Thanks Snow. Yeah it's halo I'm currently tweaking.
Really need to learn the game now. Aim is getting used to the xim ok but I just don't know the maps or danger spots. I'm basically running about looking for opponents and then hoping I can snap my aim to them before they killed me, as invariably they will have seen me first!
Also just started straight into the Swat mode, little extreme but I prefer the game type. Problem being that the playlist is generally comprised of experienced players who play that mode for something different. So they invariably have me spotted before I do them and in Swat you don't get a lot of time to snap your aim to them before you catch a BR round to the head.
I'll keep going and try to refine my config some more!
Start up some multiplayer games on private setting, so that you're the only one on the map the whole time, then get a vehicle and explore around. A good little tip is to go to Bungie.net and look up "heat maps". These maps will indicate where the majority of fighting/dying takes place. You can tell right away, where it's dangerous. They also show commonly used routes by players. All of Halo's map designs were aided by in house playtesting and psychological study of players (playtesters) behaviors and pathfinding, believe it or not. Pretty fancy shmancy and a little on the scary/creepy side (from what I read about it in a Wired article).
Let us know what config you finally come up with after Tweaking and how much your cursor wanders (if it's still bad or minimal).
