--- Comment #5 from Roberto benfi@hotmail.it 2010-11-23 08:25:26 CST --- This issue might affect all source games, since is an update engine-related. I'll paste the engine changes:
[Windows] Added support for raw mouse input. Raw input reads directly from the mouse, bypassing Windows control panel mouse settings. This addresses issues with high DPI mice, and provides for a more reliable controller experience at various resolutions [Windows] Improved custom mouse acceleration [Windows] Updated mouse configuration UI to support raw input and acceleration; added tooltips to some of the options [Windows] Fixed UI tooltips so that they display correctly on first hover
As you can read, source engine does not use windows cp settings. So...wine doesn't handle raw input properly?
