Digital Integration's
[F-16 Fighting Falcon]
Version 1.2
Patch release: 17 October 1997
DOSWin95 version
---------------------------------------------------------------------------
Feature list:
* Frame rate increase of approximately 15% to 20%!
We have optimised every last shred of F-16 to wring as much speed as
possible from the game running on any Pentium-class processor.
* Feature-rich "check six" view implemented.
The "check six" view aids situational awareness by allowing virtual
pilots to look 180 degrees to the rear. F-16 implements this
realistically as either a 'left-shoulder' or 'right-shoulder' view, in
either 'quick' or 'sticky' mode. Full details are contained in an
accompanying Readme file.
---------------------------------------------------------------------------
Details
Frame rate increase
The program code of F-16 has undergone a collective belt-tightening in an
attempt to augment the general performance of the game across the board.
Several key routines have been re-written in assembly language, with
resulting optimisation better than that obtained from a compiler.
Advantage has also been taken of the pipelining and instruction caching
available to Pentium-class processors. While this gives incrementally
better performance on these processors, it unfortunately means that from
version 1.2 onwards, F-16 will no longer work on the 486 family of
processors.
The cloud system has been updated and now leaves a smaller impact upon
frame rate than it did previously.
We have stated that the overall increase is around 15% to 20% "across the
board". By this we mean that the frame rate increase differs according to
processor type and visual detail settings, however, that percentage always
remains accurate. For example, a Pentium 100 running F-16 with maximum
visual detail may have clocked up 4 or 5 frames per second with the release
version of the game. With v1.2's increase this figure should increase by
approximately 1 frame. However, a higher spec machine which previously
produced a frame rate of, say, 18fps should now see an increase of 3 or 4
frames per second.
To re-iterate, the benefit you see will depend on the framerate your
machine could previously achieve. Whatever happens, though, you will
definitely receive that 15-20% increase.
--------------------------------------
"Check six" viewpoint
After overwhelming requests for this addition to the viewing system, we
offer our own spin on the traditional "check six" viewpoint.
"Check six" functions by allowing pilots to look 180 degrees to the rear
over either their left or right shoulder. From this viewpoint, pilots will
see the dorsal surface of their aircraft and be able to view, with some
obstruction from the ejection seat and tailfin, their entire rear aspect.
In addition to the left and right view, "check six" works in two modes -
Quick and Sticky. Quick view shows the rear aspect only for the length of
time which you depress the view key. Sticky mode locks the rear aspect view
until you switch back to a front view.
Controls for the check-six view are as follows:
* Numbers 9 and 0 (zero) on the typewriter keys select left or right rear
aspect respectively.
These two keys alone activate check-six in Quick mode.
* To use check-six in Sticky mode, hold a Shift key while you tap either 9
or 0 (zero). The view will be locked until you select a new view key.
