What are some methods I could use to improve my aim in FPS games
user
Here is a list of ways you can improve your aim in FPS video games:

1. Find a mouse or controller sensitivity you're comfortable with and stick to it.
One of the most important aspects of aiming is muscle memory. Sticking to one sensitivity setting will give you a stable environment to develop your skills. Consistency is king.

2. Consider lowering your Field Of View (FOV) if you play on a very high setting.
While a high FOV will allow you to see more of your surroundings, it will also make targets appear smaller. Targets will be easier to hit with a smaller FOV, but at the cost of lowering your peripheral vision. You will have to decide which of these factors are more important to you. Similar to your sensitivity, you should find a setting you're comfortable with and stick to it. 

3. Use training modes, private matches, and bots to your advantage.
Many games include the ability to play against bots offline. Doing so may help reduce distractions - allowing you to focus on your aim.
Additionally, you can load into a map on your own to practice. Try finding two objects, such as a stop sign and a fire hydrant, and aim back and forth between them. Slowly increase the speed at which you switch between these targets until you're no longer accurate, then start again.

4. If using a keyboard and mouse, try aiming with your whole arm, not just your wrist.
While small movements with your wrist may make sense for minor adjustments, you can take advantage of additional muscles by using your whole arm to aim. Doing so will reduce strain by dividing the work between your muscles and allow you to make larger, more fluid adjustments easily.

5. Identify if you're better at tracking or flicking and choose loadouts that fit your style.
Tracking is being able to consistently follow a target as they move, whereas flicking is being able to quickly snap to a position a target is currently at. Players who are better at tracking may find they are more effective with weapons that require multiple rapid shots to eliminate a target, such as assault rifles, smgs, etc. Players who are better at flicking may find they are more effective with weapons that only require one shot to eliminate a target but fire slower, such as shotguns, sniper rifles, etc.

As always, ensure to take breaks when playing video games for long periods of time. Doing so will refresh your body and mind, improve your health, and prevent you from getting tilted.
