entirely. Your game may see the old one.
If it is so, try this:

1. Open a Command Prompt and type:
Set devmgr_show_nonpresent_devices=1 press Enter

Devmgmt.msc press Enter

In the Device Manager window that opens, go to the View menu and select 'Show Hidden Devices'
If the old card is stil there uninstall it

 

Another thing it could be is if you flashed your GFX Cards BIOS. I have a 6950 with unlocked Shaders, stock Voltage, and stock Clocks. A few games I load tell me that I have an unsupported video card, than say it is a 6900 Series. But I do not have any options greyed out when I tell it to run anyway.

 

I noticed on the console that the game doesn't run a custom render path for my 4890.
Maybe it doesn't have custom render profiles for ATi/AMD cards as you know who had
some say & play during Crysis2 development... yup none other than nVidia
