Ok, I quickly tried this (remove 'virtual', compiled, removed old
gmon.out file, played new game, ran same command ("gprof -q
--min-count=10 glob2 ~/gmon.out > ~/profile.txt"), and here are the
new results:
Hm, we'd better call that 'inconclusive'.
The time spent in Sprite::getW increased to 11%, but the total run time
seems to have decreased by 3 seconds.
That so much time is spent there is probably a cache thing - getW is the
first thing done to a sprite image when we're about to draw it, so that
is the point where the image is loaded into the cache.
I assume your platform is quite different from mine, since your numbers
are so different; or perhaps we are talking about a high-resolution
screen as well? (showing more squares at a time) :-)
