what i mean by question 2 is : when i run rs7 for example i can see blackboards, and when i move my head , the screen just follow my head , its not like i am in the game . its like just the screen is following my head .
+ when i turn my head 180degree , i still see the same view ,just the screen is following my head with the same view . i dont see what is in the back .
like if i am seeing a house in front of me , and turned my head 180 , i still see the house , i dont see what is in the back .
my English is not good enough to explain it better xD
about Q3 : Does it have to do something with the quality or something ?
