This file overrides the engine's core rendering pipeline. It disables dynamic shadows entirely and limits the game to only using 2 CPU cores (preventing CPU bottleneck on Celeron/Pentium chips). Set to 0
Optimizing for a low-end PC requires a combination of manual configuration file tweaks and system-level adjustments to bypass the game's standard graphical limits. By modifying internal parameters and managing how your hardware handles the Frostbite engine, you can achieve a playable frame rate even on hardware that falls below the official minimum requirements.
