People have been saying, for a long time now, that launching TF2 with -dxlevel 81 helps fps stability, and while this is true for a lot of old pc's, a lot of people still say the same for newer pc's - with newer graphic cards
Mastercomms suggests using -dxlevel 100, which is basically running TF2 with -dxlevel 95, but using hardware to determine graphics capabilities.
What are your arguments for and against both dxlevels?
