Windows 10: Keyboard input lag

Hello everyone, a week ago my sister gave me her old work laptop that has a QWERTY spanish keyboard. When i factory reseted the laptop, i chose the azerty option because i'm used to it and my external keyboard is a azerty. However i'm facing a big problem as my keyboard input is very laggy it became very hard to write and impossible to play video games. Here are some things you should know :- This happens with the laptop keyboard and the external keyboard- From time to time, for a few seconds, the nput lag disappears, also after i start my computer it's gone, it comes back like 2-3 minutes a

Keyboard input lag (Logitech K270 wireless keyboard, Windows 10 20H2)

Hi there. I've got yet another Windows 10 problem. lol

This time it's my keyboard. I'm using a Logitech K270 wireless keyboard, on Windows 10 Pro 20H2. I have been experiencing keyboard input lag off and on for a couple months now, and I've searched for possible solutions, but none so far have worked. I was hoping you guys could suggest some fixes.

Here's what I've tried, based on the suggestions I've found on the web:

• Updating the keyboard/dongle's drivers (there are no drivers on Logitechs's site, oddly) and firmware. Nope.
• Swapping USB ports. Nada.
• Unplugging any extraneous USB devices. Zilch.
• Checking the batteries. No joy.

As I was typing this it was lagging here and there. It's a bit disconcerting. Anyway... I don't think I missed anything, but if you need more information or diagnostics, lemme know and I'll upload 'em.

 

Keyboard Input Lag


Hello. Ive just recently started having problems with keyboard input lag. Meaning, I will type and it will not register until a full second after I hit the key. I have re-installed java multiple times. Scanned my computer for harmfull virises, programs. Ive switched keyboards, and the problem still occurs. I am at a standstill at what to do and would really appreciate some help. Thank You!

 

Keyboard Input Lag During Computer Start


Has anyone had trouble with keyboard input lag when the computer starts? I've tried typing in Chrome and Sticky Notes right after the computer logs in and there is heavy lag between keystroke and the character being displayed. This problem only exists the first 10-20 seconds or so after login and also while i'm alt-tabbed out of GTA V. Afterwards, keyboard input behaves normally. On another computer (not with me at the moment) also running an SSD, I don't remember there being any keyboard input lag in Chrome right after the computer starts.

I've recently done a fresh install of Windows 10 but in my previous Win 8.1 setup, this issue was also present.

Here are my system specs:
Windows 10
Asus Sabertooth z77
i7-3770k
Samsung 850 Evo
16gb Vengeance RAM @ 1600 mhz
GTX 780ti
