Problems with AMD-Mantle

#1 I have a similar problem, but in general the message is regarding queue.

The BF4 starts up, then its screen goes white and when you alt-tab you get a popup similar to this:

Mantle function "grQueueSubmit(queue,1,&m_cmdBuffer,m_memoryRefSet.size(),m_memoryRefSet.data(),fence) failed with GR_ERROR_DEVICE_LOST. GPU: "AMD Radeon HD 7700 Series" (26685) Driver 37752832

After clicking OK on it I get similar error messages popping up again and again until I go to task manager and Endtask on BF4.

This happens mostly after some time computer is active and a reboot usually helps for some hours or so.

#2 I think the problem might be with the display driver itself, which is AMD Beta 14.2, because I would occasionally start the computer, do nothing, then go away, and when I come back it will say that MM driver has stopped responding and has been restarted, so no BF4 running is always needed to trigger some problems.

#3 Also, it seems that BF4 gets stuck more (which didn't happen with 14.1 Beta driver nor with DirectX and non-Beta AMD previously): the fps drops to a halt, and the game loops through some sound sequence - eg some shots until you reboot the computer.

In general, it seems that BF4 now drives the graphics card harder than before, as the computer gets much hotter during playing, and I think #3 might be connected to card overheating. Didn't happen with AMD official drivers and directX previously.
