What changed in Black Mesa in 2025

Major overhaul of Focal Point with improved lighting, performance, combat, and atmosphere.

More autosaves added to improve gameplay experience.

A ton of bug fixes and polish included in the update.

A new scene at the end of Focal Point that smoothly transitions into Power Struggle.

Open playtest for Rogue Point running from November 20–24.

Addition of new voice lines and refined audio for a better experience.

Upgraded visuals, models, and textures across the board, enhancing the game's world.

Resolved a rare issue that prevented the game from launching and triggered a 'Failed to load the Launcher DLL' error in specific scenarios.

New DLL directory resolution functions are now enabled by default for improved security and compatibility.

Fixed grenade fuse continuing after the owner's death in multiplayer matches.

Fixed incorrect animation state when unarmed in multiplayer.

Updated DXVK (Windows) to version 2.6.2.

Significantly improved Parallax Occlusion Mapping (POM) quality in applicable materials.

Scales inherited velocity by mass ratio and biases resolution based on contact direction.

Ensures hierarchy-correct traversal by sorting bones by tree depth before applying fixes.

Uses trace normals and parent-to-child constraints to reposition bones without excessive separation.

Bundled a minimal set of required runtime dependencies from Microsoft Visual Studio and DirectX.

Fixed normal mapping issues related to the dynamic lighting on Brush-based geometry.

Added support for the -disablenewdlldirectoryfunctions flag to disable SetDefaultDllDirectories and related APIs.

Enabled Parallax Occlusion Mapping (POM) functionality in ToGL.

Added -enableprocesspowerthrottlingstate flag to control process power throttling state.

Replaced old bone separation logic for ragdolls with a trace-based solver that resolves occluded or embedded bones.

Added debug overlay (r_debug_ragdoll_separation_solver) for visualizing correction passes.

Fixes crashes when resuming from a save file, potentially safeguarding other chapters.

For improved stability

By introducing coordinate sanitization in key areas

With that of the Prop GBuffer shader for consistency

Optimizing performance for multithreaded tasks

After the Secondary Camera fix

To improve shadow precision on ToGL

To prevent excessive speeds during explosions

For improved consistency across Intel, AMD, and NVIDIA

Using the updated Studio Model Compiler to prevent visual glitches caused by incorrect or outdated tangent data

Enhancing overall performance in scenarios featuring moving ropes, particularly during the rocket elevator sequence in 'On A Rail.'

Ensuring all materials are well-formed and error-free within the Material System

Especially noticeable on ToGL

Increased vertex buffer limits to match those defined in the original model format

By reviewing and fixing cases of unsafe use of short-lived data

Ensuring props are marked as non-statically lit if the static lighting checksum does not match

Resolved various graphical issues in Studio MDL models

Resulting in improvements in several areas, resolving sporadic crashing experienced by players in previous beta tests.

For improved tool compatibility

Entities would unexpectedly stop spinning after a certain amount of time on some maps

To prevent instant ground collision

To align Intel/AMD GPUs with NVIDIA, ensuring the game launches at 1080p by default

Occurred at the end of the Gargantua chase in the Surface Tension chapter

Especially when auto-configuration clashes with cloud-synced settings

To improve accuracy and consistency

Addressing visual inconsistencies

Ensuring that every installation reconfigures itself on the first launch after an update.

Lifting the previous global limit

According to VirusTotal

Updated auto-config version

Due to concurrent exclusive access to the internal game save file during gameplay

Where all surfaces were forcibly marked as bump-mapped

For smoother player interaction

On brush models

Now enabled by default, resulting in faster load times after the first run

Using the newer Studio Model Compiler to resolve tangent-related issues and improve visual fidelity

To prevent certain startup crashes with DXVK

With noticeable gains in the Lambda Core teleport puzzle

Without enabling unsupported features

Call to action is now present at the main menu.

Ensured all materials are well-formed and error-free within the Material System.

Secondary camera views were rendering incorrectly on brush models.

Improved accuracy and consistency.

Improved consistency across Intel, AMD, and NVIDIA GPUs.

All surfaces were forcibly marked as bump-mapped to reduce shader combinations.

Improved logic for configuration overrides, especially with cloud-synced settings.

Shadow Quality Mode can now be set to Ultra without enabling unsupported features.

Smoother player interaction with pickup and run mechanics.

All false positive virus reports according to VirusTotal have been removed.

Issue occurred in ToGL.

Now enabled by default, resulting in faster load times after the first run.

Artifacts were especially noticeable on ToGL.

Improved shadow precision on ToGL.
