nahimic2svc32.exe causing major keyboard lag

This took me forever to work out but by process of elimination I've finally found out that nahimic2svc32.exe is the cause.  I will get between 10-20 seconds of delay between pressing a key and the action happening on screen.  This so far has only happened while playing Player Unknown Battle Grounds (PUBG) however it persists after exiting the game so no matter what I do until I restart or end the process there's massive lag between pressing a key and the response being registered.

Using the MSI GT73VR 6RE with your latest application and the latest realtek driver.

The problem is interesting, I'll need more information: 
- Current OS
- Realtek and Nahimic version
- Reshade or no?
- only on PUBG? 

MSI GT72VR 6RE same here.

Someone suggested that my problem was definitely the nahimic drivers.


You guys said no, that it was because I force quit overwatch, but then I said that no, that wasn't always the case.  Sometimes I can just exit it and still get the nahimic driver crash on reboot.

But now I realize that Microsoft IME sometimes hangs really badly... and that's a key thing too...

Win 10 pro 64 bit
Nahimic 2 - 2.5.24
Realtek - R2.82
No reshade
so far only happens when using PUBG however 95% of time I'm playing is this.

Win 10 Pro

Nahimic 2.5.29 + realtek drivers


This was happening to me some time ago - found a solution with using older Nahimic. AND IT SOLVED THE PROBLEM - i didn't do anything else!
Now I reinstalled my pc and downloaded newest Nahimic -> happened again while playing DotA 2 and Overwatch, same as before. I am not using any other sw while playing.

Never happened with anything else, but games. ... Now I am going to find some older Nahimic version.. :( If I remember it right, it has to be pre "+" version...

Here is the link for an older version of Nahimic, you can try this - if it solves the problem - I didn't found an official link.

I am also having this problem, mostly while playing World of Tanks.  It seems to occur most often when running discord in the background.  It can trigger at any time.  Could be not at all some nights and the next happens a few times.  The only fix is to restart your computer.

Running on WIndows 10 MSI desktop PC.

Really need a fix as this is getting aggravating
