Having completed the game now, I can say that it's 100 % a shitty lame-ass console-to-pc port. It's got one of the shittiest optimizations I've ever seen, and it stands in stark contrast to Alien Isolation which got released a few weeks earlier, that excelled in optimizations for the PC.
The FoV is totally screwed for "dat cinematic experience" and the black borders give me cancer. It was obviously to damage control the graphics of the game, because even on the PS4 and XBOX1 it has trouble maintaining 30 fps..
That said though, I really enjoyed the game. It HAS pretty good graphics and visuals, and the story is somewhat interesting, the challenges are .. well challenging and the boss fights and enemies are cool. The different areas are all varied and makes the game come alive. It feels very much like a Resident Evil 4 on crack-cocaine, and a much more twisted and sinister version of that game. Yes, it's very combat heavy, unfortunately, but so was Resident Evil 4, and that game was ace.
All in all, it's a known formula, but it kinda works out. I enjoyed my time playing through, and clocked in about 18-20 hours too..
A 6.5 / 10, because of the very poor optimization work. Would've been a 8/10+ if it was optimized like Alien Isolation was. Honestly, you would expect better from a publisher like Bethesda and a developer like Tango, to optimize the game. They are triple A companies.. for shame.
Is it worth buying? In it's current state, no. Maybe at a reduced price.
