uh for one i dont use vsync so herp derp durrr also Bad Company 2 dosent tear that badly at all the texture flicker from having AA on is much more distracting. so you can shit can vsync limiting my frame rate genius.
and i dont live in a trailer I live in a 3 bedroom 1 bath home on US Route 1. with a Gambrel Garage and a secondary 600 square foot workshop. Although it would be nice to take down
the old workshop put a trailer there for my white trailer trash buddies to live in. then i could collect rent and make some extra cash....
my K/D and score per round tends to be Optimal around 90fps or better at anything below 60 i do terrible, but at 60 im still not playing my best. 90-100fps is my sweet spot. and tearing only really bothers me in RPGs. namely Oblivion Fallout 3 and New Vegas the gamebryo engine suffers from tearing to an extreme, where as Frostbite engine it dosent phase me at all.
but Vsync does remove tearing it can cause input lag in some titles, Dead Space in one where its extremely noticeable in the menus etc. at least when it was first released no idea if they fix that or not. for some people 30fps is enough others its 60fps for me it depends on the game title
in RTS games 30fps is fine in RPGs i like a solid 60fps but for First Person shooters i want the highest possible frame rate i can get.
