Re: Stutters, cut off dialogue.
Ok I tried defragging my hard drive, verifying integrity of game cache, disabling cthelper.exe and ati hotkey (although steam says its still running, I don't see it in task manager), still stutters occasionally.
In case this helps, it seems to do it in the same spots. Like in the very first part of the game I get a very tiny stutter as soon as I enter the hallways, and a much more annoying one when I make a right down the hall that has the "specimen cultivation" (I think it is) sign and part of the ceiling explodes.
I played through that part twice, one time with AA disabled and texture filtering at trilinear vs 4x AA and 8X AF and there was no noticeable difference.
