I am unsure if its 8.1, there's nothing to suggest there is, but there is also nothing to suggest it isn't. I am thinking the dual core and the video card is the problem. I may take this machine back and get the smaller one, with an Intel card rather than AMD. Non of the fixes I've found in the NWN support channels seem to be helping.
-Shiny water is off (regardless, I don't even make it pas the loader screen where you select Play, DM, Toolset, Options, ect.)
-Skyboxes are off
-Afinity is set to -2, -1, 1, 0, so on. I've tried every setting.
-Compatibility is set to every possible variation available, and I cant even access config anymore.
-reinstalled several times
