How do I force a video mode?

Follow these instructions to configure your video mode and resolution before launching a game:

Note: If you are forcing a refresh rate on your system (this is not recommended), you will need to ensure that you specify the forced refresh rate in the launch options.

1. Open Steam
2. Go to the "My Games" tab
3. Right-click the game which needs to be reconfigured
4. Select "Properties" from the menu
5. Click the "Set launch options..." button
6. Add -gl at the end of the line, be sure to include a space before the "-" and anything before it.
7. Specify the appropriate Video Mode and Video Option switches from the lists below

Video Mode Launch Options

Use the -w # switch (where "#" is a number from the list below) to specify the display resolution:

• 640 (640x480) - GoldSource
• 720 (720x576)
• 800 (800x600)
• 1024 (1024x768) - This mode offers the best performance for most cards
• 1152 (1152x864)
• 1280 (1280x1024) - This mode is optimal for high-end cards
• 1600 (1600x1200) - This mode requires a high-end monitor and a high-performance card

Notes on Display Resolution Settings

Higher resolutions will affect the Frames Per Second which your machine can display (800x600 & up)

640x480 resolution may run slower than 800x600 resolution on newer video cards.

• -gl use the OpenGL engine - GoldSource
• -soft use the Software engine
• -width # (where "#" is the width in pixels of desired video mode) sets the video mode width
• -w # (see the Supported Video Modes list above)
• -fullscreen or -full use Full Screen mode (default)
• -startwindowed / -sw / -windowed / -window / -win use the Window display mode (game appears as a window on the desktop)
