thismeintiel said: I have a question. I understand how interlacing works, in that it takes two frames to make one image. But, what I want to know is, if it takes 2 frames to make the image, wouldn't they have to be rendering the game at twice the desired framerate to pull off the 60FPS of the final product? |
That is the trick.
Instead to run the game at 30fps... they are running at 60fps rendering half of the image in one frame and the other half in another... because we eyes are "slow" the senssation is 60fps with some blurry... you are receing 60 images per second but you need two of them to have the full picture... the trick happened because the images are so fast that we eyes see the two at the sametime... so we see one full 1080p picture but it takes two frames to be mounted.
It is a 1080i but interlacing the horizontal resolution and not the vertical.
