- For scrlines: threshold for lines to be scrolled.
- 0 - Always use scrolling. (default)
- 1 - Use full page redrawing.
- > 1 - If the lines to be scrolled is grater or equal to the
- specified value, use redrawing. Otherwise use
- scrolling.
-
- If you feel scrolling a page (CTRL-F) is too slow with DirectX
- renderer, try this "scrlines" option.
- When set it "1", Vim uses full page redrawing instead of
- scrolling. Redrawing a page is faster than scrolling a
- page in some environments.
- After that, when you feel scrolling lines (CTRL-Y) becomes
- slow, please try "2" or greater value for this option.
- It works threshold line number to switch scrolling to
- redrawing. Scrolling a few lines might be faster than
- redrawing a page in some environments.
+ For scrlines:
+ This was used for optimizing scrolling behavior, however this
+ is now deprecated. If specified, it is simply ignored.
