So, I have a GTX 760 and an I7 octa-core 4770K 3,50GHz, and my desktop runs Terra Tech quite smoothly at all graphic settings. However; if I have the graphics set to anything more than simple it will start flashing random "shadows" around the map. It goes away when I set the graphics back to simple, even though I have 40FPS+ when having graphics set to fantastic. I have no other problems in other games, only Terra Tech, so I doubt it's a hardware issue. These "shadows" occur often in hills and flash several times a second and does not go away unless I set the graphics back to simple. They are a little bit more transparent than normal shadows, and can occur several places simontaniously.
