Actually I'm playing dead space 2 and yes I have it on XBOX I also have it on pc , however, My Xbox is currently out of commission so I'm playing the PC version. Action by default on Xbox is "X", and the PC version by default is "E". When "E" pops on the screen your supposed to press it as fast as you can, but I assume you know that. I also had the same problem with BF3 so you were correct to assume that. I'm just wordering if the reason for my problem is a lack of performance, or something else because I have integrated graphics. My PC runs a Nvidia Geforce graphics card. I'm thinking I just need an upgrade, but for any other part in the game when I used the action button the game performed perfectly. So I am still trying to figure out my issue.
