X52 Pro twitchy on CoD elevator but not in calibrator

[klem]

I'm finding that when I make a fine elevator adjustment, usually to take shot, I get a small jump in nose position that only happens around the centre point. It is more than I get at other parts of the stick position.

I have done the Hall Sensor magnet mod and it is very smooth in Windows calibrator although it does move in tiny increments (2 pixels just like the other axes) rather than completely smooth but there is no disproportionate movement around the centre. In the game, Options... Controls... Axes the output sider follows precisely the input slider, 0.01 increment per 0.01 increment with no visible disproportionate movement around the centre.

I am wondering if there is anything else in the software that can be adjusted or perhaps its a software defect?

Anyone else got the same problem?
