Why does a computer need a dedicated graphics card for high-graphics video games, but can play 4K quality video without one?
In: Technology
There’s more math involved with games than videos. Many games have their own physics. So if you’re playing a game and your character fails off a cliff while shooting rockets, the game has to calculate rate of fall, graphics for the scenery and how they’d change, and ditto for the rockets. All of that takes processing power, which is part of why some games heat up your unit more than others.
A video is just playing a series of pixels/ colors/ images in time with an audio file. The system doesn’t have to process/ think as much.
