Update: I'm no longer updating this and have no plans to continue doing so.
Please check the following if you want a FPS config
sageComangliacoms is updated - Download - Changelog
TLDR: comanglia's config with a few changes and fixed suggested by mastercoms to improve fps - for example disabling low violence mode since actually lowers the FPS
Removed download link so it no longer works 10/22/2018
After having 3 other people use "My FPS config" as thread names I figured I should make an actual official thread about my cfg.
original post is here http://teamfortress.tv/thread/20172/my-fps-config
Max FPS for High Quality PCs// The Original Config that I use/update MUST HAVE QUAD-CORE OR BETTER CPU
Launch options "-dxlevel 81 -full -w WIDTH -h HEIGHT -console -novid"
Max FPS for Mid Quality PCs // Also known as Max Stability
Launch options "-dxlevel 81 -full -w WIDTH -h HEIGHT -console -novid" (remove the -dxlevel 81 for better stability with ALT+Tabbing)
FPS config for New Players
Sometimes my FPS config goes to far, and disables a lot of useful information that helps players learn the game / new maps. Base of this CFG is most like Max Stability.
