Wow, hehe. I just completed the demo. Its amazing, and pretty freaky, but didn't scare me when for example that girl kept appearing.
With my system (see specs below)
I could run at reletivley good settings, and I think I was getting about 35-60fps though theres no frame counter to suggest anything. Any one know how you can get that on this game, like with Half Life 2?
As for the graphics though, just amazing!
Even when I was running on Medium/High settings (Soft Shadows off and Shadows on Medium, All model/environment details on High, textures on Medium, effects on High, AA off, running at 800x600) its just amazing to see!
It just never jerked (which is what I hate the most). Loading times were great too with a level taking approx 5-10 seconds a time to load a saved game, which is comparable to Half Life 2 which takes about 15-30 seconds.
Plus, that slow motion effect is great. I loved it when it just came on, and you had no choice in it, for example when those enimies smash through the wall.
I was dissapointed when it ended
Though, hehe, before it faded out, I had no weapons anyway, and only my fists, so in a way, I was lucky...
I'm happy with how my computer worked though, considering how new the game is.
if anyone can give me a way of getting a frame counter, I'll show you exactly what I got.
I at first tried running at super high settings except for the textures, which stayed at Medium, and it did very well in places, except for when you were out in the open and a few enimies were in place, which is when the frame rate probably went to the 10fps mark.
Using my 9800PRO with 128mb of memory, I found the Soft Shadows option (Looked great) proved the most fps hitting. Next was the Antialising, which also cut away the fps, though surprisingly, not as much.
