If it matters to anybody, I'm getting much better performance with the newest nvidia graphics driver on my laptop. I can even get 4k60 with few drops or slowdown. Before from the driver from earlier this month I was getting some slowdown at1080p.
As an aside, what's up with all the banding in this version of the game? In DSfix you could fix this by overriding the texture filtering. Is there no way fix this in the remastered version? Look at the sky and notice all the lines in the sky in the upper left corner.
New Londo Ruins has major banding as well. Too bad they didn't fix that, seems like it would have been an easy change to make.
