• Download SwiftShader from here
• Extract the contents into a folder.
• Copy d3d8.dll, d3d9.dll and swiftshader.ini from the folder into the folder where the game executables are located (usually in theinstallation directory, but if your installation directory is empty, check the subfolders inside; they usuallyare in the subfolder 'bin')

• Open up swiftshader.ini with notepad or wordpad, and edit the options as needed. Here is a rundown of what options are there:

[Capabilities]
PixelShaderVersion=2
>> - defines
maximum pixel
shader version, e.g. 21
= 2.1, 20 = 2.0, 10 =
1.0
VertexShaderVersion=
>> - defines maximum
vertex shader version,
e.g. 21 = 2.1, 20 = 2.0,
10 = 1.0
TextureMemory=512
>> - defines texture
memory, if games run
too slow, try changing
to 1024 (only if you
have 1GB of RAM)
[Caches]
VertexRoutineCacheSi
>> - According to your
available RAM
PixelRoutineCacheSize
>> - According to
your available RAM
SetupRoutineCacheSiz
>> - According to your
available RAM
VertexCacheSize=64
>> - 1/8 of the
Available RAM
[Quality]
TextureSampleQuality
>> - don't touch it,
lowering sample
quality will not
improve performance
MipmapQuality=0
>> - it defaults at 0, so
don't touch it
PerspectiveQuality=2
>> - 0 Disable, 1
Normal, 2 High. The
higher the value the
higher required
resources
TranscendentalPrecisi
- 0 Disable, 1 Normal,
2 High. The higher
value the
higher required
resources
[Processor]
ThreadCount=0 >>
- change to 2 if you
have dual core, 4 for
quad core, or leave it
at 1 for single core
CPUs
EnableSSE2=1 >> -
0 = disabled, 1 =
enabled, leave it
enabled
EnableSSE3=1 >> -
0 = disabled, 1 =
enabled, leave it
enabled
EnableSSSE3=1 >> -
0 = disabled, 1 =
enabled, leave it
enabled

•  Run the game! If it's an old game, it should run smooth. Newer games usually run at choppy rates, usually unplayable but still you can play.
