Description

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

Hardware (HW)

Brand and Model of the system.

HP Pavilion 15 Notebook PC

Hybrid or switchable graphics system? ie Does it have AMD or NV graphics too?

no

Make and model of any Displays that are used to see the issue (see note2 below).

LFP = Local Flat Panel (Laptop panel)

EFP = External Flat Panel (Monitor you plug in) 

LFP 1366 x 768 (32 bit) (60Hz) SDC4951

How much memory [RAM] in the system (see note2 below).

8192MB RAM

Provide any other hardware needed to replicate the issue.

ie: Cables&brand, cable type [vga, hdmi, DP, etc], dock, dongles/adapters, etc

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,

Caesar B.

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

the new driver ( 4279) has made the problem worse now objects that where drawn incorrectly are not not drawn at all (also creating falsely higher scores)

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.

fixed for the iris 5100 in driver version 4326

the table of issues resolved assumes that all GPUs have had the issue fixed when that may not be the case
