This page contains instuctions on setting up the original version of Quake to run in OpenGL. Your 3D card must have OpenGL support in order to run GLQuake. Here is a list of steps that will get you fraggin' in no time.

• The full version of Quake 1 is required for GLQuake.



• Download the OpenGL patch (393K) for Quake 1. After saving the file in a temporary directory, double-click on glq1114.exe to install.  Keep in mind that GLQuake is unsupported by id Software.
  
  Note: Be sure to leave the 3dfx GL miniport check box unchecked when installing GLQuake. Otherwise, you will get the message "A required .DLL file, GLIDE2X.DLL, was not found." when starting GLQuake.
  
  If you end up getting this message, all you need to do is delete the opengl32.dll file that is installed in your Quake directory.



• Download the following two files which are from Microsoft's OpenGL Release for Windows 95: Opengl32.dll (722K) and Glu32.dll (137K).  Move these files to the \Windows\System directory.
  
  Note: This step is not necessary for users with service release 2 (SR-2) of Windows 95 or Windows 98/NT. OpenGL support is included in those versions of Windows.



• Create or update the Quake autoexec.cfg file. This file is located under the \Quake\ID1 directory and can be created or edited using Notepad.
  
  Add the following commands to the autoexec.cfg file to enhance the GLQuake graphics and improve performance:




r_mirroralpha "1"




r_shadows "0"




gl_flashblend "0"




r_wateralpha "1"




gl_polyblend "0"




m_filter "1"




gl_playermip "2"




_snd_mixahead ".14"

Note: Adding the characters "//" before a command will comment the line out. Click here to view a sample autoexec.cfg.


• Before running GLQuake, make sure your Windows desktop color palette is set to high-color, or 16-bit.



• Create a batch file to run GLQuake.  This allows you to change screen resolutions and to run in full screen or windowed mode.  Note that the command line in the batch file must be on one contiguous line.
  
  Open Notepad and copy either of the lines that appear in this pop-up window. Save the file in the same directory as glquake.exe is and name it something like glquake1.bat.



• Read about the excellent utility called idGamma on this page and use it. It is not required, but without it, GLQuake will be extremely dark.



• Double-click on your batch file and frag away!
