Black Mesa Necro Patch Released, Improving Performance, UI, Controller Support & Stability

25 Comments

Crowbar Collective has released the Necro Patch for its amazing Half-Life Remake, Black Mesa. According to the team, this update improves the game’s performance, UI, controller support and overall stability.

Going into more details, the Necro Update packs optimizations for the Vulkan API and UI. Enhancements have been also implemented for the New Renderer and New Post-Process systems, particularly noticeable in scenes featuring water. Therefore, the game will now run faster on more PC systems. Plus, the update unlocks the even higher graphics setting in options menu.

The sun and local lights will also now cast God Rays. Not only that but the blending quality of normal maps within 4-way blending is better than before. Additionally, the team has disabled CPU-based backface culling for Func_Brush models, as well as CSM for viewmodels for secondary cameras.

As said, Black Mesa will now be more stable than before. The Necro patch fixes cases where the game would crash on startup. It also fixes a crash in the first map of Interloper.

Another major improvement is regarding the game’s UI. Crowbar Collective was able to finally fix the UI flickering and artifacting. As such, you’ll now get a more stable image.

Like always, Steam will download this update the next time you launch its client. Below you can also find its complete changelog.

Key Updates
  • Improved performance of the game (Vulkan, UI optimization, New Renderer/New Post Post Process Optimization)
  • Fixed cases where game would crash on startup
  • Fixed UI flickering and artifacting
  • Fixed crash in the first map of Interloper that players were experiencing
  • Improved controller support using Steam Input
  • Fixed hitch when weapon decals are first applied to gun
  • Re-enabled weapon decals by default
Rendering/Performance
  • Ported the game to DXVK 2.3.1 (first launch option)
  • Performance enhancements have been implemented for the New Renderer and New Post-Process systems, particularly noticeable in scenes featuring water
  • Fixed moss shaders and direction control for both vertex lit shader and skin shader (for props with/without phong)
  • Fixed halflambert/warp/specwarp related problems across all the shaders
  • Unlocked the even higher graphics setting in options menu
  • The lighting quality settings in the New UI have been updated to reflect recent changes.
  • Monitors and refract views can now leverage the New Renderer features
  • God Rays support has been added for the sun and local lights
  • -Note: God Rays are intentionally turned off for monitors and reflection views
  • Improved the blending quality of normal maps within 4-way blending
  • SpotLight cookies should now work on any orientation. Cookie sprite sheet no longer needs to be square.
  • Black Mesa now requests high-performance power management on Windows, which should reduce power throttling impacting performance
  • Implemented the ability to dump environment variables (-dumpenvironment launch option), assisting in resolving potential issues
  • Lots of misc graphics fixes
  • Disabled CPU-based backface culling for Func_Brush models
  • Disabled CSM for viewmodels for secondary cameras
  • Fixed flicker near Light Volume edges
  • Fixed Xog artifacts with cheaper water
Controller Support

Controller support for Black Mesa has now been given the love and attention it has been seeking. Black Mesa now fully supports and integrates with Steam Input, allowing both us as developers and you as the community to create your own custom controller bindings and share them!

With Steam Input now implemented, we now have partial support the following devices:

  • Xbox Controllers
  • Playstation Controllers
  • Nintendo Switch Pro Controllers
  • We have also implemented proper Gyro support for Steam Deck!

To get started, simply navigate to the Steam Controller Layout configurator and select one of our official layouts and hit ‘Apply Layout’.

User Interface
  • Modified the Game/UI rendering synchronization, aiming for stable UI presentation across all three available modes
  • Updated the UI frame limiter logic to enhance the smoothness of frame pacing, which was particularly noticeable when vertical synchronization was active
  • Improved performance by optimizing the texture lock implementation within the UI
  • Resolved the issue where the UI occasionally failed to render at full size after resolution adjustments
  • Fixed alpha blending of UI with background map
  • Added a number of missing translators, including the 2012 mod translators (need to track down a list of who did what language)
Bug Fixes
  • Interloper A crash fix
  • Resolved the issue where the Tau Canon would crash upon the owner’s demise
  • Addressed a potential hang issue upon exiting the game
  • A reflection bug involving Xen fog at extreme angles has been fixed
  • Transparency issues in fake water have been resolved, and it now supports New Renderer, New Post-Process, and CSM
  • Resolved outline artifacts present in alpha-tested materials
  • Resolved an issue where view models were improperly identified within one shader, leading to lighting and shadow inconsistencies
  • Fixed a bug related to the Diffuse Warp when using more than eight slots in the atlas
  • Fixed a Workshop Client issue related to double initialization, which had the potential to cause crashes
Known Issues
  • Alt-Tabbing while using Vulkan can sometimes crash the game
  • Anti-virus can sometimes flag the game as malicious even though it is not (we’ll see what we can do about this)
  • Minor UI overlap errors on some ultra wide monitors
  • Some UI elements need localization
