Blungo"If you have a newer video card, lower dxlevels, will actually slow down your video rendering resulting in lower frames per second"
does this still apply?
also got some questions about if the -high launch command still increases input lag and what -nod3d9ex does which i found in your original fps cfg post
about -high, yes, it does.
-nod3d9ex disables steam in-game overlay
