While some people have FPS and low game issues, I have the exact opposite.

When I started to play, after raging about the really weird sensitivity, the ennemies was like under coke, but i said "Ok, maybe it's like in Max Payne, the normal difficulty is just impossible, so go on easy...". Then, When I came up to the cinematic of the second level, it was skipping every dialogues, so I was telling me "maybe it's just cinematic bugs, afterall I don't care about the story". But then, I heard the footsteps. It was like Caleb was running 196km/h, because actually, the game is OVERACCELERATED. That's why the sensitivity was either with a sort of acceleration or a negative acceleration...

I play, I don't know, maybe 2x speeder. XD

Is there any way to fix this? :(

(I already enabled the triple buffering, no change)

Solution: It wasn't the game this time, but my video card options. If you have the same problem, maybe you have the Thread Optimisation disabled or the V-Sync completely disabled, in the parameters of your video card.
For Nvidia users, got to the Nviia control panel, and in " 3D Settings ", then scroll to find what you want.
