Doom's Engine Has an Amazing Way of Rendering

A single frame of a new Pixar movie takes roughly 30 hours to render. That's the only way they can get shocking clarity and detail of every strand of hair. Doom, on the other hand, has literally no way of doing that. It needs nearly instant rendering to be viable as a video game. So how is it that Doom has such amazing visuals, even at 4K?


Boom. Headshot.

"Imagine a sandwich." That's what Marty Stratton in the middle of the panel. The panel was filled with the minds who made the engine behind Doom, Id Tech 6. "The bottom bun is the operating system, and the middle is all the drivers piled up really high." I worked hard to imagine this data burger. They explained that as games got more complicated, the drivers (the center part of the sandwich) kept growing to massive proportions. This caused an issue with going further with the technology. The more to an engine, the more power it needs to run properly. Id Tech 6, though, eliminates the need for so many drivers. Instead, it focuses on developing a strong relationship with the GPU. It directly tells the GPU what it needs done, which opens up the future of game development. Whether Id Tech 6 will lead the charge in the future of gaming is up for debate. One thing is for sure, I'm definitely impressed.
