If you want a solution without modifying game files, you can make the "out of memory" error work by reducing demand. Navigate to Settings > Graphics and apply these changes:
"I am the memory leak. The ghost of every polygon you forced to exist. You want your battle? I need a sacrifice. Not RAM. A piece of your linear time. Give me three seconds of your life. Permanently."

This crash often happens during intense, long-running matches, especially when playing on large maps with huge armies. Despite the game’s 3D engine, it is designed to run efficiently, but it frequently fails to manage memory allocation properly, leading to a sudden crash to desktop (CTD) just as the battle reaches its peak.

The "Out of Memory" error in usually occurs because the game's engine struggles with modern high-resolution textures or reaches its 32-bit memory limit during long sessions with many units.
The game loads many high‑resolution sprites (not 3D models). Under extended play or after alt‑tabbing, texture data may not be released properly, filling both RAM and GPU VRAM. When VRAM fills, the system falls back to shared system memory, increasing pressure on the 32‑bit address space.
You only need to do this once.
