FPS BOOSTER – CPU & AI LITE

Boost Your Hearts of Iron IV Performance with FPS Booster – CPU & AI Lite

Are you experiencing crippling late-game lag in Hearts of Iron IV that grinds your strategic simulations to a halt? The FPS Booster – CPU & AI Lite mod is engineered to breathe new life into your campaigns, offering significant performance enhancements without altering the core visual experience of the game. This lite version focuses on optimizing the simulation’s backbone, ensuring a smoother, faster, and more enjoyable Hearts of Iron IV experience, especially when the world map becomes crowded and complex.

Core Performance Enhancements

This mod achieves its performance gains by intelligently adjusting the frequency of AI calculations and reducing data bloat. The AI, often a significant drain on resources, has its decision-making intervals spaced out across various aspects of gameplay. This includes trade, diplomacy, template design, doctrine evaluation, and equipment refits.

Key Features for a Smoother Game:

• Optimized AI Intervals: Trade and diplomacy checks are extended from daily to every 96 hours. Division template and equipment refit checks are expanded from weekly to monthly intervals. Naval refits are adjusted from near-monthly to quarterly checks.
• Reduced Save Bloat: Obsolete AI templates are purged from memory after 90 days, and various logs are periodically cleared, significantly reducing save file size and loading times.
• Streamlined Pathfinding: Naval target recalculations and strike force checks are performed weekly, and AI raid target evaluations are reduced per hour, freeing up CPU resources.
• Visual Air Combat Optimization: The only visual change is the significant reduction in air combat models, where one 3D model now represents hundreds of planes. This directly combats the infamous late-game airzone lag without touching map graphics.

Unrivaled Compatibility

Designed with an additive architecture, FPS Booster – CPU & AI Lite acts as a “ghost” optimization patch. It does not modify core game files, making it exceptionally compatible with a vast array of other Hearts of Iron IV modifications. This includes seamless integration with major total conversion mods like The New Order, Kaiserreich, and Road to 56, as well as other optimization mods. When combined with other optimization tools, you can achieve the maximum possible performance boost.

Important Note: Due to changes in core AI logic, this mod alters the game’s checksum. All players in a multiplayer session must have this mod installed. It is not compatible with Ironman or achievement runs.
