Even though I have vsync enabled, I am still experiencing screen tearing when moving the character around. Also, whenever I select 4k resolution, it reverts back to 1080p in the menu. Anyone else having these issues?

GOG support contacted me about these issues and guess what their brilliant advice was (after the typical run as an admin, check permissions, and check the firewall settings)? How about for me to stop using my HDTV and purchase a monitor to play this one freakin' game?

Needless to say, I now have a new policy for purchasing new games. From now on, I will purchase them first on Steam to make sure they are running ok. Then I will get a refund from Steam and purchase them on gog (maybe, if the game is good enough). Gog's support team and their refund policy are awful.
