I use these video settings (see screenshot number 3) to have no problems with the "missing textures" bug
The problem seems to be resolved when i update my radeon hd drivers to the final version and turning off completely the mipmapping (see screenshot number 2) . BUT i want to play with mipmapping turned ON , because the trees at distance look very awful without the mipmapping . So please , as soon as possible , make an update resolving this problem . Thanks .
Ok , thanks for the fast response .
