There's a FPS diplay in the top right corner, left of the party area.
(1s) (6s) (12s) (48s) (lim)

Idk if it's from this game, it's only in this game, or if it's from something else...

How do I turn it off?

I don't know about what game this post is, but try to turn off a FPS counter in the game settings. It may also be a Galaxy FPS counter, so make sure to check the client settings as well.

Also some monitors may have the in-built FPS counter. Check if yours have any of such settings in its menu.

Those are four counters in seconds and some unknown abbreviation (limited?). What does that have to do with FPS? It's not. GOG Galaxy has a simple FPS counter with no additional information, and it only shows up if you press Ctrl+Shift+Tab.

I haven't use the GOG client in many years now, so I might forget about how some of its features work. Thanks for the correction.

Uhm... I thought this was the NWN1:EE forum. At least when I clicked on it, this forum appeared. Weird.

I meant NWN1:EE.

You can repost in the Neverwinter Nights series forum if you like.

OMG thank you so much.
I went and searched everything multiple times.
And used text search too.
Frame, FPS, Counter, but to think of the word "stats"...
