FPSLimitOverride = 30 (On very low-end PCs, locking the game to 30 FPS provides a much smoother experience than an unstable 60 FPS). 3. CPU Core Management (The Affinity Fix)
Reducing the resolution is the single most effective way to gain FPS on integrated graphics or older GPUs. 2. Prototype 2 Fix (Essential Optimization Mod)

The community created a specialized mod called that acts as a dynamic configuration tool. This fix addresses engine-level bottlenecks that a standard config file can't reach.
CustomResolution = 1 (Allows you to set a resolution lower than the game’s standard menu options). For players on low-end systems
Since there isn't a text file to edit, you can force the game to run at lower, non-standard resolutions to save resources.
Prototype 2 is notorious for being poorly optimized on PC, often suffering from stuttering and low frame rates even on modern hardware. For players on low-end systems, there is no traditional config.ini file in the game's directory that allows you to lower graphics settings beyond what's available in-game. Instead, achieving a playable experience requires a combination of community-made , launch arguments , and external optimization tools . 1. The "Hidden" Config: Use Launch Arguments
Prototype 2 often crashes or lags on CPUs with more than 8 threads because the engine struggles with modern multi-core architecture.
