Guus Sliepen 48e8e12b07 Remove 1 second delays. 2011-08-26 14:41:34 +02:00
Guus Sliepen c42ee44271 Don't blit unnecessarily.
During the game, a lot of images were blitted outside the visible area. Also,
addBuffer() was called even when the destination surface was not the screen,
resulting in unnecessary blits in unBuffer().

Guus Sliepen 70d0b13ea2 Use textSurfaces instead of calling drawString() in doInfo().
This increases efficiency significantly. Before, callgrind estimated that 58%
of the CPU time was spent in doInfo(), taking roughly 1.6 kcycles on average
per call. After, only 0.13 kcycles on average per call are used (12x speedup),
and only 14% of the CPU time is spent in doInfo().

Guus Sliepen 9e4ae7e3bd Don't render a textSurface again if nothing has changed. 2011-08-25 13:48:02 +02:00

Guus Sliepen 73c92917e2 Slightly increase intro text scrolling speed.
Scrolling 1/4 pixel per frame results in jerky motion, mostly because 4
times 16 2/3 milliseconds is not a round number. Scrolling 1/3 pixel per
frame results in much smoother scrolling.

Guus Sliepen 5be6a5ec7d Randomize explosion thinktime.
This gives engine trails and explosions a more natural look.

Guus Sliepen 9e32c230be Use float functions on float variables. 2011-08-24 22:43:54 +02:00
Guus Sliepen c14a9e7956 Remove a busy loop when showing an error message. 2011-08-24 22:32:30 +02:00

Guus Sliepen d87a0fcc31 Make sure SetVideoMode() calls are same as in init.cpp. 2011-08-24 21:40:30 +02:00
Guus Sliepen 212b03fa68 Use SDL_DOUBLEBUF in all SDL_SetVideoMode() calls, and don't force 16 bits.
By forcing 16 bits for full screen mode, performs drops dramatically on
displays where SDL has to do conversion.

Guus Sliepen f46bbcef69 Remove more busyloops. 2011-08-24 20:10:21 +02:00

Guus Sliepen fc9dac5195 Strict 60 Hz update rate without busyloops. 2011-08-24 20:02:35 +02:00
Guus Sliepen 0f278a2748 Enable double buffering.
This seems to improve performance (probably because this prevents the
need to lock the screen surface), and might get rid of tearing.

Guus Sliepen 943a4c7bf3 Simplify printing time taken for missions.
This removes a lot of lines while at the same time preventing printing a string
onto itself, which is a bug. Problem was found by cppcheck.
