I feel this will benifit alot of people if they read this so I will repost here.
If your mouse isn't moving smoothly across your screen then this is called stair casing, feeling like it goes in small steps. So I will explain to give you a base knowledge of whats happening on screen, you will be able to better help yourself if you know this info.
Firstly on consoles, game designers make controls set for anolog sticks. The way this works is, when you push say the anolog to the right, it will tell the game i am moving the camera to the right, so then the game asks well how much are you pushing the anolog to the right? in which if you moved it only a little bit it will only move the camera a little, while if you push it right to the edge it moves the camera alot. This works completely different from how a mouse on pc works. A mouse on pc counts how many dots to the right the mouse moved and tracks it to dots on the screen, this is most accurate and probably why you bought this product.
Now what this product does. It tries to make the right anolog move like a mouse. They way it does this basically is when you move the mouse on the aimon to the right, it counts lets say 100 dots, for each one of those dots, it holds the anolog down for a quick moment. The quicker the moment the smaller the motion or "Step" is going to be. Also each game doesn't use the same "Aiming" setup as the other, each has its own tailored way for figuring out how much you want to aim in a certain direction, making for a seperate setting for each game you play, generally. Now I could tell you what works for me but each player has different tastes, mine won't be the same as yours so I will recommend you do the following:
1. get the most current driver and follow the directions on this site to install it and set up your aimon to the comp.
2. update your setup software, again follow the websites instructions on how to pair your aimon to the computer.
3. upgrade the firmware, there will be a list of several games that has different aiming setting for each. What these do is it gets the aimon to play nice to the specific difference of each game. Also there will be a STD setting which is the baseline that works with all, it won't be optimized for a specific game but is a great start to calibrating. Start with STD and then try the games particular firmware, like Black Ops for example will have a specific firmware. You can use other firmware with other games, and in some cases may improve the quality of aim, think of yourself as a pioneer exploring new ground. You are one of few testing this product and not even the guys who made it have one right answer for using it, you've got to find it for yourself.
4. after selecting your firmware check the RF slide on the setup software, this will find a spot on the 2.4 ghz band that isnt going to mess with something else in your house, if you have wifi, wireless phones, cell phones , so on they all run on this band and cause intereference with the device. Finding an open space will ensure that you won't get drops from your reciever to the controller.
5. get a usb extender, I know this is a wireless device and should be capable to work from a distance from the reciever but time and time again proven on these forums if you have it right beside the device, you will not fall victim to dropped signals, were all of a sudden your mouse just stops working and the light on the usb dongle stops lighting up.
6. In game in your particular game, set the sensitivity setting for aiming to the highest possible, what this does is tells the game to count more dots for a smaller length of being pushed to the side. then on your mouse press and hold the "F" key above the O,X,Square, and triangle button. While pressing this scroll up on the scroll wheel, your character should be turning in a circle, and the more you press the scroll wheel up the quicker your character turns. After these two steps start dialing down the quickness to your liking.
Also make sure you look down iron sights aswell, because if you only account for the hip fire smoothness it will be different then what the iron sight smoothness. This is because designers of the game made the iron sight setting push the anolog alot slower, so even it you have smooth setting for your hip fire, it may be staircasing while aiming down. You wont find something perfect but something in between.
After all of this, keep repeating the process and mess around with the settings like :
A: Higher in game sensitivity
> Lower in game sensitivity
B: Higher Mouse Sensitivity
> Lower mouse Sensetivity
C: Game Specific firmware
> Some Other Game Firmware
This combonation of settings you should find yourself something you like, take the time to mess aroud with it, this product isn't plug and play. This is for hardcore gamers who want to play like they do on PC. if you can't be bothered with this process then don't buy the product.
