Congrats on the most insane take in this thread. The game looks an entire 2 generations ahead of the original because shockingly, it's 2 generations of rendering tech between them. This is even worse than the insane cope of people that think TLOU remake looks like the OG, because at least that was a very late PS3 game pushing the system to its actual limits Dead Space was still an early gen PS3/360 game and looks like it, no matter what res you're running it at on PC.
This is closer to a Demon's Souls OG to remake situation and is a massive improvement to not only overall graphics but the actual atmosphere of the game due to the leaps lighting, particle and fog rendering have went through over the years.
