Hi Rahul, I believe this feature will be supported on all APUs and discrete GPUs on Windows 8.1.
View ArticleRe: DX11.2: Tiled Resources support on AMD GPUs
Currently tiled resources feature is supported on the HD 7790 and the Kabini based APUs (E.g. A4-5000). Support for all GCN hardware will be available in the coming months.

Re: DX11.2: Tiled Resources support on AMD GPUs
In answer to my own question, I spoke to someone at AMD who confirmed that despite the release notes saying otherwise, Tiled Resources are not supported in the current driver.

Hello, I've successfully written my own Direct3D 9, 10, and 11 samples using the AMD QBS and I know it works great. However, one of the biggest complaints I have with the SDK and/or driver is that I...
View ArticleDirectCompute and "Dual graphics": Identifying the card executing kernel
I am writing a pure-compute app using DirectCompute. The application is not doing any graphics. The app is running on a "dual-graphics" enabled notebook (A10-5750 + 8750M). They are unfortunately...

Re: DirectCompute and "Dual graphics": Identifying the card executing kernel
I think I now understand how this works. You can click on "Configure switchable graphics" from the CCC tray icon and then explicitly assign either "Power-saving graphics" (which I assume is integrated...

Printing ISA from HLSL compute shader?
Is there a tool that prints ISA from HLSL, the way you can export ISA from OpenCL for AMD platforms? I have used ShaderAnalyzer (which is great) but AFAIK it uses compiler from an old Catalyst version,...

Re: Stereo OpenGL
The behavior you're seeing is by design and is a part of Windows 8. It is not specific to OpenGL or the AMD driver. For instance, even if you run a D3D 11.1 stereo application that destroys its stereo...

To answer my question (partially), I have verified that the extended double precision instructions are at least supported on GCN cards. However, it appears (surprisingly) that Trinity/Richland APUs do...
View ArticleglDrawArraysIndirect not setting gl_VertexID correctly?
I'm not 100% positive what the correct behavior is here, but on NVIDIA hardware, gl_VertexID = first + [vertex index]. So if I specify first=2, count = 6, then the values for gl_VertexID in each...

Re: glDrawArraysIndirect not setting gl_VertexID correctly?
I haven't tested it with glDrawArraysIndirect, but for example with glDrawElementsBaseVertex(mode,count,type,indices,basevertex): - on AMD series 2 to 6, the built-in shader variable gl_VertexID...
