Just a teaser of the motion blur in Sylphis3D. As you can see this is not a fake-blend-over-the-last-frame type of motion blur.
This is the real thing! It is independent of the frame rate. You can actually set the simulated shutter speed you like. You can have shutter speeds bigger or lower that the frame time, only the shutter speed affects the amount of motion blur.
You can also set shutter speeds per object. You can control the motion blur amount per object, so that other object blur more and others less.
This is a simulated 24 sub-frame motion blur and it runs on any video card that supports GLSL shaders.
