Visual issues (tearing, etc...)

I have been playing around with an elevated 3rd person camera, and I've noticed that when up top there are several funny visual issues looking down. Specifically, the footprint decals and shadows flicker pretty badly, and some models 'tear' when the camera is moved around (I use the keyboard to slide the camera around (x,y). Also, it seems worse under D3D that OpenGL, but is present in both. So, does anyone know what the cause is. Or, how to fix it?? :) Thanks.

I think the flickering footprints would be the Z-Buffer. If the Z-Buffer isn't detailed enough and objects are close together (The ground and the footprint are really close together) then it will flicker due to rounding errors.

Well, it seems that increasing the FOV (it was really small) has taken care of the problem (though the shadow still flickers occasionally, it isn't very bad). Thanks.

'Tearing' is just happening because you aren't locking your frame rate to vsync. There should be an option in your video drivers to do this.

Flickering is a Z-buffer issue. As mentioned, the best way to correct it is to increase color depth, which increases the precision of the z buffer. Failing that, you can move the near and far clip planes closer together.'Tearing' is just happening because you aren't locking your frame rate to vsync.
