Why 4K Gaming Isn’t the Graphical Upgrade You Might Expect
If you’ve played games on a 4K TV and thought, “this doesn’t look that much better,” you’re not alone. On paper, 4K offers a massive leap in detail compared to 1080p, but does that paper specification translate to real-world differences?
The Performance Gap Between 1080p and 4K Is Massive
To put this all in context, it’s important to understand just what it takes to render a game at 4K. Many people may not realize it, but a 4K UHD screen has four times the pixels of a 1080p display. If you’re rendering graphics in real time, that’s a massive increase in the workload your GPU has to complete with each frame.
Assuming a linear increase in the computational power needed, each frame should take four times as long to render. In practice, the render time is a bit better than that, thanks to various tricks that help some aspects of graphics rendering scale more efficiently. But no matter which way you slice it, 4K exerts a massive toll on frame rate.
If you want to keep that (native) 4K resolution but increase your frame rate,…
