I was flying in the swiss alps in FS, and I thought, "Hey, I'm getting 19+/- FPS with medium settings....I wonder how it will run with higher settings....."
So, in small increments, I started adding complexity too the mesh, water, etc.
I eventually ended with everything maxed out except the autogen, which I lest at normal, and the filtering which I left at bi.
It is amazing.
I'm still getting 7+/- FPS, giving me a semi-smooth flight.
I love my new computer ;D
