Name

Description

›-allowmultiple

On Windows, launch multiple copies of ezQuake rather than re-using the existing instance

›-basedir

The "base" directory is the path to the directory holding the quake.exe and all game directories.

›-bpp

Allows setting of 'r_colorbits' cvar during start-up

›-cdaudio

Enables CD audio playback in builds compiled against `cd_linux.c` or `cd_win.c`; the default build links `cd_null.c` which is a no-op.

›-cddev

On Linux, specifies the cd device to use.

›-cheats

enable cheats on local server (/noclip etc)

›-clientport

Sets the local UDP port the client socket binds to on startup (`-clientport <number>`), overriding the `cl_net_clientport` cvar default (27001).

›-conbufsize

set size of console buffer

›-condebug

log all console output to qw/qconsole.log

›-conheight

set vid_conheight during startup

›-conwidth

set vid_conwidth during startup

›-d

›-data

Adds `<datadir>` as an additional game data directory on top of the standard search path (`-data <path>`); may be specified multiple times.

›-democache

create memory buffer during startup, used instead of writing directly to disk when recording demos

›-detailtrails

sets /gl_particle_fulldetail 1 during startup

›-dev

Enables developer mode, which unlocks development-only commands (`devmap` plus the `dev_*` family including `dev_physicsnormalset`, `dev_help_issues`, `dev_help_verify_config`, `dev_dump_defaults`) and extra cvars (`r_speeds`), and activates Vulkan validation layers when using the Vulkan renderer.

›-display

Selects the monitor index (0-based) for rendering (`-display <index>`).

›-enablelocalcommand

Enables the server-side `localcommand` console command, which executes an arbitrary OS shell command on the server host.

›-forcetexturereload

Forces textures to reload from disk on every load call, bypassing the in-memory cache check that normally skips re-uploading a texture whose path and dimensions already match.

›-freq

Sets the fullscreen display refresh rate in Hz at startup (`-freq <hz>`), overriding `vid_displayfrequency`.

›-game

Sets the active game directory to `<modname>` (`-game <modname>`), overriding the default mod search path; affects which directory generated files are read from and written to (subject to `-nohome` / `+gamedir` interaction).

›-gamma

Sets the initial gamma value at startup (`-gamma <float>`, range 0.3-3.0), overriding the `gl_gamma` cvar default before the first frame.

›-gl_ext

Prints the GL_EXTENSIONS string to the console at startup.

›-gl-forward-only-profile

Requests an OpenGL forward-compatibility context flag (`SDL_GL_CONTEXT_FORWARD_COMPATIBLE_FLAG`) when creating a core-profile GL context on non-Apple platforms.

›-glsl-renderer

Forces the GLSL (modern OpenGL) renderer by setting `vid_renderer` to 1 at startup.

›-heapsize

Sets the hunk memory allocation to `<kilobytes>` (`-heapsize <kb>`, e.g.

›-height

Sets the vertical resolution in pixels (`-height <pixels>`).

›-ip

Binds all network sockets to the specified local IP address rather than all interfaces (`-ip <address>`).

›-maxtmu2

Caps the number of active texture units to 2 even if the hardware reports more.

›-mem

Sets the hunk memory allocation to `<megabytes>` (`-mem <mb>`, e.g.

›-minmemory

Sets the hunk allocation to the engine minimum (~5.3 MB); takes no argument.

›-no24bit

Disables loading of 24-bit (high-resolution) replacement textures (PNG/TGA external files), forcing the engine to use original 8-bit palette textures only.

›-no-accel-visuals

Requests un-accelerated graphics (used in debugging to create OpenGL 1.1 context)

›-noatlas

Disables texture-atlas batching of HUD/UI graphics; each draw call binds its own texture instead of sampling from a packed atlas.

›-noconinput

Disables reading console commands from stdin.

›-nodesktopres

Disables use of the desktop resolution for fullscreen mode, forcing the engine to apply an explicit resolution instead of matching the current desktop size.

