I wrote up a setting guide in the Torrent File. I'll post it here for convenience.
[OpenGLDrv.OpenGLRenderDevice]
TruFormMinVertices=0 <- ATI TruForm cards only. Disabled in Renderer.
TruFormTessellation=3 <- ATI TruForm cards only. Disabled in Renderer.
UseTruForm=False <- ATI TruForm cards only. Disabled in Renderer.
ZRangeHack=True <- Apparently something to do with Z Buffers. If it causes problems, try setting it to False to fix.
AAFilterHint=2 <- Set this to 0 unless you have a nvidia card (Quincunx AA)
NumAASamples=0 <- Antialiasing. Usually a Power of 2 - 2, 4, 8, etc. Using Numbers your card can't do is a bad idea.
UseAA=True <-- Toggles Antialiasing. True means it's on, False means it's off.
RequestHighResolutionZ=False <- Set this to true if you're in 16 bit color, False if you're in 32 Bit Color
MaskedTextureHack=False <- Should be False.
FrameRateLimit=0 <- If the game is Too Fast when you're moving towards walls, Change this to another value. 200 will work.
SwapInterval=0 <- Set to 0 for no vsync, 1 to enable it. -1 for Autodetect.
UseVertexProgram=False <- Keep this False.
UseCVA=False <- Set this to true if your card is VERY old, without Hardware T&L. Keep False if your card has Hardware T&L.
UseMultiDrawArrays=True <- Enables the use of the GL_EXT_multi_draw_arrays extension.
TexDXT1ToDXT3=False <-Set to True for Older (GeForce 1-4) NVIDIA cards, otherwise, keep False.
DynamicTexIdRecycleLevel=100 <-- Keep at 100.
CacheStaticMaps=False <- Unknown. Keep False.
UseTexPool=True <- Keep True.
UseTexIdPool=True <- Keep True.
UseSSE=True <- Nearly all CPUs, and all since 1999 or so, will have SSE. Keep True unless your system is Ancient.
BufferTileQuads=True <- Enables buffering in the DrawTile path. May improve text rendering performance.
BufferClippedActorTris=False <- Shouldn't be worth turning to True, but if you got odd clipping issues, try it.
SinglePassDetail=False <- Attempts to Render textures in one pass. Won't work if DetailMax is higher than 1.
SinglePassFog=True <- Enables High-Quality Fog. Needs GL_ATI_texture_env_combine3 extension or GL_NV_texture_env_combine4.
ColorizeDetailTextures=False <- Keep False.
DetailClipping=False <- Should be fine False, but it might speed things up on fillrate-crippled machines.
UseDetailAlpha=True <- Must be True for Detail Textures to work.
DetailMax=2 <- 0 for none, 1 for One Layer of Detail, 2 for Two Layers. Any more isn't noticeable and will slow the game.
RefreshRate=0 <-Set to highest refresh rate your monitor supports (ex: 85) Default if set to 0.
MaxTMUnits=0 <- Debug Option. Keep at 0.
NoFiltering=False <- Debug Option. Keep False.
NoMaskedS3TC=False <- Keep False unless you want to see how a S3TC texture looks on older hardware.
MaxAnisotropy=0 <-Set to Anistropy Level. 0 to Disable, 2, 4, 8, 16 to use higher levels of AF.
UseTNT=False <- True if you have a old TNT or TNT2 Card.
Use16BitTextures=False <- Less Colorful, but Smaller Textures. Keep False in most cases.
UseS3TC=True <- Set to true if you use the S3TC textures.
UseAlphaPalette=True <- Keep True unless you have old, Buggy GeForce Drivers.
AutoGenerateMipmaps=False <- Generate Mipmaps for textures lacking them, but might slow things down. Keep False.
UseTrilinear=True <- Enable Trilinear Filtering. False to Disable.
UsePrecache=True <- Precache Textures. True will reduce stutters in-game, but increase load times.
AlwaysMipmap=False <- Disabled in Game Code, Keep False.
ShareLists=False <- Unknown, keep False.
UsePalette=True <- Enables Paletted Txtures if your card can do them. Set to False if you get problems.
UseMultiTexture=True <- Keep True for Renderer to work properly.
UseBGRATextures=True <- Enables slightly faster uploads if your card can upload in BGRA Format.
UseZTrick=False <- True may solve problems like the Redeemer clipping the Status Bar and the like.
MaxLogTextureSize=8 <- Leave as-is.
MinLogTextureSize=0 <- Leave as-is.
MaxLogVOverU=8 <- Leave as-is.
MaxLogUOverV=8 <- Leave as-is.
OneXBlending=False <- Emulates Direct3D Lighting Mode if True. Most people will keep this False.
GammaCorrectScreenshots=True <- Screenshots might be too dark if False, but if they're too bright, set it to False
GammaOffsetBlue=0.000000 <- Leave as-is.
GammaOffsetGreen=0.000000 <- Leave as-is.
GammaOffsetRed=0.000000 <- Leave as-is.
GammaOffset=0.000000 <- Leave as-is.
LODBias=0.000000 <- Negative values to sharpen textures. (ex: -1.5) Looks bad with S3TC on, keep at 0 if you're using them.
DetailTextures=True <- Enables Detail Textures, like Fine Grain on Wood. Keep True for more realism.
DescFlags=0 <- Leave at 0.
Description=NVIDIA GeForce FX 7800 <- Put your graphics card's name here if you want to
HighDetailActors=True <- Should always be True
Coronas=True <- True to turn them on, False to turn them off
ShinySurfaces=True <- True for reflective Surfaces (Like the Mirror in DM-Oblivion), False for no Reflections.
VolumetricLighting=True <- True for more realistic lighting.
I'll post the Torrent File itself here. PLEASE NOTE THIS IS JUST THE TORRENT FILE.
