need game help

hi im in crossfire and when i play i suck balls if always first to get killed in ghost mode and other modes is their any tips and tricks to be a pro or better
2. in elimnation mode what guns do you guys rush to pick up and why that gun.
3. also how to fix lag nnnooooo not lag i mean make fps higher i disballed replay and graphics low and took off explorer.exe while i play their just tiny lag i need help

1. In ghost mode / GM - On Global Risk side you need good headphones to hear the ghost or if your on Black List side you need to learn to bunny hop / bhop.. look it up on Youtube if you don't know how and try getting a better knife weapon as in (Kukri,Axe and Shovel etc.).

2. The guns you mainly wanna go for, well if your a sniper I would try to get awm real fast.. but if you rifle I would suggest K-2, M4A1, or AK-47 and also try to get Desert Eagle comes in handy.

3. I am not sure.. I don't FPS lag on Crossfire.. sorry
