You can use user customization files to override specific settings in mastercomfig.

These are autoexec.cfg, which runs at game launch, and the 9 class configs (scout.cfg, soldier.cfg, pyro.cfg, demoman.cfg, heavyweapons.cfg, engineer.cfg, medic.cfg, sniper.cfg, and spy.cfg) which run on switching to a new class. All of these files go into a folder called user you create in tf/cfg.

If you don’t have these files, you can download the mastercomfig template and move the user folder to your tf/cfg/ folder to customize the config.

If there’s something you’d like to run for all of your class configs, you can add it to tf/cfg/user/game_overrides.cfg.

Utility Commands

  • run_modules: Applies modules. Useful for changing module levels in-game, and then applying them all at once.
  • apply_user: Runs user modules, applies modules and then runs user autoexec. Useful for changing your user preferences in-game.
  • restore_preset: Restores modules back to preset defaults, without using user settings.
  • restore_config: Runs all of mastercomfig and user configs again, resetting changes made in-game.
  • version_comfig: Outputs the version of mastercomfig currently being used.
  • switchconsole: Command for toggling console and console output. This is able to reduce the performance impact of console logging when the console is not toggled on.

Game Overrides

Some modules set something called game overrides, which apply settings that override map or in-game only settings that can’t be applied at launch.

If you want to override this part of the module, you will have to use their game override alias in tf/cfg/user/autoexec.cfg. This is comprised of a override alias, which is run during game overrides, and an override option, which actually contains the settings which is run by the override alias.

  • lighting: Uses lightmaps_override to control if lighting is blocky or smoothed out

    • lightmaps_off: Makes lighting blocky
  • shadows: Uses shadowlod_override to control the model quality shadows render with

    • shadowlod_low: Uses the lowest model quality to render shadows
    • shadowlod_high: Uses the highest model quality (at root LOD) to render shadows
  • water: Uses cheap_water_override to control the low quality water fade distance

    • cheap_water_full: Always uses fully cheap water
    • cheap_water_partial: Always uses partially cheap water, uses fully cheap water at a short distance
    • cheap_water_minimal: Uses partially cheap water at a short distance, uses fully cheap water at a further distance
    • cheap_water_never: Never uses any kind of cheap water
  • props: Uses detail_props_override to control grass/detail prop rendering and its render distance

    • detail_props_none: Disables detail props
    • detail_props_medium: Enables detail props, at a far distance, with no fade in
    • detail_props_full: Enables detail props, at a far distance, with a gentle fade in

So, for example, if you are using a lower lighting module, and do not want blocky lighting, you can add alias lightmaps_override to your autoexec.cfg.

Or, if you are using a lower water module, but do not want to use cheap water, you can add alias cheap_water_override cheap_water_never.

Network Aliases

These aliases are used by mastercomfig to apply network settings per class (as listed below) when using the snapshot_buffer=auto module level.

You can run them manually in your class config if you play a subclass, like Demoknight or Huntsman.

You can also re-alias them to use your own network settings.

  • net_projectiles: Alias for network settings on projectile classes (Soldier, Pyro, Demoman, Medic) (snapshot_buffer_low).
  • net_hitscan: Alias for network settings on hitscan classes (Scout, Heavy, Engineer, Sniper) (snapshot_buffer_safe).
  • net_spy: Alias for network settings on Spy (snapshot_buffer_low).

Changing your preset

mastercomfig supports selecting a preset after download. Add a file to your user folder called pre_comfig.cfg. In this file, put your desired preset as preset=preset-name. Preset names are:

  • none
  • ultra
  • high
  • medium-high
  • medium
  • medium-low
  • low
  • very-low

You can check the current selected preset by entering preset_level into console.

Optional Aliases


These steps are entirely optional and are only for advanced customization.

You can change the name of your user/autoexec using the autoexec_c alias and the name of your user/modules.cfg using the modules_c alias. This means your user preferences can have multiple different options, sort of like presets, but for your own preferences! Change these aliases in-game and use the apply_user command to apply your new user selections. This can be used for having different quality choices or game configurations for different scenarios or mood.

You can change the name of your custom class configs using the class_config_classname alias. For example, you can put alias class_config_heavyweapons"exec user/myheavy.cfg" in tf/cfg/user/autoexec.cfg if you want to use the file tf/cfg/user/myheavy.cfg for Heavy.

You can change the name of your custom game overrides config using the game_overrides_c alias. For example, you can put alias game_overrides_c"exec user/mygameoverrides.cfg" in user/autoexec.cfg if you want to use the file tf/cfg/user/mygameoverrides.cfg.

You can also get creative and use the aforementioned aliases to change your class config on the fly using binds or the console. For example, you could have different class configs for Scout in competitive and casual and then change your class_config_scout alias to run your preferred class config when you want.

If you want to run something only the first time you spawn and never run again while you keep the game open use the game_overrides_once_c alias.

Optional User Config Template


These steps are entirely optional and are only for advanced customization.

To get an idea about what to put in your user/autoexec.cfg and select options, you can download the autoexec template from the latest release.

This config is only for advanced, fine-tuned customization and is completely optional. Modules are recommended to be used for granular customization.

Debug Commands

mastercomfig provides a set of handy debugging commands used during mastercomfig’s development to analyze several aspects of the game.


  • debug_output: Enable developer only output. Shows various warnings about potential issues, and outputs console to the corner of the screen.

Gameplay Testing

  • debug_instant_respawn: Turns on fully instant respawn.
  • debug_invulnerable: Toggles buddha mode (health cannot go below 1).
  • debug_bots: Fills the server with bots with AI.
  • debug_target: Adds a target bot, which can be damaged infinitely.


  • debug_occlusion: Turns on debugging of the occlusion system.
  • debug_pixelvis: Turns on debugging of the pixel visibility system.
  • debug_fillrate: Shows overdraw from repeated passes.
  • debug_matsys_reload: Reloads material system.


  • debug_sound_loads: Dumps the current state of the sound memory pool, and enables debug output for sound loads.
  • debug_sound_dsp: Enables debug output of DSP parameters of sounds, and enables visualization for automatic room DSP, if it is enabled.


  • debug_network_packets: Enables spew of each network packet sent and received, including compression information if relevant.
  • debug_network_drops: Enables debug output of outdated or duplicate packets.
  • debug_network_graph: Enables the full networking graph, which displays information about packet volume, interp timings, and packet rates.
  • debug_network_pred: Enables network prediction error logging.


  • debug_fps: Enables the basic networking graph, which is handy for seeing FPS. Note that the graph has a noticeable performance impact.
  • debug_fps_range: Enables full FPS counter, which shows absolute FPS mins and maxes. You can re-run this command to reset the mins and maxes.


  • debug_vprof_spikes: Logs spikes below 100FPS (can be adjusted with alias debug_vprof_spike"vprof_dump_spikes 100") to tf/vprof_spikes.log (can be adjusted with alias debug_vprof_log_spike"con_logfile vprof_spike.log").
  • debug_vprof_dump: Logs profiling data to tf/vprof.log (can be adjusted with alias debug_vprof_log"con_logfile vprof.log"). Can be re-run to reset timings data.
  • debug_vprof_report: Logs a longer set of inclusive profiling data to tf/vprof.log (can be adjusted with alias debug_vprof_log"con_logfile vprof.log"). Can be re-run to reset timings data.
  • debug_vprof_off: Turns off profiling.
