Spent the last few hours researching and messing about. All of the below has been done on max settings (including tessellation), just changing the resolution.
- Switching Tesselation in CCC from AMD optimised to Application controlled seems to control the massive artifact I was getting
- Was still getting massive artifact at 1900x1200. Strangely, if I open Heaven in 1900x1200 there is loads of artifact and flickering, yet if I start in 1680x1050 and then switch resolution in program to 1900x1200 while keeping other settings the same it runs fine.
- At 1680x1080 I was still getting artifact in top left corner (blue blocks intermittently) on benchmarking. This was sorted by turning on 'AMD Overdrive' in CCC (even without changing any of the settings it unlocks).
This is on stock clock/mem/voltage [which is 1050/1250/1.168] at 1680x1050:
This is on stock clock/mem/voltage at 1900x1200:
This is on 1175/1450/stock voltage at 1680x1050:
Then the 1175/1450/stock voltage at 1900x1200:
Temps have not gone above 64C. Also, 3D Mark 11 hasn't caused probs on their benchmark.
Does the above seem normal? Have had a good google, but love to learn.
