High quality MSAA on alpha-tested objects
 |
 |
DirectX 10 One can see pretty wide seams around the silhouettes of leaves that jitter slightly when the camera moves |
DirectX 10.1 Using a shader that sets the proper sample mask in the shader; the silhouette edges are properly anti-aliased; there is no wide seam and no screen door pattern that can introduce jitter |
New ultra quality level for sun shadows

|

|
DirectX 10 Shadows have relatively hard edges, resulting in slightly flickering shadow borders withen players moves through the level
|
DirectX 10.1 New shadow mode that usea a bigger filter footprint for more natural and smoother shadows that don't flicker when the camera moves
|
New min/max shadow map rendering technique for high quality sun shafts
 |
