Yes what I did.
My save #1... Loaded up GE and deleted loads of American Elm stage 01 trees, replace with bushes to fill.
My save #2... Loaded up GE and deleted ALL trees. Created my own tracks of forests at much thinner levels.
But, I love working in Giants Editor and understand most probably can't be bothered.
I have a 4070ti/1-7 12700k holding 141fps@60c on high settings. The map runs very well.
