RX470 screen tearing in Win7

Issue: annoying glitch - screen tearing - approximately 2/5th from bottom of screen while showing 1080p@60Hz.

Appears regardless of software (VLC, BeyondTV, YouTube).

Appears on LCD video projector and LCD TV/Monitor.

 

Radeon RX470, 4 GiB

AMD FX-8320 8 Core CPU

16 GB DDR3

ASROCK 970 EXTREME3 MB

Crimson ReLive 17.30.1041-170720a-316469C

 

TEARING video on 1080p Projector & UHDTV only became noticeable after reverting from Win10 => Win7.

This leads me to assume it is a software / driver incompatibility issue, and not related to hardware.

And since it was a NEW install with up to date drivers, there should be no issue with old drivers.

 

When I tried to make a screen capture (at 30 fps), the captured image showed no tearing.

 

Global Settings:

Anti-aliasing Mode - Use application settings

Anti-aliasing Method - Mutlisampling

Morphological Filtering - OFF

Anisotropic Filter Mode - Use application settings

Texture Filtering Quality - Standard

Surface Format Optimization - ON

Wait for Vertical Refresh - Always ON

OpenGL Triple Buffering - ON

Shader Cache - AMD optimized

Tessellation mode - use application settings

 

What is most frustrating - my low budget Celeron G1840 with integrated graphics can display 1080p@60Hz with NO TEARING.

 

P.S. - is there documentation / manual for Catalyst / Crimson that goes into detail on what each setting is and does?
