Intel® Vulkan BETA 15.40.20.4404 Graphics Driver on Surface Pro 4

[IAldu]

Testing Vulkan on Surface Pro 4, Dialog error appears when the code tries to LoadLibrary(igvk64.dll) or the 32bit version. Any ideas?

Looks like a version mismatch. Regarding the API version the Intel driver is meanwhile out-of-date.

Re-check with http://vulkan.gpuinfo.org/download.php Vulkan Hardware Capability Viewer

and / or

http://www.geeks3d.com/vkz/ VK-Z - Vulkan capabilities and extensions viewer

Same error with these apps.

Try the runtime installer coming with the SDK - https://vulkan.lunarg.com/ https://vulkan.lunarg.com/

The only available SDK on LunarG for download is 1.0.8 and with that does not work. I tried uninstalling the SDK ensuring that no vulkan-1*.dll left in the system folder so the Vulkan Hardware Capability fails for the missing dll. Then I have installed the VulkanRT that comes with the Intel driver (1.0.3.1), and that one doesn't work neither, the same error as with 1.0.8 appears.

Hi Ivalduan,

I try to replicate your case and my Surface Pro 4; it only accepts the manufacture Graphics driver, it is important to mention that we sell our Intel chipsets and processors to third party manufacturers and they design their own computers with their own features, settings and capabilities. For that reason they design their own drivers, to meet the exact specifications on their computers. If your computer is having problems with our generic Intel graphics drivers, the best you can do is install the latest customized driver released by the OEM (Original Equipment Manufacturer).Regards,Hellen

Hello Hellen,

thanks for your response and for the time trying to reproduce the problem. With the OEM graphics driver installed in the system is true that you cannot install the drivers from Intel, but it is not difficult to uninstall the OEM version of the graphics driver, and then install the latest one from Intel. As I expected, if the processor is the same (Intel® HD Graphics 520) it shouldn't be any problem and I haven't notice anything malfunctioning except for the Vulkan support.

I would expect to be able to try Vulkan on the Surface Pro 4, it has a 6th generation Intel processor and should be supported as expected for engineers trying to develop graphics applications for it.

Thanks,

Ivan.

Many thanks Hellen,

this driver installation or something did the work and the error appearing before disappeared. I don't know what was wrong, I took previous installer from here and it seems to be the same:

Maybe it has been one of the latest system updates from Microsoft this week.

Thanks.
