Higher definition models
The High Definition Pack[6] was created by Gearbox and first released alongside with Blue Shift on June 12, 2001. It was released for free on Steam on August 30, 2005, with a fixed version released a year later. This pack replaces most weapon and player/enemy models with higher polygon versions, substantially altering the style of some of them in the process. The option to enable the pack in-game is in the options menu, and the game must be restarted for it to take effect.
For the retail version of Half-Life and its expansions, the Official HD Pack can be found on PcGamingWiki.
For other options follow this guide.
Opposing Force's main menu, among other parts, was heavily changed with the game's transition from the WON (World Opponent Network) system to Steam. A mod was released by Reddit user HowardHeyman. It restores the look of the original Opposing Force menus, but without text subtitles, animated backgrounds, nor various options windows to keep within the Source Engine's assumed limits. The mod also adds main menu music from Opposing Force's own soundtrack. An alternate download link can be found here, on GameBanana.
The menu also adds the "Custom Game" feature that was present in the WON version, where the player could select from an in-game menu to switch mods in-game. This feature is disabled by default in the Steam release, as Half-Life doesn't have true native support to allow run time switching, and, according to Alfred, the engineering effort to fix the function is better spent elsewhere.[7]
- Menus are 4:3 by default and cannot be stretched to fullscreen. In-game is untouched.
Enabling developer mode
- Enabling developer mode will allow use of in-game cheats and various console commands.
|
Turn on developer mode[citation needed]
|
|
Use the developer 1 in console.
Notes
- The developer console can be opened by pressing ~ (Note you may have to turn it on in the in-game settings). You can use the console command
sv_cheats 1 to allow the usage of console commands such as god and noclip. Note that you might have to reload a save-game or do it at the main menu after enabling cheat-mode for certain commands to work.

Video
- Assets are designed for 640x480, and UI may be too small at higher resolutions.
|
Increase font sizes[8][9]
|
- Open
<path-to-game>\platform\resource\TrackerScheme.res in a text editor.
- Under
"Legacy_CreditsFont", change "tall" as desired to change the size of the in-game credits font, used for the opening credits, level titles, and tutorial prompts.
Recommended settings for a similar font size to that used in 640x480 are:
"30" for 720p or 768p
"40" for 960p, 1024p, or 1080p
"50" for 1200p
"60" for 1440p
"70" for 1600p
"80" for 2160p ("4K")
"120" for 2880p ("5K")
"135" for 3240p ("6K")
"180" for 4320p ("8K")
|
- When running at widescreen-resolutions adjusting the FOV is probably necessary.
|
Field of view[citation needed]
|
- While in game, open the console (~).
- Type
default_fov 106.270273206 and press ↵ Enter.
|
|
-window -noborder[citation needed]
|
- Find Half-Life: Opposing Force in your Steam Library
- Right-click the game name
- Select
Properties
- Select
Set Launch Options...
- Input
-window -noborder
- Press
OK
- Launch the game
|
- Game is capped at 72 FPS (without Vsync) by default.
|
Set FPS limit[citation needed]
|
- Go to the configuration file(s) location.
- Create a new file called
userconfig.cfg
- Add in the following lines:
fps_max "<desired FPS value>"
fps_override 1
- The
fps_override 1 command disables GoldSrc's arbitrary 100 FPS limit.
4. Save the file and launch the game.
5. Disable Vsync in-game.
Notes
- Doing this will break rope physics in the game, allowing you to climb them but not swing. Swinging is sometimes necessary to progress and the fps cap will have to be turned back on.
|
OpenGL overbright lighting
- Overbright lighting increases the rendering dynamic range, resulting brighter and more colorful visuals.
- Overbright lighting normally only works on the Direct3D and software renderers.[10][11]
|
Nvidia cards: Enable the GL extension limiter[12]
|
- Download and run Nvidia Profile Inspector.
- On the Half Life profile, set
Extension limit to On. Apply changes.
- Go to
<path-to-game>.
- Create a file called
autoexec.cfg.
- Add new line
gl_overbright "1".
- Save the file.
Notes
- Doing this will disable multi-texturing, which has the side-effect of disabling detail textures, which may effect the appearance of other games and mods that share
hl1.exe, including Counter-Strike: Condition Zero and Day of Defeat.
- Doing this disables the Steam version's built-in MSAA. On the Half Life profile, change
Antialiasing - Mode to Override any application setting and Antialiasing - Setting to the desired level of antialiasing (such as 4x [4x Multisampling] for a vanilla look, or 32xS [Combined: 2x2 SS + 8x MS] for maximum antialiasing).
