Forgot to say, I have an i7 950 at around 3 or 3.0 ghz, 8gb ram, win7 64bit, some sata 3 ok fast HD.
My game has about 4661 commands and is split into 20 code files.
An F5 after a clean project:
Wordcount:4661 commands
Elapsed: 10.7 sec. Time: 14:28
If then I press F8:
IncrediBuild skips: TH_AVOCADO_MAYHEM.gbas, BOOT.gbas, DISPLAY_GAME.gbas, HI.gbas, HUDEBUG.gbas, OBJ_CONTROL.gbas, OUTPUT_GAME.gbas, RESET.gbas, SOUND.gbas, ST_AMBIENT.gbas, ST_ARVORE_PATRAO.gbas, ST_AVOCADO_PODRE.gbas, ST_AVOCADOS.gbas, ST_MACACO_PATRAO.gbas, ST_MACACOS.gbas, ST_MORCEGO_PATRAO.gbas, ST_PLAYERS.gbas, ST_POWER.gbas, ST_SCOREBOARD.gbas, ST_WOOD.gbas,
Elapsed: 3.4 sec. Time: 14:30
I think the speed is nice, most probably processor related.
I could do a project tolerating 5x that time at the latest stages without much trouble I guess.
May also put the processors at 3.6 or 3.8 to add a bit speed maybe.
