That happens when the game (my Client ?) decides to draw Hills (for example) lower than they should be, it fixes usually if you move closer and the Mechs are now hidden behind the hilltops in cover.
It seems i can shot that Mechs as long they stand in the air (at least from the visual feedback).
This happens with my old ATI HD 6950 as well with the new ATI R9 280X.
PS: And fix the Mechlab that it runs in a GPU low power mode bcs its not necessary to burn energy for that pls.
