Well, you can do
M-x customize-variable RET preview-gs-options RET

and remove the -dTextAlphaBits=4, or replace it with
-dTextAlphaBits=2.  Removing it will have a drastic effect, replacing
it by the lower value much less so.

I don't see any other possibility to control subsampling.

Another thing to note is that installing and using outline fonts tends
to get sharper bitmaps as a result.
