Thanks for the clarification. I take it you are referring to dalingrin. I think I recall the issue being addressed in a thread but I can't remember exactly what was said or where it was brought up. Do you have the threads post number by chance, since any observations on his part are worthy of serious consideration. Just hoping to learn something new here. Thanks in advance.
Web page refresh showed post by chisleu which quoted dalingrin on the io issue. If this was the post You were referring to then please ignore the above request.
I read a lot of threads on a lot of forums. Yes dalingrin was the person I was referring to, however senior madcat has put out a kernel with the offending code removed and performance is increased.
It's noticably increased if you enable animation on the app window, enable fade in on the labels, set alpha to ~50% (on the background of the app tray) and set the animation time to 1 second or so.
The old kernel just couldn't do it. It was always choppy. You could set it faster or slower and it was still choppy, even with performance on.
I installed matcat's kernel this morning and the very first thing I noticed was it was able to do it perfectly smoothly.
good times. I was wrong! I love being wrong, especially when it means my nook is now more awesome.
