-"Buffered Gfx" can be set to "off" on slower systems, "Fading" gives
-a nice fading effect when displaying new screens, but unfortunately
-I haven't found a system which is fast enough to display it so far.
-(Maybe this works better on highly accelerated X servers.) Better set
-this to "off" if you have a normal system...
+Forget about the setup options "Buffered Gfx" and "Fading" -- they
+have no effect at the moment and will probably disappear in future
+versions of the game. (Double-buffering is now always activated, because
+systems are fast enough now compared to 1995, when the last version of the
+game was released. Especially soft-scrolling needs the double-buffering.
+About fading from one screen to another with silly effects: Most players
+will probably deactivate it after a few minutes (see also "quick doors").)
+
+Enable "scroll delay" to avoid scrolling at each step, giving you an area
+where you can walk without scrolling until you get near enough to the screen
+border.
+
+Enable "soft scroll" for soft-scrolling. Looks nice, but may need a
+relatively fast graphics card. Systems from 1998 and later should be fast
+enough for enabling soft-scrolling.
+
+Enable "quick doors" if you are unpatient when switching between the
+several game screens where the doors have to be opened or closed. You will
+almost surely enable this if you design your own levels and therefore
+often switch between game and editor screens.
