Intel Graphics Driver 26.20.100.7584 released (Vulkan 1.1.127 – 2020.01.03: article updated)


Intel logo

 
Intel has published a new graphics driver for its GPUs (Intel 6th, 7th, 8th, 9th and 10th Gen processors) on Windows 10. This new driver (version 26.20.100.7584) comes with the following changes:

GAMING HIGHLIGHTS:
– Build amazing things in DRAGON QUEST BUILDERS 2 and fight your way through the Underworld in Hades Steam Early Access on Intel UHD Graphics or better.
– Battle against the machines in Terminator: Resistance, dominate your enemies in the MMORPG/RTS hybrid Kingdom Under Fire 2 and learn the truth behind the Phoenix Mirror in Shenmue III with Intel Iris Plus graphics or better.

DEVELOPER HIGHLIGHTS:
This driver adds support for the following Vulkan extensions:
– VK_KHR_SHADER_FLOAT_CONTROLS
– VK_KHR_SPIRV_1_4
– VK_KHR_separate_depth_stencil_layouts
– VK_EXT_FULL_SCREEN_EXCLUSIVE
– VK_NV_device_diagnostic_checkpoints

KEY ISSUES FIXED:
NOTE: This driver also contains security improvements.
– Intermittent crash or hang may be observed in Call Of Duty Modern Warfare 2019* or while launching DOTA2 on 10th Gen Intel Core processors with Iris Plus graphics.
– Minor graphics anomalies may be observed in NextPVR, Code Vein*, NBA 2K20*, Solidworks 2018/2019 and Adobe Fresco applications.
– Intermittent crash or hang may be observed when launching or closing ARCHICAD application.
– System restart with BSOD observed on 10th Gen Intel Core processors with Iris Plus graphics after the system boots with the lid close state on single display embedded laptop panel.
– When connecting Apple* 6K monitor on 10th Gen Intel Core processors with Iris Plus graphics, max resolution is only up to 4K.

 

Downloads

 
Quick test of this driver on an Intel Core i7-8700K (with an UHD 630 GPU):

I installed and re-installed several times this driver but there is no way to get a decent OpenGL support. The driver v7584 removes the OpenGL 4.6 support and only a generic OpenGL 1.1 is available. If I install the driver v7463, the OpenGL 4.6 support is back.

So here is the OpenGL support of v7584 😀

- GL_VENDOR: Microsoft Corporation
- GL_RENDERER: GDI Generic
- GL_VERSION: 1.1.0

 

UPDATE (2020.01.03)
I finally managed to install this graphics driver. The secret was to manually install the driver by selecting at some point the iigd_dch.inf file.

Now OpenGL 4.6 support is there:

- GL_VENDOR: Intel
- GL_RENDERER: Intel(R) UHD Graphics 630
- GL_VERSION: 4.6.0 - Build 26.20.100.7584
- GL_SHADING_LANGUAGE_VERSION: 4.60 - Build 26.20.100.7584
- OpenGL Extensions: 250 extensions (GL=230 and WGL=20)
- OpenGL SPIR-V Extensions: 4

The OpenGL support is similar to the one exposed in v7463.

Vulkan support

On the Vulkan side, there is no problem, Vulkan is there. Intel v7584 exposes Vulkan 1.1.127 and adds 5 device extensions compared to previous v7463:

VK_EXT_full_screen_exclusive
VK_KHR_shader_float_controls
VK_NV_device_diagnostic_checkpoints
VK_KHR_separate_depth_stencil_layouts
VK_KHR_spirv_1_4
