SwiftShader tries to emulate full graphic processes such as pixel shader support, floating, rendering, stenciling and more. It can therefore be used to try and run some games with which 3D Analyzer does not solve the problem.
1. Download SwiftShader, you can get it from the 'Downloads' section.
2. Extract the contents into a temporary folder.
3. Copy d3d8.dll, d3d9.dll and swiftshader.ini from the temporary folder into the folder where the game's executables are located
(usually in the installation directory, but if your installation directory is empty, check the subfolders inside; they usually are in the
subfolder 'bin')
4. 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=21 >> - defines maximum pixel shader version, e.g. 21 = 2.1, 20 = 2.0, 10 = 1.0
VertexShaderVersion=21 >> - 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]
VertexRoutineCacheSize=1024 >> - don't touch these
PixelRoutineCacheSize=1024 >> - don't touch these
SetupRoutineCacheSize=1024 >> - don't touch these
VertexCacheSize=64 >> - if games run too slow, change it to 128, any higher will make the game even slower
[Quality]
TextureSampleQuality=1 >> - don't touch it, lowering sample quality will not improve performance
MipmapQuality=0 >> - it defaults at 0, so don't touch it
PerspectiveQuality=2 >> - don't touch
TranscendentalPrecision=2 >> - don't touch
[Processor]
ThreadCount=0 >> - change to 2 if you have dual core, 4 for quad core, or leave it at 0 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
5. Run the game! If it's an old game, it should run smooth. Newer games usually run at choppy rates, usually unplayable. Have
fun!
