SS3 ground textures at high settings when SB is enabled
Ground textures in Serious Sam 3 are incorrectly rendered (see the first attachment for a preview).
This only occurs with my RV770, not with my HD5850 (Evergreen).
This only occurs when sb is enabled (which is the default setting).
The first bad commit is :

Worse ground textures at low settings with a more recent commit
I noted that at low settings, a recent commit broken more dramatically the ground textures, see attachment for a preview.
