I don't see why they delayed the driver due to "bugs" but released it buggy anyways 
People were all on about "Oh, we don't want them to release it broken/buggy etc" hence delay, but they release it in a state anyway and now it's "Well it's a beta",

That's misinformation. The driver was delayed due to a specific install issue rather than just typical driver bugs.

I'd prefer they just flat out delayed it another month, because it's not in a truly usable state right now.

Just sayin
Nothing to do with the CPU its self, its the DirectX API thats not able to make full use of any CPU running, Mantle makes much more use of that CPU.
Wrong, this was made clear right from day one
There is a performance gain even from Intel's £500 12 thread chips
No, thats you making that assumption.
Again your misunderstanding of how Mantle works and your assumptions are all that lead you to belive that.
Its not so much that your cynical, although you are, its more that you simply don't understand what your reading.

bf4 is really bad for me at the minute, completely different from yesterday horrible performance on both dx11 and mantle mode. talking sub 60 frames constant.
also these 4 white boxes flash up every so often on the right hand side.

With your same argument you could argue that mantle is in fact mostly for ultra-enthusiasts.
Because of the way mantle works someone with two or three R9 290X's is going to see more of an increase in performance than anyone else (and likely in any game/scenario). Even an i7 4930k at 4.5 GHz would be a bottleneck all the time with multiple R9 290X's.
Granted, it does suck a bit that mid-high builds with well matched processors (e.g. an i5 4670k with an R9 280X) will see minimal gains. But on the flip-side it looks like people with weak CPU's and people with Xfire will see substantial gains.
It's still beta too, so it remains to be seen if there can be a respectable gain purely from the GPU (even 10% would be amazing, since it would be from nowhere). That probably won't happen, but the main point is that a lot of games are CPU limited, and a lot of future games are very likely to be too, since we're shifting so much towards multiplayer.
Just sayin
That was before i knew the reason though so was speculating.

But that doesn't change anything.
You were on about them releasing a none bug filled driver, and they've released a bug filled driver.
It's all well and good saying Mantle's in beta, in which case it should never be put into games yet.
If Thief's working perfectly, then we know Dice messed up, but if Thief is broken with Mantle, then it's plain not ready yet to be implemented, and dev's shouldn't really be playing with it as far as I'm concerned as I feel that's compromising the end product.
When DX11 came out, everything I ran on it was perfect, the Heaven benchmark etc, Dirt 2 with DX11.
It does, the bug meant the driver would not install at all, so im glad they delayed it to fix it so i could have a small taster of what's in store. Driver works fine for me on single card and i see 14% improvement in performance and the smoothness in the game makes it feel like a different game. Crossfire does not work at all for me though, but it says that in the notes so that was expected.
DX11
Mantle
14% improvement for me. Single 290 at stock. Can't test crossfire yet unfortunately.

Let me try and put this in simple terms for Besty and anyone else who might be misunderstanding this.
The CPU computes Physics calculations, The API, (DirectX or Mantle) process those Physic calculations for the GPU.
If the CPU is capable of calculating 50.000 Physics handles at any given time but the API can only Proccess 5.000 Handles at that time then that is all the GPU / Game will get.
So, The game may ask for 5.000 parallel Physics handles at a given time, the CPU will calculate them, Direct X will process them, if the game asked for 8.000 parallel Physics handles the CPU will do it but Direct X will take longer to process them as it can't do it in parallel, it being limited to 5.000, the result is the game slows while its waiting for Direct X to catch up (the bottleneck)
Mantle can process a lot more parallel Physics handles at a given time, lets say 30.000, so when the game asked for 8.000 Mantle is able to hand them over when its needed, the result is it does not slow.
So it does not matter how powerful your CPU is or isn't, Direct X is the weak link. The computer, the game is only as fast as its weakest link.

I gave it another go using DDU this time. Still the same BS and now alt+enter turns my second monitor into a nice black screen. (must have alt+entered 250 times).
Stutter.. freezes every 10 seconds.. using up to 2.8GB of vram with only 2xMSAA.
Im on 13.12 now until at least 90% of AMD card owners start saying that a future driver is awesome.
I just cant be arsed with the hassle and wasting of time so im gona let everyone else test drivers for me.
Peace out o/
Edit.. oh and right now i cant even join a server or even the freakin test range after 15 attempts.
Im done.

Understandable. Worth trying but i guess in your case with more than one screen its better to wait for a newer driver. Let me tell you, you're in for a nice surprise as and when you do get to try it. Always best to check release notes for things like this, can save yourself some heartache sometimes.
Known Issues of 14.1
Intermittent stuttering or stability issues may occur when utilizing Mantle with AMD CrossFire™ technology in BattleField 4™
Mantle performance for the AMD Radeon™ HD 7000/HD 8000 Series GPUs and AMD Radeon™ R9 280X and R9 270X GPUs will be optimized for BattleField 4™ in future AMD Catalyst™ releases. These products will see limited gains in BattleField 4™ and AMD is currently investigating optimizations for them.
AMD Eyefinity configurations utilizing portrait display orientations are currently not supported by the Mantle codepath in Battlefield 4™
Had a few "BF4 has stopped working" on 13.12 with this latest BF4 patch.
I don't know what the problem with Mantle is in BF4, it works perfectly in the Star Swarm app.
I think it may be a case of *DICE strikes again*
