Game Input MultipleXer

Hi,
firstly, I wanted to say Gimx is very very good and working well with my ps3 . But I have a few small issue.

1) Why do I feel a little bit shaky or jittery (sometimes*) when I play with my mouse?
2) Does this got to do with my Logitech mouse DPI (I think it's 800+)? Because my mouse is cheap but I can play fps games with it on my pc.
3) When I use the keyboard and mouse for Black Ops 2, does the 'Target Assist' work correctly?

Lastly, I would like to say THANK YOU to the Gimx developers, the program is free and working very good even though I'm using the 0.5 version.

Additional Information :
Ubuntu 11.1
Gimx 0.5
Mouse DPI should be 800

Hi,

Quote from the wiki:

GIMX can decelerate mouse movements so as to counteract the in-game acceleration.
A high DPI mouse gives a better linearity (i.e. smoother movements) in this specific case.

While it's not recommended to use a mouse with lower than 2000DPI with GIMX, you still can configure smoothing to make movements smoother.

GIMX has no impact on the aim assist, you can turn it off or on as you want.

Thank you Matlo for the tip!! I'll read the wiki... xD
Gimx is just awesome....
