--- Comment #1 from Roderick Colenbrander thunderbird2k@gmx.net 2008-08-21 16:10:28 --- Do you have the Multisampling registry key set? The multisampling effect you see is not directx multisampling but I guess some effect created using shaders or so. Using the dialog you can enable directx multisampling. I can't reproduce this problem right now as the demo doesn't work for me at the moment.
