ZellSF: I really disagree that Neverwinter Nights 2 supports high resolution. Unless we're in 2000 and high resolution means 1024x768.
It needs a mod to make the game properly scale some UI elements at 1080p...
Not had any problems running NWN2 at 2560x1600 myself. It doesn't make full
use of the screen but the relevant files are in XML and easily editable. Change partybar.xml so the line starting
<UIScene name="... has a
height= value of 1200, say (to allow more party members to be listed down the right hand side of the screen) and edit the quickspell.xml and increase the height there similarly (say to 626) to accommodate high-level multiclass spellcasters (apologies for not including the files in my post, but GOG's forum won't allow any attachments other than images).
MysterD: Better UI, better graphics/texture-work, improving performance with a new x64 bit EXE, and/or any other graphics bells & whistles they want to add (SSAO, DLSS, DLDSR, RT, etc) would be why to do a Enhanced Edition.
NWN2's UI is highly customisable (unlike the original NWN) and there are mods aplenty for those who want to change it. Performance should really be a non-issue (yes, NWN2 was a beast when it was released in 2006 but now even the humblest laptop should be able to handle it at maximum prettiness) and even if it was, since when have Beamdog ever improved performance? NWN itself had a minimum specification of 450MHz Pentium II and 128MB RAM plus a 16MB OpenGL 1.2 compliant video card. NWN:EE? 1GHz + processor, 1GB RAM and a 1GB OpenGL 3.0 video card. Quite a step up for what have been reported as
small differences. Oh, it's 64-bit only too.
As for graphics, NWN 2 would benefit most from more detailed textures - of which a good list can be found
here.
However a more recent entry is at Neverwinter Vault - the
2022 HD Texture Pack. No EE needed.
Transparency anti-aliasing is a big plus also (removing jaggies from tree leaves and character hairlines) but that's a graphics driver option.
As for the other graphics options, DLSS is irrelevant for a game that can be run at maximum resolution, DLDSR is only appropriate for games limited to lower resolutions (not really an issue with NWN2), SSAO (in my experience) is limited to indoor settings and has a marginal effect while Ray Tracing would involve a major engine rewrite and performance hit for less-than impressive gains (every object and location would have to be redone with higher quality models for full effect, and that ain't gonna happen with Beamdog's budget).
