r_novis (0/1) default: 0
This variable toggles the use of VIS information from the map data. When this
variable is set to "1" the game will calculate it's own VIS information on the
fly instead of using the information stored in the map data, this will cause
a severe performance penalty in the game. When "r_novis" is set to "1", the
variable "r_wateralpha" has a value lower than "1" and the server allows the
client to display water transparently the player will be able to see through
liquids. This is a nice effect to see but it is not recommended to keep this
variable set to "1" because of the huge performance penalty.
It is possible to enable transparent water and still keep this variable set to
"0" (and thus not experience such a severe performance drop) by using maps that
are VISed accordingly. You can visit the official Water VIS site at
"http://www.sod.net/" and download the vispatch program along with the patch
data files which you would use to update the VIS data for all of your game maps.
There are also map packs available that contain VISed versions of the original
ID maps.
0 = Do not calculate VIS information for unVISed maps.
1 = Calculate VIS information for unVISed maps.
