Note: From Portal, but will be the same for majority of Source 2013 Singleplayer games (running on HL2 20th Anniversary Update build). This includes Half-Life 2 (and it's episodes), Half-Life: Source (both since November 16, 2024) and Portal (May 20, 2025 update).

Note: Differences from Portal 2's printed mat_info with previous Source branches (Orange Box series - includes Source 2007 to Source 2013, and Team Fortress 2 branch):

Added

"Display mode" now lists refresh rate.

• "m_NumVertexSamplers"
• "m_bPreferZPrepass"
• "m_bSuppressPixelShaderCentroidHackFixup"
• "m_bPreferTexturesInHWMemory"
• "m_bPreferHardwareSync"
• "m_bUnsupported"

Changed

• "m_bNeedsATICentroidHack" - was set to "no", atleast on a Nvidia GPUs (on Orange Box this was set to "yes", even though this was intended for ATI/AMD Radeon GPUs).
• "m_nDXSupportLevel: 100" - in L4D branch and above (except CS:GO), mat_dxlevel was set to 100 (atleast confirmed to be used on PC with modern DX10 or later GPUs like GeForce 8 series), but the game still uses Direct3D 9 for rendering. Other Source games would max this out at 95.

Removed

• "Max Stages : (x)"
• "m_NumTextureStages"
• "m_SupportsPixelShaders(1.1, _1_4, _2_0)" (detects if the GPU support Pixel Shader 2.0 or earlier. Detection for Pixel Shader 2.0 or earlier was removed, but Pixel Shader 2.0b detection is still present.)
• "m_SupportsVertexShaders" (Source still support Vertex shaders but this detection was unnecessary for branches that was designed to support full DX9 GPU only (which all supports it) so it has been removed)
• "m_SupportsMipmapping"
• "m_SupportsOverbright"
• "m_SupportsCubeMaps"
• "m_SupportsHardwareLighting"
• "m_MaxBlendMatrices"
• "m_MaxBlendMatrixIndices"
• "m_SupportsNonPow2Textures" (checks if the GPU supports non-power-of-two textures)
• "m_HasProjectedBumpEnv"
• "m_bSupportsSpheremapping"
• "m_bColorOnSecondStream"
