Actually tweaking ONE setting in 'UserSettings.xml' made a massive difference in KR.
Personally I prefer the KR client, however, I do think most of the art looks melted and/or out of focus. Male paperdolls are HIDEOUS...
The KR client is also unfinished... House gump doesn't have all the features (plus houses have a myriad of graphical glitches and annoyances), can't change reward titles, don't bother even attempting to change hues on a dye tub, mining is neigh impossible, and trading or dropping things is a hassle.
Other than that, the rest of the client (sans art) is superior to 2D. Macros are easier to make once you get used to the menu, and they can do far more. Crafting gump is superior, with only one flaw in the make # or make maximum part (failing to craft kills the repeats). And for me at least, it is much faster as of a few months ago – I consistently outrun people using 2D.
Saying that, SA is a “new client”. Give it a chance! Sign up for the beta to help make it better. 2D is holding UO back, it’s a 12+ year old client now and its age is showing. I would like to be able to play at a modern resolution in windowed mode and still be able to see things. 800x600 is so last millennium!
KR isn't perfect, nor is 2D (it needs UOA and UOAM to even pretend to be modern). But let’s cease the whining about a new client before you've even tried it.
