What's new in TDM 2.06

Version 2.06 of The Dark Mod has not been released yet.

See the roadmap on our bugtracker.

The Dark Mod 2.06 is a major step forward!

It is the first TDM release to offer a native 64-bit build with EFX sound support for all OpenAL compliant hardware.

It is also the first TDM release to offer true Multi-Core support via patches from Cabalistic's VR branch.

Another first? This is the first TDM release to offer Video Codec support other than ROQ via FFMPEG.

Now briefing videos and cut-scenes can be better looking than ever.

A substantial amount of work was done to replace legacy OpenGL methods with their equivalents in modern OpenGL.

The Mission browsing experience via smooth Scrolling GUI Menus.

GUI scaling menu options now exist and there is a visual preview area to test your scaling settings.

Some initial support for Security Cameras has been implemented.

Finally, Duzenko and Stgatilov have implemented an Experimental Soft Shadows option

which has some distance based softening and anisotropic sampling correction!!!

(Some prior Soft Shadow research and implementation was borrowed or approximated

from SteveL's old Soft Shadow code for 2.04 era development builds.)

Cvars:

• com_smp 1: allows the frontend and backend to run on different threads. same as the multi-core enhancement option in the GUI
• com_fixedTic 1: uncapped FPS ( really capped at 166hz to prevent audio bugs, etc. )
• r_useGLSL 1: Enables the GLSL backend. Is automatically enabled when enabling Soft Shadows
• r_useFBO 1: Enables Frame Buffer Objects. Uses less fillrate and allows for new rendering options
• r_fboSharedDepth 1: Read and Write to the Depth buffer in a feedback loop setup. Offers a big performance boost for Intel GPU's
• r_fboSharedColor 1: Read and Write to the Color buffer in a feedback loop setup. Offers a big performance boost for Intel GPU's (do not use on Nvidia).
• r_fboResolution: Multiplies your native resolution times your input value. 2 means double resolution. Works like SSAA. Very high performance cost.
• r_fboColorBits: Set either 16 or 32 bit color
• r_useMapBufferRange 1: Improves VBO performance. Some render artifacts if you enable this with com_smp and lightgem interleave.
• r_useBfgPortalCulling 1: AnonReclaimer's port of culling code from Doom 3 BFG. Improves cache behavior and is meant to be paired with com_smp and r_useMapBufferRange.
• r_cinematic_legacyRoq 1: Decode ROQ videos with old Doom 3 code rather than FFMPEG. It may improve performance for some users.

• r_softshadowsradius: Determines how large the light center is for light sources. Larger values soften shadows more.
• r_softshadowsquality: Determines how many gradients for shadows. Larger values produce smoother blending at more performance cost.
• r_shadowPolygonFactor: Set to 1 to reduce light leak artifacts in Shadows.
• r_nvidiaOverride 1: forces r_useFBO if you have nvidia hardware and soft shadows enabled

Toggling Creep!

You can now setup a key bind for toggling creep.

To use you must define a toggle in Darkmod.cfg

bind "<preferred key>" "toggle tdm_toggle_creep 0 1"

replace <preferred key> with whatever key you wish.

If you want to use CTRL, you will need to remove:

bind "CTRL" "_button5"

Old TDM Look

If you have older hardware that doesn't work well with GLSL or just wish to have things look as they did in TDM 2.05 simply set these cvar values:

• r_nvidiaOverride 0
• r_softShadowsQuality 0
• r_useFBO 0
• r_useGLSL 0

Experimental Soft Shadows, Anti-Aliasing, FBO and You.

The current Soft Shadows method has some rendering bugs (flickering artifacts on noSelfShadows objects)

for some hardware vendors (Nvidia is the main one) when Frame Buffer Objects are not used (r_useFBO 0).

For this reason the r_nvidiaOverride cvar forces r_useFBO on when Soft Shadows are enabled and the vendor is Nvidia.

However, enabling r_useFBO completely disables MSAA so we've converted AA settings

to resolution scaling values r_fboResolution to approximate SSAA.

You can also use resolution scaling (see workaround 3 below).

Enabling r_useFBO will also cause glass or transparent materials to render strange discontinuities.

They are generally not easy to see but may annoy you. It's a choice between artifacts but

the shadow flickering on noSelfShadows surfaces is far more of a visual bug

than the discontinuities in transparent materials

Here are the workarounds for this issue:

• 1) Increase resolution to where AA is not needed
• 2) Use Resolution Scaling (DSR) in your video driver and set TDM resolution higher than your native resolution
• 3) Use in-game resolution scaling via r_useFBO 1 and GUI AA settings (see below).

Note: when r_useFBO is enabled along with r_nvidiaOverride, the AA settings in the GUI are converted
to r_fboResolution scaling values to approximate SSAA. So you wont necessarily need to
play with console variables (cvars) and you can instead just use the AA settings in the GUI.

Be forewarned that not every setting will be ideal for every monitor resolution so if you wish to tweak this
behavior and choose your own scaling multiplier disable r_nvidiaOverride and set r_fboResolution to your preferred value.

Experiment with r_fboResolution values between 1.05 and 2.55 to see what looks best.

( 1.25, 1.5, 1.75, and 2.0 are sweet spots for resolution scaling since its simple bi-linear scaling. ) 

If you use this AA method, you may see some skyboxes with bright artifacts. This only affects a few missions
that use the Portal Sky feature. 

• 4) Disable in-game AA and set SSAA in your driver settings also set r_useFBO 1.
• 5) Disable in-game AA, set FXAA, SMAA or MLAA in your driver settings also set r_useFBO 1. (best performance)

TDM 2.07 (SVN unstable) currently has MSAA support with FBO so much of the above is already resolved.
