If you’ve ever felt like you pressed the trigger in Valorant, but the shot registered just a bit late, you’ve felt input lag. It’s one of those hidden parts of gaming most folks don’t think about until they notice their gameplay feels off. At Mamija Gaming, we’ve swapped enough monitors and mice to know how even a small bit of input lag can change how a game feels.
Understanding Input Lag
Input lag in gaming is the small delay between you clicking your mouse or tapping a key and seeing that action happen on your screen. It’s not the same as internet lag, which is when your connection stutters, and it’s not the same as having low FPS. This is purely about how fast your monitor and setup respond to you.
I noticed this the first time I switched from a budget 60Hz office monitor to a 144Hz gaming monitor while testing for a CS2 review. Suddenly, shots landed closer to when I clicked, and tracking felt natural instead of fighting the cursor. Before that, I blamed my reactions, but it was input lag making me feel slow.
As one user on Reddit put it:
“Switched from a TV to a 144Hz monitor, and it’s like I got a speed boost I didn’t know I needed.” – u/FPSDad
What Causes Input Lag in Gaming?
Your monitor is usually the biggest factor. Some screens add extra image processing, like dynamic contrast or motion smoothing, that can make games look nice but add milliseconds of delay between your input and the action. Those milliseconds add up in fast games.
Wireless peripherals can add a touch of delay too. It’s not always noticeable in RPGs, but in shooters, you feel that disconnect, especially in tight fights. I tested a wireless mouse while reviewing a CRUA monitor, and while it felt fine in Genshin Impact, in Apex Legends, my flick shots felt muddy.
V-Sync can also add input lag by buffering frames to prevent screen tearing. If your system isn’t consistently pushing the refresh rate of your monitor, enabling V-Sync can make your inputs feel sluggish.
How Input Lag Affects Different Games
In FPS games like CS2 or Valorant, input lag can mean you’re a fraction late on your shots, and in tight moments, that fraction decides whether you win or lose a duel. One player in our community described it well:
“I thought I was just bad, but switching to a lower input lag monitor made my shots feel in sync with my hand. It doesn’t make you Shroud, but it helps.” – Mamija Gaming Discord user
In fighting games, input lag can mess with your combos, and in racing games, it can throw off your turns, making your car feel like it’s reacting with a slight delay.
Even in slower games, like RPGs, you’ll notice camera panning and menu navigation feel more fluid when input lag is low. It’s the kind of upgrade that makes your gaming setup feel premium without spending a fortune.
How to Measure Input Lag Without Fancy Tools
You don’t need lab gear to sense input lag. If you move from a 60Hz monitor to a 144Hz or 165Hz screen, you’ll feel how snappy things become. Your aim tracks your mouse naturally, and you don’t feel like there’s a rubber band between your hand and your crosshair.
Some folks use high-speed cameras to measure exact milliseconds of lag, but in real-world gaming, your hands and eyes are enough to tell you if your setup is holding you back.
How to Reduce Input Lag in Gaming
At Mamija Gaming, we’ve helped players tune their setups to reduce input lag without buying a $1000 monitor. Here’s what’s worked:
- Use Game Mode on your monitor to disable extra processing.
- Turn off V-Sync if your GPU can handle the game without tearing.
- Keep your FPS close to your monitor’s refresh rate.
- Use a wired mouse for shooters if you’re noticing slight delays.
- Avoid maxing out graphics if it tanks your FPS during heavy fights.
I remember testing a wired vs. wireless mouse while reviewing a 165Hz monitor, and the wired option just felt tighter in Apex Legends. It’s small, but in intense games, every millisecond matters.
Refresh Rate, Response Time, and Input Lag
These terms get tossed around a lot, so let’s clear them up:
- Refresh Rate (Hz): how many frames your monitor can display per second.
- Response Time: how fast a pixel changes color.
- Input Lag: the delay between your input and the on-screen action.
A higher refresh rate reduces perceived input lag by updating the screen more frequently. However, a 240Hz monitor with heavy image processing can still have higher input lag than a 144Hz gaming monitor set up properly.
What Input Lag is Acceptable in Gaming?
For most gamers, under 20ms of input lag is acceptable, and you’ll rarely notice.
For competitive shooters, aiming for under 10ms helps you stay in sync with your actions.
One user on Reddit described it well:
“You don’t realize how bad your setup is until you try low input lag gaming. Once you do, there’s no going back.” – u/LowLagHunter
Real-World Testing
During one of our monitor reviews, I tested CS2 on a 60Hz monitor with V-Sync enabled, then switched to a 144Hz screen with Game Mode on. The change was immediate. Aiming felt sharp, and my shots connected closer to when I actually clicked, rather than feeling that slight delay.
Even in slower games like Baldur’s Gate 3, panning the camera and moving between menus felt smoother, making the game more enjoyable during long sessions.
Why Input Lag Matters
Input lag in gaming isn’t just a niche concern for “hardcore” players. It affects how your games feel, from shooters to RPGs, and improving it can make gaming more fun.
If you’re wondering how to reduce input lag in gaming, the best steps are:
- Use a gaming monitor with low input lag.
- Enable Game Mode to reduce processing delays.
- Match your FPS to your refresh rate and avoid V-Sync if possible.
- Use wired peripherals for faster response.

Final Thoughts
So, what is input lag in gaming? It’s the small but impactful delay between your actions and what you see on screen. Lowering it makes your games feel snappier and more responsive, whether you’re casually gaming or trying to climb ranks in CS2.
What input lag is acceptable in gaming? Under 20ms is fine for most, under 10ms is better for competitive play.
Don’t let input lag hold back your gaming experience. Small upgrades like a better monitor or tweaking your settings can make a noticeable difference.
