Patchy Texture HD6850

[Uncl30w3n]

When playing games such as Dead Space, I run everything smoothly on full, but in things like smoke and mist, the textures seem separated and patchy, similar to the separated colors you can see on a 16 bit color desktop. Is there a way this can be fixed, or is this normal?
Thanks

Difficult to say without knowing the game. Doesn't sound right... but at the same time if everything else looks fine its likely not an issue with the GPU....

The only similar issues I've had with pixelation like this were fixed by driver updates
