it works! after a little experimenting i've settled on speed 255 and sensitivity 150.
an acceleration might be good. even at speed 255 (the max) the pointer doesn't cross the screen super-fast. but at 255 it's starting to be tricky to be precise over very short distances.
there's maybe a similar issue with sensitivity. at 150, still having to push a bit to get to the other side of the screen quickly. but don't want to set any higher otherwise precision becomes tricky.
still, this is a great improvement. thanks lembas!
