weird texture distortion

I just added a new model to the game and suddenly all of its textures are behaving really weird. They are blurring out and and flickering when I move (it can be seen a little when the camera is static also).

This is the first time I'm seeing anything like that - I thought this was a video card issue, but then it doesn't make sense that it only appears now. Could this be caused by the model? Or maybe it's just the 'bumped specular' render issue (I've never really used it much before)
