The problem we were facing that the Tablet’s resolution changes to lower after connecting the system to projector/HD TV. Our System Support 1920x1080” resolution, We can connect to any HD TV /Projector through “Display Port to HDMI cable”. In our Win8 system we have a requirement to connect the Tablet to external display, Tablet has only “display port” and we can connect to any monitor which has display port. I have an issue, I am posting here because I am not finding how to put a new question: I hope Intel review this driver issue a soon as possible and fix it.
If someone need my test code snippets or any other details feel free to contact me. And even more it outputs debug message that device memory is exhausted:ĭ3D11 ERROR: ID3D11Device::CreateBuffer: CreateBuffer returning E_OUTOFMEMORY, meaning memory was exhausted. With the same tests my secondary AMD R7 265 works fine, correctly creating and releasing D3D11 resources. I have tested this on current HD 4600 driver (154010.4300) and beta (20.) which available for download here. Buffer 1Mb sized r esource creation fails after 1450-1550 iterations, texture 2D 1Mb sized resource creation fails after 24000 iterations. Everyone can write and run test this issue simply creating a loop with D3D11 resource creating and releasing inside loop body. It simply does not do it after calling Release() D3D11 API method as it should be and device memory still stay allocated. I have run my own tests on Intel HD Graphics 4600 regarding memory allocation and can say that driver has problems with releasing resources. ~1500 iterations with 1Mb sized buffer resource and ~24500 iterations with 1Mb sized texture 2D resource leads to removing D3D11 device (possibly memory leaks) Infinite iterations with creation and releasing D3D11 resource should be okay (no memory leaks) Write simple loop with creating and releasing the same resource (buffer or texture) inside it.
Create hardware D3D11 device on Intel HD 4600 adapterĢ. Occurs on non-Intel GPUs?: only on Intel 4th genġ. My application uses Direct3D11 API.Īfter successful device creation and futher resource allocations, Direct3D debug runtime outputs:ĭ3D11 WARNING: ID3D11Device::RemoveDevice: Device removal has been triggered for the following reason (DXGI_ERROR_DRIVER_INTERNAL_ERROR: There is strong evidence that the driver has performed an undefined operation but it may be because the application performed an illegal or undefined operation to begin with.).
