Rendering – OpenGL support
If
you’ve selected OpenGL
then set it as follows. Although, you should try using the
Direct3d renderer before using OpenGL.
Coronas.
Set this to True.
This is the haze of light that appears around light sources
in the game, such as lamps in the game. Set it to False
if you need extra performance (very slight at that).
HighDetailActors. Set this to True for
better visuals. Setting it to False
will improve performance.
ShinySurfaces. Shiny surfaces are the reflective surfaces in the
game, e.g. on some floors you can see your (& others)
reflections. Setting it to False will improve your
frame rate in such areas. I’d recommend setting it to False.
VolumetricLighting.
Set
this to True for
better visuals (effects like fog), although with lower
performance. Setting this to False
will result in a big frame rate increase. On most
graphics cards that have trouble running Unreal setting this
to False may mean the difference between a playable
& an unplayable game.
You'll
want to do some more advanced editing, go into the Unreal/System folder & open up OpenGlDrv.ini.
·
If you are using a TNT or other OpenGL based card change DoPrecache=1
to 0 if you want to disable precaching in OpenGL. This
will speed up the loading of levels, although may reduce
performance.
·
If you encounter any visual problems try changing UseMultiTexture=1 to 0.
This may adversely affect performance however.
·
Changing UseZTrick=1 to 0
can fix z-buffer related problems.
Rendering – S3 Metal support
In the case of S3 (Savage 3, 4 & 2000) users you
should use the S3 specific, Metal renderer. Savage 2000
owners will need to download
this patch
first & install it. Although this is intended for Unreal
Tournament, Unreal uses the same game engine so should
work just fine. To install it, backup your current metal.dll
& metaldrv.dll in the Unreal\System
directory & then place the downloaded metal.dll
& metaldrv.dll in the Unreal\System
directory, over-writing the old one.
Although if you decide not to use the directions
above (or have to revert to the backed up versions) your
options will be as follows. Either way, ignore the settings
that aren’t available.
Coronas.
Set this to True.
This is the haze of light that appears around light sources
in the game, such as lamps in the game. It has little effect
on performance.
Description.
This field displays the graphics card that you are using.
Not much use unless you have multiple video cards in your
system & want to check the correct one is being used in
Unreal Tournament.
DetailTextures.
A detail texture is a very small, fine pattern which is faded in as you
approach a surface, for example wood grain, or imperfections
in stone. Setting this to True will improve
visuals, although can adversely affect performance when set
to True. Set it to False for improved
performance at the cost of some visual quality.
DisableTrippleBuffering.
Set this to False for improved performance (Triple buffering allocates a 3rd
frame buffer. This frame buffer can improve performance by
allowing the hardware to render at the same time that the 3D
application performs other tasks), although it will
require extra video memory. Certainly set this to True
if you have less than 16MB of video memory on your graphics
card as this requires extra video memory.
Enable32BitZ.
This setting is set to False by default. If you are
experiencing flickering world surfaces
& similar visual corruption when running in 16-bit color set this to True.
This forces
the use of a 32-bit Z buffer (even in 16-bit colour) which
should fix these display errors if they are occurring. You
may ignore this setting if you experience no such errors or
are running in 32-bit color.
EnableFastFlashblend.
Set this to True to improve performance, setting it
to False will improve visual quality slightly.
HighDetailActors. Set this
to True for better visuals. Setting it to False will improve performance.
ShinySurfaces.
Shiny surfaces are the reflective surfaces in the game, e.g.
on
some floors you can see your (& others) reflections. Setting it to False
will improve your frame rate in such areas. I’d recommend
setting it to False.
VolumetricLighting.
Set this to True
for better visuals (effects like fog), although with lower
performance. Setting this to False
will result in a big frame rate increase. On most
graphics cards that have trouble running Unreal setting this
to False along with DetailTextures to False
will mean the difference between a playable & an unplayable
game.
Much like Glide,
you should have few
problems with this renderer at all.
