The System Pack correctly implements QueryPerformanceCounter and Sleep timers. It caps the game’s logic loop without capping the render FPS. Result? Zero hitching, zero loading lock-ups.

It is the DX11 Renderer . That is a separate visual enhancement. The System pack works alongside the DX11 renderer, but you can use it alone. It is not a gameplay mod (like L'Hiver or Atariar ), so your save files remain vanilla compatible.
