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 :
