hello everyone, i'm new to this forum. i have a huge problem and i'm going to try to be very detailed so i can get the best available help from you all. ok, me and my wife has 2 computers and we play second life (not sure if any of you heard of it or not). my problem is, she uses windows vista and i use windows xp. i have 1.5gb's of ram, she has 1gb of ram. my processor is intel 2.4 ghz and she has amd 2.1 ghz. i use the nvidia geforce 6200 and she uses nvidia geforce 6150. i have a dell demension 2400 computer and she has e-machine t5234 computer. when she plays her game, her graphics looks much more fluent and faster than my computer. my graphics and animations are very blocky, choppy, kinda laggy if you understand what i'm trying to say. i've even updated my video card drivers and chip set drivers. how come my gaming performance isnt as good as hers and what can i do to increase my gaming performance before i give in and buy another computer exactly like hers or similar with windows vista?
