How to uncap or limit FPS in TF2
Type fps_max 0 in your game console from the main menu to remove the frame cap, or set a limit like fps_max 240. The default is 400.
fps_max
Caps your frame rate. 0 removes the cap.
fps_max <fps> Examples
fps_max 240 Cap at 240 fps.
fps_max 0 No cap.
Arguments
fpsRequired- Frame rate cap. 0 is unlimited.
What it does
Many players set a cap a bit above their monitor refresh rate for steadier frame times. Set it in the main menu or autoexec.cfg because it cannot change while connected.
The game's own description: Frame rate limiter, cannot be set while connected to a server.
Run it on your server
On a SLASHPLAY server, type it in the Console tab of the server page; the reply shows right under it. A value set there lasts until the server restarts. To keep it, add the line to tf/cfg/server.cfg. New to this? Start a TF2 server first.
