Posted on June 28, 2020 by Roman

One more system check tool to quickly enumerate available monitors (using DXGI), take snapshots and was them in PNG files (using WIC). Apart from straightforward desktop snapshot taking, the tool offers a few more functions: Goes through the entire list of available video adapters and connected monitors Uses three slightly different methods to do the…

Is my system a hybrid (switchable) graphics system?

Posted on January 3, 2020January 5, 2020 by Roman

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…

AMD PowerXpress/Enduro switchable graphics DXGI issue

Posted on December 28, 2019December 28, 2019 by Roman

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 […]…

MediaFoundationDxgiCapabilities: GPU preference & Hybrid GPU systems

Posted on December 27, 2019 by Roman

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:…

Presenting Shadertoy output at low latency with DXGI and Direct3D 11

Posted on October 13, 2019October 14, 2019 by Roman

A few nice updates today for a Direct3D 11 shadertoy rendering tool I posted earlier on here. As a load tool, it benefits from some flexibility and it is also a demonstration of hardware capabilities as well. First of all, the -EnumerateAdapters switch is now more verbose about DXGI and prints more of flags, e.g.:…

MediaFoundationDxgiCapabilities: with AMF SDK H.264 encoder related data

Posted on October 4, 2018October 4, 2018 by Roman

Yet another post on AMD AMF SDK and hopefully a helpful tool reference. I updated one of the capability discovery applications (MediaFoundationDxgiCapabilities) so that it includes a printout of AMFVideoEncoderVCE_AVC related properties similarly as they are printed for Nvidia video adapters. Information includes: runtime version (and its availability in first place!) maximal resolution, profile and…
