DirectX 12 announced: Get the deets here

DirectX 12 - What's the big deal?

DirectX 12 early access program

AMD Press Release - DirectX 12

NVIDIA Blog - DirectX 12


Q: Should I wait to buy a new PC or GPU?
A: No – if you buy a PC with supported graphics hardware (over 80% of gamer PCs currently being sold), you’ll be able to enjoy all the power of DirectX 12 games as soon as they are available.

Q: Does DirectX 12 include anything besides Direct3D 12?
A: Also new is a set of cutting-edge graphics tools for developers.  Since this is a preview of DirectX 12 focused on Direct3D 12, other technologies may be previewed at a later date.
Q: When will I be able to get my hands on DirectX 12?
A: We are targeting Holiday 2015 games.

Q: What hardware will support Direct3D 12 / will my existing hardware support Direct3D 12?
A: We will link to our hardware partners’ websites as they announce their hardware support for Direct3D 12.

Yes, since v0.6.3.9, GLSL Hacker supports MRT.

There should be a demo in the code sample pack /host_api/MultipleRenderTargets/

To create a render target with two color buffers:

Code: [Select]
num_color_targets = 2
rt01 = gh_render_target.create_v2(width, height, num_color_targets)

When you need to bind color buffers as textures, just do:

Code: [Select]
gh_texture.rt_color_bind_v2(rt01, 0, 0) -- Color texture 0 on texture unit 0
gh_texture.rt_color_bind_v2(rt01, 1, 1) -- Color texture 1 on texture unit 1

In the fragment shader, just declare several outputs:
Code: [Select]
out vec4 FragData[2];

Let me know if the code sample pack is not up to date.
Hope that helps.

Can I bind multiple render targets in one render pass? like implementation for Deferred Rendering.
I read the example code, it bind one render target for each pass :(
Welcome OpenCL™ developers and enthusiasts!  Here you will find a BETA version of our OpenCL 1.2 driver which includes HSA extensions that implement a subset of the functionality from the recently ratified OpenCL 2.0 specification.  This functionality is built on top of the HSA capabilities in AMD’s recently launched 4th generation APU desktop processors (formerly known as “Kaveri”) and include much of the Shared Virtual Memory and Platform Atomics functionality in the OpenCL 2.0 specification.

This BETA release is intended to enable developers who wish to prototype applications using this OpenCL 2.0 functionality now, rather than wait for the AMD driver compatible with OpenCL 2.0. OpenCL 2.0 will be our primary enablement path with a new driver available later this year to enable these features for developers, and so AMD does not plan to deliver a production version of OpenCL 1.2 with these extensions. OpenCL 2.0 will be a major milestone for our industry, and AMD expects it to become the developer tool of choice for heterogeneous computing enablement.

I posted OpenCL 2.0 functions list here

RTFM and edit path and registry

Recent regular Catalyst betas already contain HSA core, check with CLINFO.EXE
  Platform Version:             OpenCL 1.2 AMD-APP (1411.4)
  Platform Extensions:             cl_khr_icd cl_khr_d3d10_sharing cl_khr_d3d11_sharing cl_khr_dx9_media_sharing cl_amd_event_callback cl_amd_offline_devices cl_amd_hsa

NVIDIA, AMD, Intel Explain How OpenGL Can Unlock 15x Performance Gains
If you want to get a developer’s attention, all you need to do is start dropping whole numbers.
Offer something that’s not 1.2 times better — but two or three times better — you know you’ve got them.

With OpenGL, an open, vendor-neutral standard, developers can get significantly better performance – up to 1.3 times. But with a little tuning, they can get 7 to 15 times more performance.

3D-Tech News Around The Web / Civilization V Gets OpenCL Update for Mac Pro
« Last post by Stefan on March 21, 2014, 01:52:58 AM »
Aspyr has just released a new update for Civilization V that, among other improvements, takes advantage of the second video card in the Mac Pro.

Mac gamers that play on the Mac Pro will now be able to fully take advantage of the machine’s second video card, which means better visuals and improved performance for the critically acclaimed strategy game. In particular, Civilization V on the Mac Pro will now support 4k monitors while running into fewer crashes. Additionally, the game should run faster (meaning less waiting in between turns in late-game situations).

This update makes Civilization V the only Mac game that currently supports the second video card on the Mac Pro. It should automatically download and install for Steam users; Mac App users can head to the Mac App Store to get the update. For even more info on how to take advantage of the new update, check out the knowledge base article over at our Support site.
