Issues fixed

Run the game at screen refresh rate (Retail version)

The retail version of the game defaults to 60 Hz when running with Direct3D renderer in full-screen mode.
Use the -freq <rate> command line argument[2]
Example: -freq 120 forces a 120 Hz refresh rate.

Input Lag in Direct3D (Retail version)

On certain graphics cards, using the D3D renderer can result in severe input lag, even with disabled VSync.
Set gl_d3dflip 1 in the console[3]

Main menu issues (Retail Version)

In modern versions of windows the menu is usually not seen in full screen in addition to crashing when loading the game
Run the game in compatibility mode for Windows XP (Service Pack 2)

Fatal Error - Available memory less than 15MB (Retail version)

Run the game in compatibility mode for Windows XP[citation needed]

Black screen on startup (Steam version)

Disable FBO rendering[4]
  1. Add -nofbo in the game's launch options.

Windows 7/Vista Performance Fix

In Windows 7 or Vista with modern hardware, some users may experience extremely low frame rates during gameplay.
Set HL.exe to high priority[citation needed]
  1. Open Half-Life.
  2. Press Ctrl+ Shift+Esc in order to open the Task Manager.
  3. Under the Processes tab, find HL.exe and right click it.
  4. Set its priority to high.

Performance issues with dynamic lights on Intel graphics (OpenGL)

Dynamic light sources being present, such as the flashlight or flickering lights, causes significant frame rate drops and lag spikes on Intel graphics.
Use this GLIntercept config[5]


As this method uses a custom OpenGL32.dll, it should not be used in VAC-protected servers.
Doing this also fixes overbright lighting.

Glitchy mouse movement in-game

Enable raw mouse input in the game's mouse settings[6]

Day of Defeat Classic v3.1

DoD 3.1 Steam Installer
Server List
DoD 3.1 Steam Community Group
Day of Defeat became an official Valve mod and was released as version 1.0. Prior to this Day of Defeat saw a number of revisions ultimately leading up to the final pre-official version of 3.1. With the release of 1.0 many of the gameplay elements changed and previously popular maps were removed from the game.
Because of the niche nature of playing this version most game sessions are organized through the DoD 3.1 Steam Community Group.
