Do you happen to have a screenshot comparison? The SRO clutter textures (urns, pots, etc) looked extremely low res to me, unless those are not the textures that you overwrote from SRO.
... in your opinion. :)
I would also not say a lot... just some. I use the vast majority of RCI.
Perhaps I did something wrong with my installation. I trust your judgement. It would be cool if you had a screenshot so I could make sure I'm not mistaken.
