Team Fortress 2 is an awesome game. If you are a gamer who loves sharp textures you might find the following console command for Team Fortress 2 useful. The command is mat_picmip -0.9 and has the effect that the textures in the game look much sharper than before.
The default value is 0 which seems to reduce the sharpness of the textures somehow. Changing that to the value -0.9 which is the lowest value that you can choose without being kicked from servers that are protected against cheating is effecting the graphic quality of the game tremendously.
If you have troubles opening the console try the following: Right-click on Team Fortress 2 in Steam and select properties. Add -console to the launch options. This opens the console by default and will bring it back whenever you hit escape in the game to see the menu.
Take a look at some of the before after screenshots to see what I mean:
