If you got the same problem ( or non stop flickering screen ) try this :
1. Right-click on your desktop and select “Catalyst Control Center.”
2. Select “Preferences” and left-click “Advanced mode.”
3. Click the “Gaming” tab on left.
4. Select “3D Application Settings.”
5. Under the heading “Anti-Aliasing” checkmark “Use application settings” but do not check “Morphological filtering.”
6. Under the heading “Anisotropic filter” checkmark “Use application settings.”
7. Under the heading “Tessellation” checkmark “AMD Optimized.”
8. Under the heading “Catalyst A.I.” move the slider to “Performance.”
9. Under the heading “Wait for vertical sync” move the slider to “On, unless application specifies.”
10. Under the heading “Anti-Aliasing Mode” move the slider to “Performance.”
11. Click “Apply” to save these changes and then start Guild Wars 2.
Once loaded, access the “Graphic Options” window and make the following changes:
1. Change “Refresh Rate” to “60 Hz”
2. Change “Frame Limiter” to “60.”
3. Change “Reflections” to “None.”
4. Change “Render Sampling” to “Native.”
5. Enable “Vertical Sync” at the bottom.
Thanks to gw2 support for this.
It doesn’t really works but greatly reduce the ‘’ display error ’’ ( still unplayable for me, before trying i got this error non-stop and then i got this error every 5 seconds, but heh it’s still an improvement )
I’ll keep this thread updated everytime i’ll have new informations from the gw2 support
