Provide a detailed description of the issue AND 'does it fail every single time, or only sometimes?' If you can offer a % rate please do.
the 3dmark dx12 test causes graphical defects to occur
in the image below some of the vertex's of objects are not being stored correctly in l3 cache (breaking cache coherence)
the test works by testing how many draw calls the GPU can handle to help the GPU the same texture is used on all objects

HP Pavilion 15 Notebook PC
Hybrid or switchable graphics system? ie Does it have AMD or NV graphics too?
no

Hello zeqzy,
Could you please provide the specific model of your HP Pavilion 15 Notebook PC?
Could you please send the DirectX Diagnostic* report by running dxdiag and clicking on the "Save All Information" Button.
Meanwhile, I suggest updating the graphics drivers to the latest version available from the manufacturer.
Regards,

HP Pavilion Notebook - 15-p199na
the latest driver that both HP and Intel provide is the same driver i used to report the issue (HP only package the published driver so that there support assistant software can install it easier)
i have tested the app again and there are still graphical bugs with it
also when can support for 12.0 or better 12.1 https://msdn.microsoft.com/en-us/library/windows/desktop/ff476876%28v=vs.85%29.aspx https://msdn.microsoft.com/en-us/library/windows/desktop/ff476876%28v=vs.85%29.aspx
considering the speed of cache memory the score is not good
the graphical defects do not appear at the beginning of the test and only appear after passing 1,000 draw calls a frame
I have tested all drivers that have the directx 12 user mode driver support (igd12umd64.dll) and the windows 10 beta driver, 10.18.15.4248 and 10.18.15.4256 all incorrectly draw the objects on the screen
however the new driver 10.18.15.4279 does not draw the objects that where being incorrectly drawn anymore

the new driver 20.19.15.4300 has improved the situation now there are very few objects that are being drawn incorrect
according to https://downloadmirror.intel.com/25489/eng/ReleaseNotes_GFX_15.40.10.4300.pdf https://downloadmirror.intel.com/25489/eng/ReleaseNotes_GFX_15.40.10.4300.pdf this has being fixed
Hello zeqzy,
That is correct. According to Release notes "Graphics corruption when running 3DMark DX12 API Overhead Feature Test Windows* 10 64-bit" was fixed.
Please take into consideration we continuously strive to improve the quality of our products to better serve our users and appreciate feedback on any
issues you discover and suggestions for future driver releases.
