Bad aim is frustrating, but most players who struggle with it are making the same fixable mistakes. The good news is that aim is a learnable skill with clear foundations – sensitivity settings, crosshair placement, physical setup and deliberate practice. The bad news is that genuine improvement takes weeks, not a single session in an aim trainer. This guide is for players who want to understand why their aim is inconsistent and build a proper foundation rather than just grinding games and hoping for progress.
Why Sensitivity Settings Matter More Than You Think
The single most common mistake new FPS players make is running their sensitivity too high. High sensitivity feels responsive and is tempting when you are first starting out, but it makes fine adjustments nearly impossible. Your hand trembles slightly when you move a mouse – at high sensitivity, that tremor becomes visible aim deviation. At lower sensitivity, it disappears into noise.
The relevant metric is eDPI (effective dots per inch), which combines your mouse DPI and your in-game sensitivity into a single number you can compare across games and players.
eDPI = Mouse DPI x In-Game Sensitivity
For example: a mouse set to 800 DPI with an in-game sensitivity of 1.5 gives an eDPI of 1200.
Professional FPS players in games like CS2 and Valorant typically play between 200 and 800 eDPI. The median is around 400. This does not mean you need to play at exactly those values, but if your eDPI is above 1500 and you are struggling with consistency, sensitivity is almost certainly a factor.
How to find your sensitivity: Start by setting your DPI to 800 (standard for most gaming mice) and your in-game sensitivity so that a full swipe of your mouse pad moves you 180 degrees in-game. Play with this for a week before adjusting. The instinct to crank sensitivity back up is strong early on – resist it. Your muscle memory needs time to adapt.
Mouse Pad Size and Physical Setup
A large mouse pad is not a luxury, it is a functional requirement if you play at lower sensitivity. If your eDPI is 400 and your mouse pad is 20cm wide, you will constantly be running out of space and lifting the mouse to reset – this interrupts tracking completely.
A 3XL pad (around 90-120cm wide) is ideal for low-sensitivity players. Even an XL pad (45cm wide) is a significant improvement over a standard desk mat. Cloth pads offer more control; hard pads offer more speed. Control surfaces suit lower sensitivity; speed surfaces suit higher sensitivity. Start with cloth if you are unsure.
Your mouse should sit comfortably in your hand without your fingers gripping it tightly. Tension in your hand transfers into your aim. Aim with your whole arm for large movements and use wrist for fine adjustments – pure wrist aiming limits your range of motion and consistency.
Crosshair Placement
Crosshair placement is arguably more impactful than raw mechanical aim and requires no physical skill – it is entirely a mental habit.
The principle is simple: keep your crosshair at head height, positioned where an opponent’s head would be as they come into view. If you are pre-aiming a doorway, your crosshair should be head height at the edge of that door. If you are holding an angle, it should be where the enemy’s head will appear, not pointed at the ground or ceiling.
Players who do this well appear to have faster reflexes. They do not – they are simply moving their crosshair a small distance rather than a large one. A player with average mechanical aim but excellent crosshair placement will consistently outperform a player with excellent mechanical aim and poor placement.
To practise this, play through a map slowly in a private lobby or against bots. Walk around and consciously adjust your crosshair to head height at every corner and door. It becomes automatic within a few weeks.
Flick Shots vs Tracking
These are two distinct mechanical skills and most games require both.
Tracking is keeping your crosshair on a moving target continuously. It is relevant when targets are moving predictably (strafing in the open, moving in a straight line) and is the dominant skill in games like Apex Legends or Overwatch.
Flick shots are fast corrections to place your crosshair on a target quickly. They are more relevant in games like CS2 where movement is slower and peek duels are common.
Most players have a natural preference for one or the other. In aim trainers, work the one you find harder. Pure tracking practice (following a moving sphere without stopping) builds the muscle memory for Apex-style fights. Static clicking (clicking targets before they disappear) builds the precision for CS2-style duels.
Aim Trainers: Aimlabs and KovaaK’s
Aimlabs is free on Steam and has the lower barrier to entry. It includes a wide variety of tasks, integrates with popular games to approximate their sensitivity, and gives performance metrics over time. For most players, Aimlabs is the right starting point.
KovaaK’s costs around £6-7 on Steam and has a more extensive scenario library, including community-created content closely replicating specific games. It is more popular with serious players who want to follow a structured routine. The Voltaic benchmarking system (community-run, free) gives you a standardised skill ranking and a recommended playlist based on your current level.
Neither tool will substitute for in-game practice, but 15-20 minutes in an aim trainer before a gaming session is a well-documented warm-up method used at the professional level. Use them to warm up, not as a replacement for playing the actual game.
In-Game Settings That Affect Aim
Several settings directly impact how your aim behaves and should be configured correctly.
Field of View (FoV): A higher FoV (100-110 in most shooters) gives you more peripheral vision and makes targets appear slightly smaller. A lower FoV (80-90) makes targets appear larger but reduces peripheral awareness. Most competitive players use 100-103. Use whatever feels natural, but be aware that changing FoV changes your effective sensitivity.
Motion Blur: Turn it off. All of it. Camera motion blur, object motion blur, all of it. Motion blur creates visual noise that makes tracking moving targets harder. There is no competitive reason to have it enabled.
Mouse Acceleration (Windows): As mentioned in our PC setup guide, turn this off in Windows. Go to Mouse Settings, then Additional Mouse Settings, then Pointer Options, and uncheck “Enhance pointer precision.” Mouse acceleration means your cursor moves a different distance depending on how fast you move the mouse, which makes consistent muscle memory impossible to build.
Raw Input: In most modern FPS games, there is a “Raw Input” or “Raw Mouse Input” option. Turn it on. This bypasses Windows cursor settings entirely and reads directly from the mouse, giving you the most consistent possible input.
Practice Routines That Actually Work
The most common mistake in aim training is unstructured grinding. Playing ranked for four hours is not the same as deliberate practice, even though it feels productive.
A routine that works:
- Warm-up (15 minutes in Aimlabs or KovaaK’s): Focus on the skill you are weakest at. If tracking is your weakness, do tracking scenarios. Do not just play the scenarios you are already good at.
- Active in-game practice (30-60 minutes in a structured way): Deathmatch servers, or the game’s built-in training mode. Focus on applying crosshair placement consciously, not winning.
- Normal play: After warm-up and deliberate practice, play your actual matches. You will find that the deliberate practice transfers faster than pure match play alone.
Consistency matters more than volume. Twenty minutes every day is better than three hours once a week. Muscle memory is built through repetition over time, not through single marathon sessions.
The Honest Timeline
Measurable improvement in aim takes four to eight weeks of consistent practice. In the first two weeks, things may feel worse as your brain adjusts to new sensitivity settings and habits. This is normal. Do not switch your settings every few days because something feels uncomfortable – give each change at least a week before evaluating it.
The players who improve fastest are those who accept they will perform worse in the short term while building better foundations. Change one variable at a time, track your performance metrics in an aim trainer, and trust the process. The mechanical ceiling in most FPS games is not as high as it appears – consistent crosshair placement and a solid sensitivity will get you surprisingly far.
