When a ship has been damaged (even slightly) and has moved a distance away from me, the textures on sizeable areas of the ship 'shimmer'. They're either shimmering black or with the damage textures, but I can't really tell because it's too far away.
The BC gfx settings give me multiple options for display device; 'Nvidia geforce gtx 260' and 'T&L Nvidia geforce gtx 260' (I use 'T&L Nvidia geforce gtx 260' because it runs smoother). If I swap from one to the other and back again while in-game, the shimmering goes away. But it returns the next time I run BC.
I've checked on a fresh KM install (with the same 'T&L Nvidia geforce gtx 260' selected for display device) and the problem is not happening there, so I can only imagine there's something wrong with the install rather than a hardware problem.
Does anyone have any ideas?
