I'm playing Warcraft on a monster PC and a crappy laptop. The reason for the laptop is that it allows me to play downstairs (in the living room) and do simple things (some quests, rep farming, daily HC, alt leveling) while keeping an eye out for kid/wife.
Laptop in question is:
Pentium 1600 mhz
Windows XP
512 MB...
Radeon Mobility 9000, 32MB
332 MB left of the 40G hard-drive and it's only OS, some small tools, AV, anti spyware stuff and of course WoW + addons.
I can play the game with some limitations: old world is extremely playable except for rush hours in Orgrimmar, WOTLK heroic dungeons are doable, Dalaran is a no-go area.
This is not a simple does this laptop play WoW question, but more a what do other people use to maximize the use of their crappy laptop/PC hardware, network hardware, provider and/or OS.
I'm currently using Game Booster which closes down unused Windows processes so my CPU has less load to work with.
So, do you know/use any (gaming) performance boosters?
