I have a same problem, my monitor shows interlace modes horrible bad.

Maybe we could beg Gunnar to make "unflicking Interlace", ie just normal planar gfx modes 320x512 / 640x512 (without intrelace) and promote interlaced modeas to this. (if user wants... Vcontrol and f11 key could control it...)

  Could not dblPAL and similar tricks produce less flickering picture?
  (modes for EURO monitors and similar?)
  You can make the Amiga produce it's display output at ANY vertical
  blanking frequency between 50 and 60Hz and even out of this boundary.
  Ordinarily low Hz interlaced modes could somewhat be first promoted to this and then re scaled.

Since I have eyesight problems I would be most interested in 70-75Hz modes only. Its far superior for eyes, high res is not my thing.
