Care to post what relevance this has to GTS?
I am educating you.
It's funny that you post that, because after reading through it, it's obviously not going along with what you're claiming
So this part is essentially meaning that because you can interact with it, likely meaning actually playing the game. That's real-time, which that trailer is not.
So essentially, this is the cinematic aspect of games, where they are able to do much more than actual gameplay. This is what the GTS trailer with that tunnel shot.
Hey look, they even give us an example so we can sift through it and see if we catch it. Up to the 33 second mark is obviously offline, pre-rendered cinematic. You can tell because once the transition goes to real-time you can see the obvious downgrade happen.
Essentially, the trailer was not real-time, it was pre-rendered. Theres things happening within it that just aren't possible in actual game play so far. One thing to point out is headlight illumination.
Real-time rendering: "in real-time rendering, the computer is producing all the images from 3D geometry, textures, etc. on the fly and displaying it to the user as fast as possible (hopefully above 30 frames a second)", and Offline rendering: "Offline rendering refers to anything where the frames are rendered to an image format, and the images are displayed later either as a still, or a sequence of images (e.g. 24 frames make up 1 second of pre-rendered video)".
If you cannot control anything in a 3D scene, it does not mean that you are seeing the output of an offline renderer. When we drive the car, we are seeing real-time graphics. When we are watching replays, we are seeing real-time graphics. The 3D graphics that you see in the trailer are real-time graphics. Those are captures of real-time graphics.