›-noerrormsgbox

›-nohome

Disables the per-user home directory (`Documents\ezQuake` on Windows, `~/.ezquake` on Linux/macOS), forcing all file I/O to use the base game directory only.

›-nohwgamma

Disables hardware gamma ramp support.

›-nohwtimer

Disables the Windows high-resolution hardware timer (`QueryPerformanceCounter`) and falls back to the multimedia timer at 1 ms resolution.

›-noindphys

Disables independent physics tick rate by setting `cl_independentPhysics` to 0 and `cl_nolerp` to 1, restoring the classic coupled rendering-and-physics frame timing.

›-nomtex

Disables OpenGL multitexturing in the Classic renderer (prevents loading of `glMultiTexCoord2f`, `glActiveTexture`, and `glClientActiveTexture`), and additionally disables fog rendering engine-wide.

›-nonpot

Disables NPOT (non-power-of-two) texture support, forcing the renderer to treat `GL_ARB_texture_non_power_of_two` as unavailable regardless of hardware capability.

›-norjscripts

Disables movement scripting at startup; alias for `-noscripts` with identical runtime effect.

›-noscripts

Disables movement scripting at startup by setting `allow_scripts` to 0, preventing use of advanced movement scripts such as rocket-jump or bunny-hop automation.

›-nosound

Skips SDL audio initialization entirely, leaving all sound subsystems inactive for the session.

›-nostdout

Suppresses stdout output on POSIX by setting `sys_nostdout=1` before `Host_Init`.

›-no-triple-gl-buffer

Disables persistent-mapped triple-buffering of GPU streaming buffers (VBOs used for once-per-frame uploads).

›-oldgamma

Switches gamma correction to the legacy palette-baking method, applying `vid_gamma_table` to texture data at load time instead of using the hardware gamma ramp.

›-particles

Sets the maximum number of simultaneously active particles to `<count>` (`-particles <count>`), overriding the `r_particles_count` cvar at startup.

›-port

Sets the UDP port the internal server listens on (`-port <number>`), overriding the default of 27500.

›-progtype

Sets the QuakeC VM interpreter type used by the server (`-progtype <int>`), overriding `sv_progtype`.

›-r-debug

enables OpenGL debug output.

›-r-dump-shaders

Write expanded shader source to qw/shaders/<name>.<type>

›-r-no-amd-fix

Disables the ATI/AMD driver workaround that avoids `glBindTextures` and forces `glMultiDrawArrays` in place of `glDrawArrays` on driver version strings containing `.13399` (github bug #416).

›-r-nocallback

Disables `glDebugMessageCallback` and `glDebugMessageControl` setup when the GL debug context is active (i.e.

›-r-nomultibind

Disables use of `glBindTextures` (GL 4.4 / `GL_ARB_multi_bind`) for batched texture-unit binding.

›-r-novao

Disables Vertex Array Object support in the Classic renderer; falls back to manual vertex-attribute setup per draw call.

›-r-trace

Enables full per-call GL API tracing to timestamped text files.

›-ruleset

Sets the active ruleset at startup by name (`-ruleset <name>`), applied before any config loads.

›-r-verify

Enables per-frame GL state verification: calls `GL_VerifyState` each frame to download actual OpenGL state from the driver and diff it against ezQuake's internal state tracker, logging any mismatches.

›-startwindowed

Starts ezQuake in windowed (non-fullscreen) mode.

›-userdir

Sets a named user-data subdirectory and path layout (`-userdir <dirname> <type>`), where `<type>` is an integer 0-5 selecting the path-construction formula (case 0 = relative to game directory, cases 1-4 = base-directory variants, case 5 = relative to home directory).

›-width

Sets the horizontal resolution in pixels (`-width <pixels>`).

›-window

Starts ezQuake in windowed mode and routes `-width`, `-height`, and `-display` to the windowed resolution cvars (`vid_win_*`) instead of the fullscreen ones.
