Default quake 2 screen effect - 27-07-2010

Hello, I want to know something.. if you ever played quake 1 or 2, you can remember some functions that resize the screen. I think you had to press + or - to size up or down the screen. well in CS 1.6 I cannot do that at the moment, I did a search in google and found that some commands are disabled for the game now. I tried the commands sizeup and sizedown but they have no effect. anybody knows a way to get this functionality, programatically or by a working cvar or command? thank you

I remember Doom I and II had that effect.
But I think counter-strike disabled that so you would have to choose which resolution to pick rather than using sizeup or sizedown.

I did a quick search and found that the screen resizement is handled by some internal variables (cvars) ... I was looking into the quake2 source code since it is the basesrc for hl1 src code. I am 100% sure that this can be done in CS1.6 apart of those disabled commands (sizeup and down). so I still ask if anyone knows how this can be done.

Code:
vid_dll.c
// Global variables used internally by this module
viddef_t viddef;    // global video state; used by other modules

/*
** VID_NewWindow
*/
void VID_NewWindow ( int width, int height)
{
 viddef.width  = width;
 viddef.height = height;
 cl.force_refdef = true;  // can't use a paused refdef
}
/*
============
VID_Init
============
*/
void VID_Init (void)
{
 /* Create the video variables so we know how to start the graphics drivers */
 vid_ref = Cvar_Get ("vid_ref", "soft", CVAR_ARCHIVE);
 vid_xpos = Cvar_Get ("vid_xpos", "3", CVAR_ARCHIVE);
 vid_ypos = Cvar_Get ("vid_ypos", "22", CVAR_ARCHIVE);
 vid_fullscreen = Cvar_Get ("vid_fullscreen", "0", CVAR_ARCHIVE);
 vid_gamma = Cvar_Get( "vid_gamma", "1", CVAR_ARCHIVE );
 win_noalttab = Cvar_Get( "win_noalttab", "0", CVAR_ARCHIVE );
 /* Add some console commands that we want to handle */
 Cmd_AddCommand ("vid_restart", VID_Restart_f);
 Cmd_AddCommand ("vid_front", VID_Front_f);
 /*
 ** this is a gross hack but necessary to clamp the mode for 3Dfx
 */
#if 0
 {
  cvar_t *gl_driver = Cvar_Get( "gl_driver", "opengl32", 0 );
  cvar_t *gl_mode = Cvar_Get( "gl_mode", "3", 0 );
  if ( stricmp( gl_driver->string, "3dfxgl" ) == 0 )
  {
   Cvar_SetValue( "gl_mode", 3 );
   viddef.width  = 640;
   viddef.height = 480;
  }
 }
#endif
 /* Disable the 3Dfx splash screen */
 putenv("FX_GLIDE_NO_SPLASH=0");
  
 /* Start the graphics mode and load refresh DLL */
 VID_CheckChanges();
}
