Bugs is only a small issue, and as I said not really something I'm worried about. Things like FO3 crashing on quad-core machines and having to edit the ini to force the game to only use 2 cores is more what I am talking about. Things like UI's and controls designed specifically for use with a gamepad being copy/pasted into the PC version where folks are using a mouse/keyboard, things like having to hack the exe to allow it to use more that 1/4th the available memory of any baseline system being sold today, these are the types of things folks playing on PC should be concerned about.
Never had those problems before also it could be conflicting like software games are a [censored] to run on windows 7........
