i`ve just made a discovery! i have had dead space for over 2 months and have an ATI Radeon HD 4600. the graphics so far are loving amazing and i love how it looks. then find out how loving beast vsync is, so i turn it on.... next thing i know my dead space is running like a loving God Boss. before it was usually choppy and crashed a few times when i fought the final boss on ch 12. now everything moves so smoothly, even on quick events. now i can happily slice down necromorphs with laser percision! gotta love modern day graphics technology.
