Freakgs: This has always been a big issue with AITD. I remember having the exact same problem when I first played the game on a 486 dx2 (good old times). There's even a scene in AITD3 where you are absolutely required to run, if you fail you die. So that specific scene was always frustrating.
Yeah, I understand you... I suffer on this Scene too. on my old Windows 95 edition "Alone in the dark 3 Ghost in town" I played on a powerfull....PENTIUM 2 (LOL). it was frutrating too. because I only can run when I lucky. It was relative more dificult because you can`t control the speed on windows... Thanks to god on DOS was MOSLOW (XD).
well and for the problem Why do not try to change some values on your .conf archive. try this.
[dosbox]
memsize=32
[cpu]
core=auto
cycles=max
cycleup=1000
cycledown=1000
Relatively The speed of your procesor must be increse. and the movement must be really smooth. in theory the control answer will improve.
NOTE: This config values I use for games like doom and quake (on 320x200 of course). Tomorrow I will download again my AITD and test diferent configurations on it.
Good luck.
