If that happens, disable the overlay in the game properties in Origin. *The Origin version might crash on start when the ingame overlay is enabled. Older versions or ones that otherwise have been tempered with might not work. Important: This fix relies on the latest, fully patched executables of the supported versions. This is because the game applies calculations based on the momentum of the player character to the input. Note: Although the input is pretty raw when aiming, it may still feel a little bit sluggish when moving and turning the camera at the same time. Simple installation and usage without any external configuration.Configuration via the ingame settings as usual.No additional smoothing or positive/negative mouse acceleration.Raw mouse input independent of FPS or VSync.DOOM - it should be a huge improvement to the default behavior. While the movement is still not as perfect as in other games - e.g. This fix attempts to circumvent those problems by acquiring raw mouse input and injecting it directly into the game's camera functions, making the controls as independent of the frame rate as possible. Unfortunately, this also means that playing at higher frame rates is often not feasible, which also prevents users from taking advantage of GSync, FreeSync, Fast Sync or similar technologies. This is why popular workarounds recommend to disable V-Sync and cap the frame rate to avoid fluctuations. The problem gets worse when activating V-Sync. This leads to movement that is generally better when the frame rate ist stable. This is because the engine applies a lot of transformations to the input that are based on frame time. While many players report issues with positive or negative mouse acceleration or overall sluggish movement, others state that the controls are not that bad. The mouse controls in Dead Space are notorious.

It works with VSync and high frame rates and is easy to install without having to fiddle around with FPS limiters or config files. This fix makes Dead Space use raw mouse input without any additional smoothing or acceleration.
