Hello, I have an AMD Radeon HD8750M (1GB VRAM) and GPU-Z shows that this GPU is not compatible with DirectX, but I've checked in AMD website and it is. I think this is a problem of switchable graphics as Intel HD 4000 shows compatibility and appears in dxdiag. Here are my full PC specs and GPU-Z screenshots:


  • Processor: i5-3230M (2.6Ghz up to 3.2Ghz)
    Graphics Card: Intel HD 4000 and dedicated AMD Radeon HD8750M (1GB VIDEO RAM)
    RAM: 4GB
    OS: Windows 8.1 (64-bit)

Screenshots:
AMD
Intel

I really need the DirectCompute5.0 (Shader Model 4.0 or greater) working on the AMD and that is what is not enabled. And so you know I've updated every single graphic driver but GPU-Z keeps saying Intel is from 2012 (I've checked and it's from 2015) and I need AMD Driver on v15.2 for the app I want to use

Thanks in advance

Sorry, I meant the driver version shown in GPU-Z is from 2012 but the one I have installed is from 2015. I have already set on Catalyst to use AMD and it uses it but something about OpenGL or DirectX (probably the last one) doesn't seem to be working well.

I have DirectX 11 (I think I even have 11.2)
 
If you have graphics or driver issues, one of the most common fixes is a clean uninstall and removal of your graphics drivers.

To uninstall your drivers, first download and run Display Driver Uninstaller, and follow it's recommendations of booting into safe mode and ect.
(This is a direct download link so you don't grab the wrong version)
http://www.guru3d.com/files-get/display-driver-uninstaller-download,20.html

You'll download a compressed file called "[Guru3D.com]-DDU.zip"
Right click and choose extract.
Go into the folder and run the DDU v##.##.exe
This will extract more files to this folder.
Run Display Driver Uninstaller.exe
Choose Yes when it asks you to boot into SafeMode.
After you've rebooted into safe mode.
When DDU comes up, if it hasn't selected your GPU manufacturer (Nvidia/AMD/Intel) then choose it from the drop down list
Press the Clean and Restart option
If a window comes up asking to disable the Windows automatic installation of display drivers click yes.

After (or before removing the old drivers, just put the new ones on the desktop or somewhere handy) rebooting back into Windows, manually download the latest drivers from Nvidia or AMD, don't use auto detect, choose you GPU model and OS from the drop down lists.

I already did all that. I've finally asked because I couldn't find the solution on my own
