Hello,
Can you describe with more precision how the mouse actually behaves? Examples: Is it stuck in an invisible box? Does it jump around randomly? Does it constantly drift in a direction?
It seems that GOG doesn't have a demo. Steam has a demo [1], can you check that the Steam demo is affected as well? Knowing that the demo is affected may give more incentive for a developper to work on the issue.
Regards.

I will test demo version of game from Steam later.
After additional tests I can describe reaction to mouse moving. First person view moving only when mouse moving - it's ok. But direction of view moving does not match current direction of mouse moving. It match to mouse moving direction which was some time ago. If v(t) - direction of view moving at time moment t (assuming that time passes only when the mouse moves), m(t) - direction of mouse moving, so this error can be described by formula:
v(t) = m(t/2)
But it must be:
v(t) = m(t)
