Since update to 1.22
there is an input lag on the mouse

No lag on keyboard nor gamepad ( a PS4 controler in bluetooth via DS4 )

I'm on windows 10 x64
fresh complete reset ( had to in order to fix windows apps issues )
The mouse is a Roccat Tyon
Tyon's drivers 1.16
firmware 1.31

The lag is so strong it create a strong framerate issue

So far I've unistalled The witcher 3 completely and redownload base games files.

I keep you guys posted.

Edit :
Confirmed, the input lag seems to not appear in 1.21

Edit 2 :
Done some testing
In 1.22 uninstalling Game Overlay in GoG Galaxy had solved the issue.
Need more test to confirm it is not linked to another DLC

Edit 3 :
Confirmed that the overlay is the only one cause of this severe imput lag
This is a trouble that can only appear when using an assemble of GOG Galaxy Beta and Witcherr 3 WH 1.22


Solution :

Unchecking " Game Overlay " box
You can find it under "parameter" inside Gog Galaxy client
over all DLC installed.

Please admin close the subject.

I'm getting it too

Not entirely the same, however, as my controls partially or even completely locked up a couple of times so far, I'll assume it is a similar problem.

What I can clearly recall are two instances:

1. Right after Cerys' solution to "Possesed" controls locked up entirely. Reloaded the game, couldn't reproduce the error.

2. Ciri sequence in Hindarsfjall got a keyboard lockup out of the blue, mouse still responsive. Couldn't reproduce the hangup here either.
