my cpu is i7 HD4000
i encode two 1920*1080 and render them this time the cpu is low about 30%
but when i add another one the cpU become 70%
i am confused
does that mean when the gpu is busy ,the media sdk will use cpu to encode the video ?
thanks for any suggestion
Rendering impact on Processor and/or Intel HD Graphics will depend heavily on the methods used for rendering, and will also depend on OS version and DirectX framework version used.
To verify optimal behavior/performance of Media SDK and HW codec acceleration I suggest you remove all rendering and file writing.
