Visual Computing Still Decades from Computational Apex

With a resolution of about 30 megapixels, the human eye is able to gather information at about 72 frames per second which explains why many gamers debate the need for frame rates higher than 70 in games at all. One area that Sweeney did not touch on that I feel is worth mentioning is the brain’s ability to recognize patterns; or more precisely, changes in them. When you hear the term “stuttering” or “microstutter” on forums this is what gamers are perceiving. While a game could run at 80 FPS consistently, if the frame rate varies suddenly from 90 FPS to 80 FPS then a gamer may “feel” that difference though it doesn’t show up in traditional frame rate measurements.

In terms of the raw resolution though, Sweeney then posits that the maximum required resolution for the human eye to reach its apex in visual fidelity is 2560×1600 with a 30 degree field of view or 8000×4000 with a 90 degree FOV. That 2560×1600 resolution is what we see today on modern 30-in LCD panels but the 8000×4000 resolutions is about 16x that of current HDTVs.
