âť— My issue (solved):​

I had a super annoying problem while gaming:
👉 When I pressed a key (like A to move left), the character would keep moving more than expected, like the key was held down too long or being dragged.

I thought it was:

  • a broken keyboard
  • bad USB ports
  • driver or system issues (I'm using an ASUS setup)

⚠️ Here’s what I tested:​

  • 3 different keyboards, including ASUS TUF Gaming K3 Gen 2
  • Multiple USB ports
  • Disabled all background apps via msconfig
  • Closed Razer Cortex and other startup apps
  • Made all possible updates (Windows, drivers, BIOS)
âś… Nothing helped... until I uninstalled Razer Synapse 4
➡️ Problem disappeared instantly! No more input delay — keyboard is working perfectly.

🔍 What was actually happening:​

Razer Synapse 4 installs a service called Razer HID that hooks into the HID input layer in Windows.

That means:

Even if you’re using an ASUS, Logitech, or non-Razer keyboard, Synapse still tries to "intercept" and process those key presses.

This causes:

  • input delay
  • keys feeling stuck or slow
  • weird movement in games
  • conflicts with other RGB/control software (like ASUS Armoury Crate, Corsair iCUE, Logitech G Hub, etc.)

âś… Bonus: Mouse macros still worked!​

After uninstalling Synapse 4, the macro I had on my Razer mouse still worked — meaning the mouse saved the macro to its onboard memory.

So:

📌 Final recommendation:​

If you’re getting keyboard lag or weird input behavior, and you have Razer Synapse installed, try this:

  1. Fully uninstall Razer Synapse (especially version 4)
  2. Restart your PC
  3. Try your game again
→ If the problem disappears, it was definitely caused by Synapse.

đź§Ľ Extra tips:​

  • If you only need macros for your Razer mouse:
    • Set them in Synapse → then close Synapse completely from the system tray
  • If you want to use Synapse, use Synapse 3 instead of 4 (it's more stable)
  • If you don’t use Razer peripherals — don’t install Synapse at all
