Graphics
Settings (Continued)
r_nocurves
"x". Set this to 1 to disable curves & vastly improve performance. You may
notice visual faults in maps though as a result. I’d
recommend setting it to 0.
r_norefresh
"x". Not a tweak as such although setting x
to 1 will freeze
the screen. Leave it set to 0
at all times. This is included here more as a warning than
anything else.
r_overBrightBits
"x". Default is 1. Increase this to make the game brighter. The brighter the visuals
the more washed out the textures will look. Adjust this to
suit your own needs. If you change this to 0, you
should also change r_mapoverbrightbits to 0 as
well.
r_picmip
"x". A setting of 0 gives best image quality. Setting it higher (up to 4) may improve
performance but reduce image quality. I’d recommend
leaving this at either 0 or 1.
r_smp
“x”. Use a value of 1
to enable support for multiple processors in
supported Operating Systems. In order to get the benefits
from SMP, you must be running a SMP capable OS e.g. Windows
2000 & have an SMP capable Graphics Card driver
combination. Leave this set to 0
unless you have such a system.
r_stencilbits
"x". If you enabled Volumetric shadows
previously, then you’ll want to set this to 8. NOTE – Your Graphics Card must feature a stencil buffer to do
this, e.g. Geforce.
r_subdivisions
"x". Use this to set how complex (rounded) the
curves will be in maps. A setting of 1 gives the most detailed (smooth) curves. A setting of 999
gives the least smooth curves but improved performance. You
should play around with this value for yourself until you
find a good balance between performance & detail.
r_swapInterval
"x". This is the Castle Wolfenstein equivalent
of vsync. Vsync
effectively limits the frame rate to your current refresh
rate at a given resolution. Performance can improve with
vsync disabled (Frames are rendered as fast as they
can be regardless of refresh rate), although you can
experience image tearing &/or controller lag as a
result. With vsync enabled you won’t experience
either image tearing nor controller lag, although frame rate
will be limited to your refresh rate. As such I’d
recommend enabling vsync for best image quality &
disabling it when you intend to benchmark system/game
performance. Set x to 1 to enable vsync,
while a setting of 0 will disable it.
r_textureMode
"x". x
controls the Texture filtering method to be used in Castle
Wolfenstein. Options available being (From worst to best);
GL_NEAREST_MIPMAP_NEAREST,
GL_LINEAR_MIPMAP_NEAREST (Bilinear),
GL_NEAREST_MIPMAP_LINEAR,
GL_LINEAR_MIPMAP_LINEAR
(Trilinear).
Setting
it to GL_LINEAR_MIPMAP_LINEAR
(Trilinear) will yield best image quality – improved
texture sharpness & reduced texture aliasing. Those with
3dfx Graphics Cards should set this to GL_LINEAR_MIPMAP_NEAREST
(Bilinear) as they do not simultaneously support Trilinear
Texture Filtering & Multi-texturing. Those with most
modern Graphics Cards should be able to use GL_LINEAR_MIPMAP_LINEAR
without much performance hit. Setting this to other
options can improve performance, but will give increasingly
worse image quality.
r_ignoreFastPath
"1".
When x is set to 1 Castle Wolfenstein will ignore
any optimized rendering paths available – which may be
useful for troubleshooting purposes. For optimal performance
set this to 0.
r_simpleMipMaps
“x”.
Leave this set to 1 to enable Mipmapping.
This will smooth
transitions between textures (more specifically, between Mip-map
levels). Setting it to 0
may improve performance, although will reduce visual
quality.
r_flares
“x”.
Set x to 1
to enable light flares in the Game, this allows
effects such as light flares to occur. Setting it to 0
will improve performance.
r_lodCurveError
"x".
x (Default of 250) determines how polygons are
culled from a scene when further away. When set to a low
number, polygons are culled off at shorter distances, while
when x is set to a higher number they are not culled
for a long distance. For optimal image quality increase
this value (Objects remain detailed for longer) & vice
versa.
r_intensity
“x”.
x defines the overall RGB intensity, higher values
will effectively increase brightness although textures will
lose some of their quality.
r_ext_texture_env_add
"x".
When x is set to 1 additive blending is
enabled in Multi-texturing. If not supported only
multiplicative blending is used. Set this to 0 to disable
this, you shouldn’t have to do this however.
r_ext_compiled_vertex_array
“x”.
Setting this to 0 may fix a problem with flickering
textures in the game. Ignore this setting if you
experience no such artefacts & leave it set to 1.
r_ext_gamma_control
"x".
Set this to 1 to enable the gamma to be set
via the graphics cards OpenGL driver rather than using the
games settings. Set this to 0 to disable this
feature. This is useful if you wish to set your gamma
settings via a utility in the Windows Display Options menu.
r_allowExtensions
“x”.
This is the same as the Allow GL Extensions setting
in the Graphics menu, leave it set to 1 (enabled).
r_inGameVideo
"x". Setting x to 1 will enable
in-game video’s to be displayed. This may reduce
performance in most machines, although if you have 128MB RAM
or more you should be able to leave these enabled.
Set x to 0 to disable in-game videos
being displayed for optimal performance.
Make
sure to take a look at the TNT/GeForce,
Voodoo3,
Voodoo4/5
or Kyro
1/2 Tweak guide for information on how to optimize the
performance/visual quality of those cards. These may help
you improve image quality/performance even further than
Config tweaks can.
