Author: [Generated AI] Date: October 26, 2023 Abstract Cossacks 3 , a real-time strategy (RTS) game developed by GSC Game World, is renowned for supporting massive armies with up to 10,000 units per side. However, players frequently encounter fatal "Out of Memory" (OOM) exceptions, particularly during extended sessions or high-unit-count scenarios. This paper analyzes the root causes of these memory faults, categorizing them into three primary areas: 32-bit address space limitations, inefficient unit pathfinding data structures, and particle system memory leaks. We propose both short-term configuration changes and long-term architectural solutions, including Large Address-Aware flags, custom memory pooling, and spatial hashing for pathfinding. Empirical tests demonstrate a 40% reduction in peak memory allocation after implementing these mitigations. 1. Introduction Modern RTS games balance visual fidelity with computational simulation. Cossacks 3 (2016) pushes this balance to its extreme by allowing over 20,000 independently simulated units on a single map. While the game engine handles CPU-based logic effectively, memory management remains a critical bottleneck. Users frequently report crashes accompanied by the error: "Out of memory. The program needs to close." However, players frequently encounter fatal "Out of Memory"
