Does resolution affect movement speed in Call of Cthulhu: Dark Corners of the Earth?

According to a review on GameFAQs the selected resolution affects character's movement speed. According to the PC Gaming Wiki the bug is fixed in the Steam version, but on the other hand the unofficial patch that fixes bugs and restores removed features only works with the retail version.

I spent a large amount of time constantly reloading that particular chase scene. After yet another death at the hands of that creature I found out something most curious and ill-conceived about the game. The resolution at which you play the game affects the speed of which Jack [the player character] runs.
