Please report in appropriate bug-reporting threads.

You may try playing with different Aniso, AA, texture and mipmap settings in ATI Tray Tools (replacement for Control Center). I have both set to Application Controlled though.

Does any owner of nVidia card has this bug?

Thanks Ataros, I already reported in the bug-threads but I didn't get an answer, so I thought I was the only one to have it.

EDIT:
I just changed the Anisotropic filter to Application Controlled and the lines disappeared finally.... thanks again

I've occasionally seen those lines outlining a box, but not quite as distinct as in your screenshot. Same graphics card. I'll try that change, thanks.

The map on this game is made out by many squares and what you experience is the boder of one of this squares visible because a glitch in the video renderinng.
