Cannot run Time Spy on RX 480?

[青木 果報]

I've got an RX 480 and Radeon Software 17.2.1 (which is the latest WHQL driver), and when I try to run Time Spy I get a "feature level" error. I dug around a bit and noticed that the drivers need to be "WDDM Model 2.0" to fully enable DX12 functionality, but DXDIAG lists my feature level as only 11.2 and the driver model as only WDDM 1.3.
Does this mean I'm unable to run the Time Spy benchmark until AMD fixes their drivers?

The RX 480 is fine, it's just that your version of Windows is obsolete.

Time Spy requires DirectX 12, which is a Windows 10 exclusive. You cannot run it on Windows 7 or 8.1, as these operating systems do not support DirectX 12 nor WDDM 2.0 drivers.

I have Windows 10 build 10240, which I still had when I ran time spy on my 960 as seen here: http://www.3dmark.com/spy/65496
Nothing about the system has changed since that run except for the GPU and its drivers.

14393 is only two months newer than 10240, and has never been pushed to the public as far as I'm aware. It's still labeled as a release preview anyway. I'm using 15061, so not actually sure what the last release pushed to te general populace was, but I thought it was 10240.

I'm on 10240 because I don't like the way microsoft has started handling updates. I want to choose what to install on my pc and what not, and the OS installing stuff on its own is the last thing I want. I updated my licensed win7 to 10 and disabled windows update right afterwards and it's been that way since august 2015.

At least on NVIDIA side, latest video drivers will not install except to the November Update ( 10586) or later. I haven't checked what the status is on AMD side, but I wouldn't be too surprised if there were similar limitations. At least one thing is certain; No multi-GPU mode will work on older Win 10 as DX12 prior to November Update did not have working DX12 multi-GPU at all.

Our test lab tests only against latest public release of Windows 10 and against the upcoming next release (insider preview). These work.

If DXDIag says WDDM 1.3, that means you do not have DX12 drivers installed to your OS. So while the OS does have DirectX 12, your video drivers do not. Time Spy cannot run if you do not have WDDM 2.0 drivers.

Microsoft is ending all support to Windows 10 1507 (build 10240) on March 26 so after that you either update or you have an unsupported OS as there will be no more security patches for your version.

This is what I downloaded, version 17.2.1 which is the latest WHQL + FM approved driver.

If it refuses to install WDDM 2.0 driver, there is something wrong with your Windows or the AMD driver expliclitly refuses to install it on the Win10 RTM version. I can't say which is the reason here and cannot really help other than "until DXDiag shows WDDM 2.0, Time Spy cannot run".

Windows 10 10240 feels like some joke in bad taste once you experienced the anniversary build. Just get ready to upgrade to the Creators Update with a fresh install once the stable build is released.

Use Winaero Tweaker to get complete control of your Windows configuration, including disabling telemetry, ad platforms, restoring briefcase, selecting dark theme for the settings apps, disabling Windows Defender amongst many other extremely useful features.

I might remember this if I get an M.2 drive. If.
