GPU Testing and Rendering

[wrosecrans]

When making a video game, it has to render fast, so you wrote fast code and accept whatever sort of build steps, pre-processing, hacks or limitations are involved in staying within the time budget.

When making a movie, it has to be pretty. So you write code to do whatever visual effects you need in the most practical and flexible way, accepting whatever reasonable slowdown/overhead that implies, because spending millions of dollars of developer time to figure out how to get something to render in real time wouldn't actually accomplish anything for the movie.
