motion blur

sounds a bit like the same issue the last tenebrae had with postprocessing effects (also affected the entire screen) i newer quite figured out what goes wrong with it :S

Looks like normal behaviour for this kind of effect. You're taking 8 samples, so for further objects those 8 samples will be from parts of them that are further apart in world-space, and so they'll blur more. It's likely also frame-rate dependent as it updates the blur every frame, so it will look very different running at 20 fps to how it would look at 200 fps.

One thing I would do with this kind of effect is fold the polyblend into it too - that way, if a polyblend is active, you get it (almost) for free rather than having to do another fillrate-intensive pass over the full screen.

motion blur with polyblend (copy screen and draw up of frame) look so ugly
