erratic mouse/camera movements can be fixed by modifying the APEngine.ini file:
FIX FOR SHUTTERING from OBSIDIAN FORUM:
in APEngine.ini ( C:\Users\<yourname>\Documents\Alpha Protocol\APGame\Config)
change this values to this:
UseBackgroundLevelStreaming=false
OnlyStreamInTextures=true
OneFrameThreadLag=False
Once I modified those values - camera/mouse stuttering disappeared.
The game takes a bit to get use to - reminds me of playing STALKER for the first few hours - sub par graphics, clunky combat, etc. I'd suggest running the training areas a few times until you get a good feel for how combat, stealth, hacking work before taking on your first mission.
I get the feeling they wanted to make a "Splinter Cell Conviction/24" [the show] type of game with RPG elements [stealth, weapon skills, toughness, melee combat, etc]. I chose to start out as a stealthy character - and once I purchased a "stealth suit" + increased my stealthiness [where they always show up on the "radar"] - I can easily sneak up on most enemies and crack their skulls... or put a bullet in their head with my silencer equipped pistol.
Conversation is very similar to the "bioware" rpg choices - depending upon your choice will determine who "loves", likes, dislikes, or outright hates you.
Computer Hacking - it's clunky -but again, once you get use to it - it becomes tolerable. If you don't like it - you can always carry around and use EMP devices.
Eh... it's a clunky game..but like STALKER... it grows on you after you've finished a few missions.
