Whats AMD Mantle and why doesnt it work?

PS I have an AMD card

[MKJoker]

It's AMDs version of Directx. It's supposed to make lower cpus better if you're running an AMD GPU. I don't know the specifics, but that's what I understanda bout it.

It's supposed to make it so the game can talk directly to the hardware instead of going through the OS first.

You need an AMD card with GCN architecture to use it.

Seems to be working okay here, or at least I can launch and play the game with the Mantle option. Takes a while (~15-20 sec) to return to the OS when exiting the game and I haven't compared performance to the DirectX version, but no issues. Are you running the latest drivers? I saw mention in an article that it would require the 14.9.2 beta Catalyst driver, which doesn't appear to have been released yet, but seems to be running okay on the 14.9.1 beta.

Firstly, you need a GPU from the Radeon HD 7xxx or the recent R7-2xx or R9-2xx series.
Secondly, you need a recent driver. (The first AMD driver with Mantle support was either 14.1 or 14.4, I don't know for sure)

Then you're set to use Mantle.

Mantle's main purposes is that it has a much lower CPU load than the DirectX draw calls.
That means your CPU power can be used elsewhere (mainly AI calculations and other game logic).

Doesn't work for me either, even though I'm using an A10-7850 with R9 290 GPU. This is the ideal Mantle setup since the CPU power of the A10 is kinda underwhelming. But when I try to start the Mantle version, nothing happens.

Do you have a recent GPU driver? Mantle doesn't work with an outdated driver.

how do I know if my card has GCN Architecture?

System specs?

I have an R9 270x, using Catalyst 14.9, and the Mantle version crashes at the title screen.

my graphics card is AMD Radeon - R7 200 series

Radeon HD 7xxx, Radeon R7 and Radeon R9 are GCN architecture.
Which includes your GPU. You should be able to use Mantle with a recent AMD graphics driver.

If you can't, it's the game's fault.

I was running on 14.4 which should've been good enough for Mantle support.
Updating to 14.9, however, solved my issues! Game is running like a charm for me now.

Great. From what I can decypher in my limited searching skills my HP Pavilion dv6 with

AMD A8 3500m APU
&
AMD Radeon HD 6620g

does NOT support the mantle.

Am I correct or can someone help me? Tired of the dx11 exe crashing.
From what I can gather dx12 won't work on this thing either.
