Put these commands in the console, the console as you should know
by now is accesible during game or before, bind it in the controls
to a key, or by default its mostly the ` key (top left key under
developers 1 - shows you all sorts of informations on screen,
such as r speeds.
r_speeds 1 - shows you the r_speeds on screen (r_speeds are w_polys,
e_polys will go up the more complex your shapes are in those areas.)
cl_showfps 1 - shows fps on screen
net_graph 1 - shows fps and choke etc.
sv_gravity 100 etc - jump to places you cant normally get to
single player only:
Handy multiplayer one
hud_saytext_time 0 - turns off chat when spammer / idiotic person
on server is annoying everyone.
There is also a gl_wireframe 2 but this only works in single player
to stop people using it to cheat in multiplayer.(this command
is good when your trying to figure out an r_speed issue,cause
you can see what the engine is drawing while looking in a direction)(it's
also good to see how your textures are being applied on a brush
and how the engine resizes the textures on a brush).
if you need to get into gl_wireframe 2 mode just open map thru
console with "deathmatch 0" or compile the map with
deathmatch left out of the command line.(Just make sure you add
it back in when you do a final compile)
