Hello, I have a problem that makes the game unplayble. I tried to read about it but their are not any solution that worked.
The game works perfectly fine even in heavy combat situation, but then if I decide to pause, their is a huge slowdown. Actually it is not even a slowdown, it is like the game freezes, and defreezes for 1 secondes every few seconds. It is the same problem on the level up screen, when I have to choose my skills.

While it is possible to play withouth pausing, this bug is gamebreaking and makes the game much less enjoyable ...

I use a laptop for playing, it runs Windows 10. Graphic card intel HD 4000. Processor intel i53317 CPU. 4 GB RAM.

Thanks you for you help.

Also, the same happens when i press escape for the menu. The menu is stuttering, and it takes forever to save. Then when I resume the game it runs smoothly. It is very strange, because it is related only to the moment in game when the time stops .... So I dont think it is releated with hardware and system requirements ....

Which game?

NeverWinter Nights 1 Diamond, version 1.69 did not work, then I tried the community patch and it is the same.

I've had it running flawlessly on an Intel 3000, you should be fine as far as hardware goes.

Be sure to have direct X 9.0c installed.
Turn off shiny water.
Try different rendering options.

Are you playing single player or multiplayer? If mp, this can happen when a lot of action is happening with a lot of players.
