The Graphics and objects don't scale to 1080p. The camera is still very close to the charcater, the HUD is gigantic, and the framerate is locked to 20fps, just like the OG. I own a physical version, and I have been playing with a mod that scaled objects and the HUD to a size that a 1080p display would have them. This comes at a price, since the mod unfortunatelly removes quests. I was expecting something similar from GOG, but it was my fault. I should learn to manage my expectations the next time.
The game would be great, not doubt about it, but the issues it has just ruins it for me. - Enemies shoot you through tents, as if they have x-ray vision. - The textures of the map are not rendered correctly, and grass grows 2 meters away from the player, even after setting the game to ultra.
