What it does
* Crash cleanup. If a game that uses the 3Dfx card dies unexpectedly, GlideHack tries to shut things down properly so you get your 2D screen back.
* Screen capture. Ordinary screen dump methods don't work with the 3Dfx screen, and not all games provide this functionality on their own. GlideHack lets you capture both snapshots and movies.
* Various tweaks. This includes things like screen gamma manipulation.
Configurations
GlideHack lets you use different settings for different
games. Simply create a configuration document in GlideHack
Setup and save it in the same folder as the game application.
If GlideHack can't find a game-specific configuration,
it uses its defaults (which can be edited with GlideHack
Setup too).
The settings
Override default gamma
Default gamma
Some games don't let you set the output gamma of the
3Dfx card. These let you specify a default gamma value
for those games.
Scale client gamma
Gamma scale factor
Some games do let you set the output gamma, but only
within a limited range. These let you specify a scale
factor for those gamma values in order to widen the
range.
Limit texture unit count
Texture unit count
Not very useful except for Voodoo 2 owners who wish
to see how much worse Unreal looks on a Voodoo 1. :-)
Limit texture RAM
Texture RAM
Some games (such as Carmageddon) get confused by cards
with more than 2 MB of texture memory. These let you
un-confuse them.
Disable triple buffering
Some Voodoo 2 cards don't let you do screen dumps from
the third buffer. Check this if you get nonsense in
one-third of the snapshots or in every third frame
of the movies.
Screen capture gamma
Screen captures from some very dark games (such as
Unreal) may need a bit of brightening to be useful.
Byte swap (Voodoo3)
Voodoo3 cards don't seem do byte swapping in hardware
when reading from the frame buffer. Check this if you
get nonsense colours in Voodoo3 screen captures.
Play sounds
Check this to make the various screen capture operations
play sounds.
Output folder
Lets you specify where screen capture files are saved.
Snapshot keys
Begin movie keys
End movie keys
These buttons bring up a dialog where you can set the
key combination that triggers each function. Any combination
of one to four keys is allowed.
Full size movie
Movies are saved in thousands of colours, uncompressed.
This eats up disk fast, so the spatial dimensions are
scaled by 1/2 in order to save space unless you check
this box.
Precision movie
Frame rate
Divisor
When the precision checkbox isn't checked, frames are
captured as fast as possible. This is actually rather
slow; on my 7600 with a Techworks card, I get about
6 frames per second at 640x480.
When the precision checkbox is checked, the captured
movies have the specified frame rate but are recorded
at a slower speed, as specified by the divisor. For
Myth, you'd set the frame rate to 30 and the divisor
to 8, then start recording with Myth's replay speed
set to 1/8.
If you set the divisor to 0, frames are not recorded
automatically. Instead, one frame is added to the movie
each time you press the snapshot key combination. This
is useful for games that have a replay function with
single-stepping, such as Carmageddon.
