According to Pete's readme file:
- All plugins: _Demo_ suggested to use a 59.94 fps
NTSC timing (instead of the old 60 fps one), if auto-
detected fps limitation is enabled. Well, done... (don't
ask me if that will improve anything... most of my
games are PAL ones anyway
I don't know why either, but the framerate limit is set to 59.94(the on-screen display shows only 59) instead of 60.
