 What you're seeing here is the effect of aggressive RF choke filtering
of the video signal just before the monitor connector on the Righteous
3D (and many other 3Dfx based cards -and- regular 2D cards). The chokes
are used to filter "unwanted" high frequencies from the video signal for
FCC compliance and this is mostly what causes the image to become blurry
at high resolutions/refresh rates. If the chokes are bypassed by
removing them and in their place, solder solid wire jumpers, the image
quality will return to normal. The pass through cable has little to do
with affecting the video quality (blurriness) but alot to do with
picking up interference from other electronic devices which will cause a
different kind of degradation such as wavy lines or snow.
 My modifications for the R3D and Diamond Viper V330 clear up the video
signal to the quality of my Millennium II's video signal which has the
best image quality I've ever seen.
