I don't know exactly why but suddenly as of a few days ago NWN is not getting any frames when I connect to the server. If I load a single player campaign the game runs without a flaw or fault.
Does anyone have any possible ideas or fixes? I did find setting compatability mode to Windows 95 would cause it to run somewhat better. But only enough to sit in the square and 'talk'.
Did your computer install system updates in that time period? It might have included a network adapter driver that's causing packet losses. If you do other network-intensive gameplay, do you see frame rate issues with them?
Check your in-game graphical settings as well. Turn off grass and shiny water, etc.
Fixed via reformat. Latest windows update destroyed ze game.
