Mantle API - Compatible and Selectable?

Bump.

I have the Catalyst Version 14.11.2 Beta and it's supposed to enable mantle but I'm still stuck with Direct X 11. I have a AMD Radeon HD 6900 Series. Not sure what`s going on.

I had this issue as well. Had a supported card and the correct beta driver and everything! Solved it by doing the following (Instructions written for Windows 8.1 but should be easy enough to follow on 7):

Disable Windows automatic driver install.

1. Hit Windows-Pause/Break
2. Click "Advanced system settings" in the lefthand bar
3. Click the "Hardware" tab
4. Click "Device Installation Settings"
5. Click "No, let me choose what to do"
6. Click "Never install driver software from windows update"
7. Save changes

This prevents Windows from automatically installing an out of date GPU driver while you're trying to do the next two steps. You can put this setting back when you're done.

Uninstall all AMD Software

1. Open Control Panel -> Uninstall a program
2. Click "AMD Catalyst Install Manager", then "Change"
3. Choose the option "Express Uninstall All AMD Software"
4. Click through the uninstall

Doubly uninstall the graphics driver

1. Open device manager
2. Right click on your GPU device (it's under Display adaptors) and hit "Uninstall"
3. Check the box to delete the driver too

Delete any cached AMD driver installers

1. Open C:\AMD\ and just trash everything in there, particualrly folders with names like "WU-CCC2"
2. Reboot your PC once you've done this

Your PC will now have no GPU driver when it reboots and your resolution will likely be reset. This is normal.

Install AMD Catalyst 14.11.2 Beta Drivers

1. http://support.amd.com/en-us/kb-articles/Pages/AMDCatalyst14-11-2-BetaWINReleaseNotes.aspx
2. Not gonna step-by-step this one
3. Reboot again when done

Now when you launch Dragon Age, you SHOULD be able to select Mantle as your graphics API in the Display settings. You can put back the automatic driver install now.

What the last guy said, only you can simply just use DDU driver uninstaller/cleaner. Let it reboot your PC into safe mode to begin and finish the cleaning process. Then you can do the fresh install of the newest AMD drivers.

This does not work without DDU step. I have just finished all the other steps. (Uninstall all AMD programs.... reboot..... install catalyst 14.11.2...reboot....mantle isn't selectable in game.)
I'm going to try uninstalling, rebooting, DDU cleaning (via safe mode reboot), reinstalling and rebooting now.

I have AMD 7660 graphics.

I hadn't heard of DDU until just now, but what it does is almost identical to what I wrote above. The key steps are disabling Windows update from going and fetching the new driver automatically and manually uninstalling the driver in device manager, including deleting the files.

Using DDU should be way easier though.

Okay, mantle still doesn't work. Uninstalled catalyst... rebooted...opened DDU v13.5.1.3... rebooted into safe mode and ran it.... rebooted....installed catalyst 14.11.2...rebooted....ran Inquisition. It runs nicely with most settings on low, but I can't enable mantle. Here are my specs:

OS Name    Microsoft Windows 8.1

Processor    AMD A10-4600M APU with Radeon(tm) HD Graphics, 2300 Mhz, 4 Core(s), 4 Logical Processor(s)

BIOS Version/Date    Insyde F.12, 8/23/2012

Installed Physical Memory (RAM)    8.00 GB

Catalyst Version    14.11.2 Beta

Graphics Chipset    AMD Radeon HD 7660G

Mantle Driver Version    9.1.10.0045

As you can see, the cpu is below the minimum required. But 1: I can already run the game and 2: It appears that catalyst found my 7000 series graphics card compatible with mantle, and installed it. So what gives?

Mantle 1/2 performace

About the Benchmark in game I got med. 42 fps and mini 39 ( mantle)

In DX11 got 83fps and 79

All Ultra Full-HD

@Spitfireisland, nothing, all is good, cuz Mantle is supported only on GCN enabled GPU's like HD7000 series or newer..
