Windows 10 DiectX : Runtime Version with Hardware supported version

[LJiaH]

Hi all,

I just upgraded to Windows 10.

The Intel Graphics Driver download site have the graphics driver for Windows 10 that match with my processor and graphic cards.

Processor: 4th Gen Intel Core i7-4510U

Card: Intel HD Graphics 4400

OS: Windows 10

Intel Graphics Driver : 15.40.10.64.4300 (20.19.15.4300)

The new driver that I downloaded from Intel site contains the newest DirectX 12.

After I installed, the system information inside the Control Panel shows Directx version:

Runtime Version : 12

Hardware Supported version : 11.1

Inside the Directx Diagnostic Tool. It shows version 12 too.

I have question.

1. Will the new "Graphics Driver" (Directx 12 with Windows 10) works with the Hardware Supported Directx version (Directx 11.1) "Graphics Card"??

2. Will the new graphics driver support my graphics card??

3. Or, which graphics driver should I download??

The Intel Driver Update Utility gives a 3rd Gen Driver for me after I scan for new driver.

But I'm running on 4th Gen Processor and Intel HD Graphic 4400.

Which driver should I download??

Sorry about my English.

Thank you.

You should use https://downloadcenter.intel.com/download/25489/Intel-Graphics-Driver-for-Windows-10-15-40-4th-Gen- Download Intel® Graphics Driver for Windows® 10 [15.40][4th Gen] driver for Windows 10.

Will the new "Graphics Driver" (Directx 12 with Windows 10) works with the Hardware Supported Directx version (Directx 11.1) "Graphics Card"??

Yes. Actually, Direct3D capabilities are advertised by driver to apps as "feature level", so app written to Directx12 API will use available feature level for rendering, in case of Haswell it is D3D_FEATURE_LEVEL_11_1.

Will the new graphics driver support my graphics card??

Yes.
