Any one seen anything like this before

In-game, uncheck the 'Enable Environment Shadows on Characters' in options. Also, if you have an ATI card, update (or roll back) drivers and/or enable Catalyst AI.

Already unchecked 'Enable Environment Shadows on Characters' and i am using a Nvidia card

Do you have any modules or haks installed?

no i do not and the only thing i can think of is that i switched my gpu to a 1080

In that case it may be a driver issue. Try switching drivers, ie. update if you haven't, or roll back to older drivers if you have. Sometimes drivers behave in odd ways between versions, and often people find one driver gives them grief where another does not.

Rolled back the driver for the only other available driver and its still appearing.

368.39 and 368.25 are the only drivers for the 1080 and since one has to be installed and other is the only option

I see. Maybe it is as you said, and the 1080 (and the drivers) don't get along with NWN's non-standard OpenGL. Old games often don't get along with new hardware.

installed NWN on my laptop and its working fine, except for some reson my keyboard does not work while in game.

Not even to input text?

reinstalled to C instead of E Drive and keyboard is working again, Debugmode worked
