What feature level is the 29 285 supposed to have? GPU-z and dxdiag are reporting 11.1, is this correct?

API Overhead 1st launch driver for 8.1, no DX12. 2nd 15.200.1040.0 Tonga code path. 3rd 15.200.1040.0 Tahiti code path. 4th 15.200.1023.10 Fiji code path. (quite best in everything. On DX11 just a little bit) 5th 15.200.1046.0 (15.7 WHQL) 6th 15.200.1055.0 (original does not have code path for Fiji, but inf config added by asder00. So not fully Fiji aware.); While it does best in draw calls, its gaming performance is under 1023.10/1046.0 and crashes firefox in case you have game open and then open new tab. 7th 15.200.1046.2 Seems like it has improvements from 15.200.1055 but does not cause crashes. 8th 15.200.1062.1002 (15.7.1 W10 release driver) Overhead test is basically same for last 3 drivers listed.

Not here. 1046.2 is still the leader in the API overhead test by quite a bit. http://forums.guru3d.com/showpost.php?p=5131558&postcount=1058

Margin of error... 3~4.5% . If you want to see something funny, what's not margin of error, go to registry find there dword "StutterMode", change its value to 2001 (decimal 8193). Kill mom & ccc, restart ccc & mom by entering catalyst on desktop, retest A pi overhead for all APIs.

All that did was prevent my display from being shown and caused bootloops. Thanks 🙂

When I run dx12 api overhead test I get Direct x12 -API not supported Anybody ? DDU used in safe mode and then 15.7.1 installed (win10)

Default for Fury is 2002 (on left), 2001 on right: http://www.3dmark.com/compare/aot/48482/aot/48536 With previous drivers DX12 went even over 15M and mantle did catch up. For older cards there was max StutterMode 1 or 2 based on card. That 200x code path is apparently not for older cards.

Latest 3DMark?

Yeh all other benchmarks are v1.1 but api test is v1.0 System gui version v4.36.512.0 gui version v1.5893(64bit) also : Futuremark 3DMark Professional 1.5.893

You need to update to a later 3DMark.

Is this newer/better than the latest Win10 driver that came over win update?

What version are you currently on ?

What's new in 3DMark 1.5.915 This is a minor update. Benchmark scores are unaffected. Note that while Windows 10 is in development there may be unforeseeable compatibility problems with some hardware configurations. Improved SystemInfo module updated to 4.39 for improved detection of upcoming hardware from AMD and Intel. Compatibility API Overhead feature test updated to work with Windows 10 Technical Preview build 10130. Known issues AMD Catalyst Driver 15.200.1023.5 for Windows 10 has an issue that prevents the DirectX 12 API Overhead test from working on Radeon R9 280, Radeon HD 79xx series, and Radeon HD 78xx series graphics cards. We expect AMD to fix the issue with its next driver update. Intel HD Graphics Driver 10.18.15.4204 for Windows 10 does not appear to have working full screen DirectX 12 support. We are investigating this issue for a future update.

I don't think so. I went back to 1046.2
