Fps drop when moving mouse in-game

Hello warmane! I’ve recently just come back to warmane to play with some mates after a long break. But as i just downloaded the game, logged into the world i immediatly started getting insane fps drops as i moved my mouse around. I tried everything of the basically regarding vsync on/off in both the nvidia control panel, as well as in game. I tried windowed and borderless. To No luck.
I turned off ”raw mouse input”, as it generellt fixed my issue of the fps drop. However, the mouse feels…slow and sluggish now.

The hardware is not an issue as far as i know,
I’m running:
Intel i9
ASUS RTX3080 STRIX
32GB ram
Game located on a SSD drive.

Is there a way to run raw mouse input with this client? Or could it be that the client Itself is to old? I’ve got No issues what so ever in blizzards TBC-Classic version of the game.

in-game: Menu -> Video -> disable "hardware cursor"

This should solve the issue. Btw it is caused by a recent nvdia driver so you can downgrade to a previous version as solution if you want.
