I have checked not to use the nova effect. but how in the game can still see the nova. I don't want to see that effect, because of the old laptop problem. any solution?

first of all you should set visibility range to max
and all gfx settings to max
even the old gfx cards can handle Knight Online easy

have you tried to check the box than save!
load game
than close and open options
uncheck box and save again

I have no problems with those settings.
Its working fine for me and for other people it seems.
