Configs (CFG)
Configs refer to the configuration files which are used by the game to quickly change game parameters, such as graphics options. Many configs are designed to improve game performance through lowering graphics settings, as well as providing extra functionality through use of client commands, such as viewmodel_fov and interp settings.
FPS Configs
FPS configs strive to lower game graphics as much as possible in order to increase the framerate (FPS) of the game. Popular graphics configs include Chris's Highframes, Maxframes, and Dx9frames, while configs such as m0reframes have been used in the past.
Comanglia's FPS Config - The go to config for most competitive tf2 players who need more frames. It's considered by many to be one of the most effective configs current available.

TF2Mate - TF2Mate is the most popular config generator amongst the TF2 community. It allows players to configure their graphics settings, binds, and also comes with a crosshair switcher that allows the user to pick their own crosshair for each weapon slot on each class.
Chris' Configurations - Chris' Configurations, or, simply "Chris' Configs," are FPS configurations of which, up until recently, was maintained by Chris. This config is highly popular and is used most of the time by TF2 competitive players. Chris' Configs come in several different versions, the most popular of which is the "maxframes config", which gives the maximum framerate possible while at the same time reducing the quality of the textures and the overall look of TF2. Alternatively, players can go for the "Highframes config", which makes TF2 look a little better compared to "Maxframes" but at the expense of not getting the maximum possible framerate.
m0re FPS Configurations - m0re FPS Configurations is the FPS config which pales in comparison to Chris' Configs due to performance but is a healthy alternative to Chris' Configs.
