The application in previous post Is my system a hybrid (switchable) graphics system? is implemented in C++/WinRT, which I finally decided to give a try. For authoring and consuming Windows Runtime APIs using C++, there is C++/WinRT. This is Microsoft’s recommended replacement for the C++/CX language projection, and the Windows Runtime C++ Template Library (WRL). The real question…
There is a number of systems out there equipped with multiple GPUs which work cooperatively. The technology itself started from Integrated graphics processing units which brought a “free” GPU into system. Such system equipped with an additional discrete card obtained two GPUs at a time and from certain point it was a challenge to not…
Yesterday I wrote about the NVIDIA Optimus problem with DXGI where Output Protection Manager API reported Intel certificate for NVIDIA DXGI adapter. AMD hybrid graphics known as “PowerXpress” (and most recently as “Enduro”) exhibits the same behavior: Adapters AMD Radeon HD 8850M Intel(R) HD Graphics Family Adapter: AMD Radeon HD 8850M Vendor Identifier: 0x1002 […]…
I added a section that enumerates DXGI adapters with the help IDXGIFactory6::EnumAdapterByGpuPreference – this is included into the produced output. Unfortunately the method does not distinguish between dual GPU systems, such as with discrete GPU and additional CPU integrated Intel GPU… DXGI Capabilities NOTE: Baseline capabilities are corresponding to DXGI 1.1 Windowed Stereo: 0 DXGI_FEATURE_PRESENT_ALLOW_TEARING:…
Bits of Rainway Pulsar technology at work in this test run. The big monitor is a part of desktop system, by the way, not a high end one: Radeon RX 570 with two monitors, one of which is encoded into H.264 and streamed over network to two pieces of hardware: Intel NUC with a 2K…
An interesting Media Foundation question on StackOverflow: Weird connection between CoInitializeSecurity() and Media Foundation Encoders A developer has reasons to discard standard COM security and go RPC_C_IMP_LEVEL_ANONYMOUS. Surprisingly this has effect on Windows Media Foundation API in the part of available codecs (Media Foundation Transforms). Sample code: CoInitializeSecurity line in the code above removes the…
XAML MediaPlayerElement control/class is exhibiting a ridiculous bug on Xbox One: once you are going fullscreen the control is not showing the video correctly. A texture is assumed to be rendered in full and it is cropped instead (left top quarter of actual video or alike). I saw this before but at that time I…
