Prototype 2 on PC platforms is notoriously known for "micro-stuttering" and severe frame rate drops, even on high-end modern hardware. The community has identified the root cause as the game's inability to properly utilize modern multi-core CPU architectures (specifically handling more than 2-4 threads) and inefficient streaming of texture data.
Key Issues to Address:
On an RTX 3060 + i5-12400F:
| Scenario | Vanilla (Uncapped) | After Fix #1+2+4 | | :--- | :--- | :--- | | Gliding in Red Zone | 22 FPS (Slow motion) | 60 FPS (Smooth) | | Hive Explosion | 15 FPS freeze | 58 FPS | | Input lag | 180ms | 35ms | prototype 2 lag fix work
Before we dive into the fixes, it helps to understand why this game stutters. Prototype 2 was built during the transition from DirectX 9 to DirectX 11. It was optimized for dual-core CPUs and older graphics architectures. Prototype 2 on PC platforms is notoriously known
