From what I understand that mod contains a 15-km atmosphere, which would probably tax my graphics card considerably & getting a newer one really isn't an option as it would void my pc's warranty (plus there is the cash flow problem to consider, eg: I ain't made of money). I fell into the "get a better video card" trap with my old pc & it turned out to be a big waste of money.

The "better"

card that I bought was overpriced & didn't improve my gaming experience by very much.
I'm sure that it's a great mod but is there a way to fix the issue without it?
