Many people assume that modern graphics technology is now capable of rendering photorealistic video games. If you define photorealistic as any still frame is indistinguishable from a real photo, then we can get pretty close. Unfortunately, the problem with video games is that they are not still frames - they move. What people don’t realize is that modern games rely on faking a lot of stuff, and that means they only look photorealistic in a very tight set of circumstances.
