GOG has put alot of work in. I previously played this on Windows 7 years and years ago, and even there, the FMV custcenes did not work but hey they got them working here! I would suggest tweaking your controller mapping, contrary to what gog says, mapping your triggers works fine, also don't forget to open up their directx config tool, you can set it to render the game @ 4K with 8X MSAA, it's really nice.
