Its an average FPS.
And as far as toning down the dread - how about none? There is none. Worrying about how to get your health up made that dread worse in the past, but now there is no problem. I was a little bored going through it on the hardest level possible. No challenge. The only thing that killed me was the end boss (but he is easy if you understand what power to get him with at any given time) and accidentally re-materializing in the middle of solid matter - probably because I was drinking a beer at the moment in time.
As far as the Nazi's getting you? It might have happened once or twice, but I really can't remember where. Besides the end boss getting me a few times, you could probably count how many times I died in the game on one hand. I think I died in the church once, and during some assault on the SS headquarters, but that's all that comes to memory. Maybe once in the Farm level, but I shot a video of it down below and went through it without saving so you can see how hard it is. Not very.
