This SFSE plugin automatically launches Starfield with High CPU priority, giving your game a noticeable performance boost. Not only does it increase process priority, but it also optimizes background operations, ensuring smooth gameplay even with a large number of mods.
Compatibility: Works with any SFSE plugin and is easy to install via Vortex or Mod Organizer 2 – just like any standard SFSE plugin.
Benefits:
Boosts FPS and reduces lag under heavy CPU load
Optimizes the game process without any extra configuration
Simple installation and full mod compatibility
Unlock the full potential of your PC and enjoy Starfield without compromise!
Requires:
Starfield Script Extender (SFSE) – MUST
Visual C++ Redistributable for Visual Studio 2019-2022
Changelog:
Version 1.1.2
Automatic CPU detection added; plugin adjusts behavior based on the detected CPU.
X3D CPU detection — some features will be automatically disabled on X3D models for full compatibility.
Plugin fully compatible with all modern CPUs supported by Starfield.
Log file added for clarity.
Improved memory workload handling and thread management.
Better process priority and affinity setup.
Enhanced error handling and general stability improvements.
Version 1.0b
Maintains high CPU priority and full core usage.
Fully compatible with SFSE 0.2.17.
Note: This version is intended for players who have not yet updated to the latest Starfield version.
Version 1.0.9.1
Added FOMOD installer for full MO2 and Vortex compatibility
Minor fixes in code logic
Small optimizations for smoother performance
Corrected minor bugs noticed in previous version
General stability improvements
CPU Build Options in FOMOD:
SSE2 Build → Safe fallback for older CPUs (pre-2013 Intel/AMD)
AVX2 Build (Recommended) → Standard for almost all modern CPUs:
AMD: Ryzen 2000, 3000, 5000 series (and newer)
Intel: 6th Gen (Skylake) up to current
AVX-512 Build → Supported on newer Intel and AMD CPUs with AVX-512:
Intel: Ice Lake, Rocket Lake, Alder Lake (certain models), Sapphire Rapids and newer
AMD: Ryzen 7000 series (Zen 4 architecture) and newer
Version 1.0.9
Added FOMOD installer for full MO2 and Vortex compatibility
Minor fixes in code logic
Small optimizations for smoother performance
Corrected minor bugs noticed in previous version
General stability improvements
CPU Build Options in FOMOD:
SSE2 Build → Safe fallback for older CPUs (pre-2013 Intel/AMD).
AVX2 Build (Recommended) → Standard for almost all modern CPUs:
AMD Ryzen 2000, 3000, 5000, 7000 series (and newer)
Intel 6th Gen (Skylake) up to current
AVX-512 Build → Only for newer Intel CPUs with AVX-512 support (e.g., Ice Lake, Alder Lake certain models).
⚠️ Not supported on AMD Ryzen CPUs.
Version 1.0.7
Replaced the single high-priority thread with a ThreadPool implementation for multiple workload threads.
Each thread now uses Starfield’s MemoryManager for memory allocation, reducing CPU overhead and memory fragmentation.
All plugin allocations are now game-native (no malloc/new), improving stability and performance.
CPU affinity and thread priority improved – threads now use THREAD_PRIORITY_HIGHEST across all cores.
Reduced occasional lag spikes during plugin initialization.
Improved compatibility with SFSE 0.2.18 and Starfield version 1.15.222.
Version 1.0b
Almost the entire functionality of 1.0.6 has been ported to be compatible with Starfield 1.15.216.
Maintains high CPU priority and full core usage.
Optimizations for smoother gameplay and better performance with heavy mod setups are preserved.
Fully compatible with SFSE 0.2.17.
Note: This version is intended for players who have not yet updated to the latest Starfield version.
Version 1.0.6
New Features
High CPU Priority – Starfield now automatically runs in high priority mode, giving smoother performance and better CPU allocation.
Full CPU Core Utilization – The plugin now ensures the game can use all available CPU cores, maximizing performance.
Direct Launch from DLL – Removed the dependency on an external batch file; everything runs directly from the DLL.
⏱ Improvements
Startup Delay – Added a small delay before setting high priority, ensuring compatibility with Starfield’s initialization sequence.
Stability Enhancements – Minor improvements in thread handling and process management to prevent crashes during early game startup.
Bug Fixes
Fixed issues with launching high priority on systems with multiple cores.
Fixed string conversion issues for process names (Unicode vs ASCII).
Notes
Requires SFSE 0.2.18 for compatibility.
Works on all CPUs supporting SSE2.
No additional configuration is required from the user; just load the DLL.
Version 1.0.4
Improved CPU compatibility
Fixed a critical issue thanks to LostInWhere and some great tips from the community!
