The game really is unplayable with about 15-20 FPS all the time. Just bought the game and can't even play normally. I read on the internet that more people were having these framerate problems since the last update of Friday. I tried everything I could find and think of to fix the issue, but nothing worked out. My video drivers are up-to-date and normally I can run any kind of game on my PC, because it's built to play real heavy modern games on with high settings. I can run every other game (also using Unreal Engine) without any lag/FPS problems etc. This is the first time something like this is happening to me. Even in the menu I have the same FPS as in-game (about 15-20 FPS). Something is really wrong with this game, and I hope a game update or fix will come soon, or else I will demand my money back from Steam, because this is just unplayable..
