Saints Row :Gat Out Of Hell almost completely max out at 1920x1080p on single Ge Force GTS 450 card.
As you can see i had only reduced Lightning Detail to Low..because its very taxing on High it make a big fps drop.And there is almost no visual difference.
GTS 450 is still very good GPU..everything depends from sofware optimization people.
