Following our continuous work on expanding and perfecting the simulation, we want to thank everyone for your incredible dedication and the steady stream of constructive feedback.
Our team has been working tirelessly behind the scenes on a massive technical overhaul. In this Systems & Performance Update, we are thrilled to announce that Modern Naval Warfare has officially migrated to Unity 6.3 LTS, introducing a DirectX 12 baseline, support for Raytracing graphics effects, and modern upscaling features like DLSS and FSR. Furthermore, we are expanding our global reach by introducing official localization support for six new languages.
This update also overhauls core weapon control logic, refactors submarine mast exposure physics, and fixes a critical VRAM leak to heavily optimize performance during long play sessions.
Below is the complete list of fixes, features, and known issues included in today's build (0.118.8):
Fixed Issues
Engine, Performance & Graphics
Unity 6 Migration: Successfully migrated the project to Unity 6.3 LTS, establishing DX12 as the base for Windows (retaining DX11 compatibility) and enabling ultra-quality Raytracing effects.
Upscaler Support: Added integrated support for modern upscaling technologies, including NVIDIA DLSS and AMD FSR.
VRAM Optimization: Fixed a critical VRAM leak caused by rogue assets not unloading upon mission completion, drastically improving stability during long sessions.
Cinemachine Upgrade: Migrated Cinemachine to a fully Unity 6 compatible package.
Features & Localization
Expanded Language Support: Added official localization for English, German, French, Polish, Chinese, and Russian.
New Settings Options: Added toggles for Motion Blur, Underwater Blur, and a new setting to customize the transition speed between stations.
Input & Camera Controls: Migrated to the new Unity Input Manager and added options to invert the mouse Y-look axis (including specific controls for Photonics view).
User Data Migration: Implemented updated user migration mechanisms (MSV 0.117.0 / 0.118.0) to safely inject new settings without breaking older user profiles or save files.
Simulation & Weapon Control Overhaul
Advanced Weapon Control: Overhauled weapon depth/altitude control logic utilizing real-world PID systems, making torpedoes and guided systems significantly more accurate and lethal.
Mast Exposure Physics: Refactored the mast controller system to correct exposure tracking above water, fixing a serious issue where sensors malfunctioned at periscope depth or enemies failed to detect exposed masts.
Radar Mesh Improvements: Added new cached submarine meshes to vastly improve radar cross-section (RCS) detection of masts exposed over the water line.
Environmental Data (SSP): Introduced realistic seasonal GIS data interpolation and day-to-day temperature deviations, creating dynamic monthly ocean variations.
Advanced Radar Calculations: Improved Pulse Radar Line of Sight calculations using true earth curvature and optimized RCS tracking by factoring reflection areas against pulse wavelengths.
General Bug Fixes
Autopilot & Steering: Resolved a major issue where deleting a plotted route while the Autopilot was active would lock the system and ignore subsequent steering orders.
Navigation & UI: Fixed an issue where entering specific coordinate values in the ECDIS field rendered it unresponsive, and restored mouse scroll wheel functionality in the time compression UI area.
Sensor Fixes: Resolved a critical bug in the Aperture Calculator that caused sensors and NPCs to become unresponsive upon entering the Salma H mission. Fixed uncleaned station UI texts that caused blurry lettering when focusing.
Communications & Radar: Corrected radio antenna water exposure calculations that hindered underwater communications, and fixed a sync issue that delayed or prevented terrain rendering on the Radar screen.
Data Corrections: Fixed general AIS bugs where speeds were not correctly converted to knots, updated Torpedo status mapping methods to Enum, and formatted ESM values clearly into GHz.
Known Issues
We are actively tracking the following verified issues and are working on solutions for upcoming patches:
UI & Sonar: Active Intercept can register the same contact multiple times if the contact operates on a very low Pulse Repetition Frequency (PRF). HF Sonar Bearing/Range numbers are temporarily missing, and explosion sounds are currently not registering on SONAR displays.
Visuals & Customization: Ship names currently do not print on hulls during gameplay due to a name-assigner shader issue, and names may fail to assign properly after loading a save.
Upscaler Artifacts: Setting upscalers (DLSS/FSR) to high-performance modes can cause station UI text to appear slightly blurry.
Physics & Anomalies: We are monitoring a rare, low-frequency physics loop-breaking issue causing visual anomalies ("flying whales"), though it is expected to be largely resolved.
Upcoming Languages: Work is ongoing to complete official localization support for Spanish, Greek, and Romanian in a future update.
Moving Forward
Our commitment to expanding and perfecting Modern Naval Warfare remains our top priority. We are continuously monitoring your feedback as we polish core features and move forward towards future updates.
