The Terror of Alan Wake 2
The first game to bring my gaming PC to its knees. Crysis Remastered on Can It Run Crysis Settings with Raytracing? No problem. This? LEGO box people and out-of-sync cutscenes. On the plus side, this is how it looks on the lowest settings possible; it's a beautiful game.
It is too bad I can't play it due to the cutscenes crashing my PC; this game is a blast.
I looked it up, and this game uses an in-house engine, which explains a lot.
