AMD Needs Your Help: Catalyst Driver Special Submission Form

[gareth170]

I'm downloading the 14.7 RC3 drivers Gareth and will test it myself and report back shortly.

I've reinstalled the game and enabled both options and it seems to working now

why does crossfire work under Mantle in Thief perfectly with just 'full screen' mode enabled?

Good to hear, It was working correctly for me as well when i just tested it.

One of the great and unknown things about Mantle is that crossfire mode can work in windowed and borderless mode. (called full screen mode in Thief) However this is not currently supported in crossfire when using DirectX. For crossfire to work you must use full screen mode and exclusive full screen mode. I expect you had one of those unticked.

Under Mantle, crossfire in windowed/borderless mode will work to about 65-90% of its full capacity per gpu. This largely depends on the resolution used. Running it in windowed/borderless mode does add some cpu overhead which lowers performance and scaling a bit.

Glad it's sorted now, enjoy.

Just wanted to say well done, Matt. You should be very proud of yourself.

Right this is drivging me up the wall. Since going 4K I get this error everytime I try to join a BF4 game. Only way to join game is to delete my profile in The BF4 settings folder.

If I dont I get this error

Mantle function "grWsiWinTakeFullscreenOwnership" failed with GR_ERROR_UNKNOWN. GPU: "AMD Radeon HD 7900 Series" (26523), Driver: 83886080
