DX12: 50% CPU power reduction/50% FPS increase.

Comon don't bash MS for delivering for over 10years the only good API (yeah we had opengl but it was jsut a pain to use).

Anything before DX8 was abysmal and I came close to gouging my eyes out with spoons when working with DX5, whereas OpenGL just worked.

Actually FMPOV DX12 is not only "inspired" my Mantle but a knee-jerk reaction from MS to keep the people on their Windows platform.

There's a lot of people who have said similar, and a lot of other people rather angrily disagreeing with them.

Mantle vs DX 11.2 .....

My specs are below, tried both in various games including BF4, Thief.

DX 11.2 far better than Mantle. Crisper graphics, avg about 10Fps MORE and no memory leak.

The force is weak with Mantle.

Looking at your sig, is Mantle not aimed at improving FPS for rigs with significantly less capable CPUs?

Ben, if you can tell us, have FD already found porters to Mac OS X (job ads still were at frontier.co.uk some time ago) and is there any info which will be target version? I hope latest one because that finally supports OpenGL 4.1.

Seems some people get the mantel reference I made others not so much to put it more simply the hardware vendor need to have a unified approach to direct hardware access, that can leave out OS dependant APIs. OpenGL is ok but being an open project takes a very long time for any thing to change going forward and unfortunately tries to keep too much compatibility with older hardware to it's detriment mostly likely due to it's overly long dev cycle. whether it's mantel, OpenGL+ or something new does not mater.

And the comments about mantel not adding much to what is already considered a performance PC try think about it as performance tuning a race car it's not ever going to add big numbers (DX12 would not add big numbers to that system ether dispite what the marketing hype tries to about) but where it matters is the average level PC would see a boost.

Running at 4.4Ghz on I7-3770K with a R9 290X currently so not that it matters for me ATM, haven't found a game yet that I cant run with V-sync with full options on at good frame rates even StarCitizen which is awfully optimized I still get 45min-55avg with ultra settings. CPU is next in line for an upgrade when it's warranted.

OpenGL is not open source project, it is committee driven open standard. Previous slugishness of OpenGL change has been because of CAD industry - you can't imagine how much software depends on that thing.

Now CAD have found solution to their woes with promise to keep OpenGL 4 alive for them, and OpenGL 5 being complete redesign, more multimedia/games driven API. That said, 4.1 - 4.5 is already very usable to get good looking graphics (as ED), just need good driver support.

Anyone interested in Directx 12 should ahev a look at this

http://blogs.msdn.com/b/directx/archive/2014/03/20/directx-12.aspx

and if you want early access to DirectX 12 try the early access programme

Shouldn't this thread be in the hardware section of the forum - such as here:

My 2cents is that Directx12 won't be appearing on W7 alas

Thanks for the link. One can never have enough information.

It usually takes a long time before games see the result of new technologies. For example, many of the benefits of dx10 weren't used because lots of developers were comfortable with dx9.

Tiling is an exciting part of dx11.2 but I'm not sure I've heard of it being implemented in a game yet. It would surely be a great fit for ED.

Microsoft will use it to try and shift copies of Windows 8/8.1. Personally, unless a game won't run at all on Win 7 I will be waiting until Win 9 appears.

I have to use 8.1 at work for some things and its horrible, to me at least.

ED uses DX10 feature set as far as I know. Maybe in future expansions could require some new features, but we will see.

I wouldn't blame consoles alone on stagnation of DirectX. I think they reached level of feature set which is "good enough" for most of the games devs can think about.
