Unity vs. Godot: One Developer’s Epic Showdown Reveals a Surprising Winner!

For years, Unity has been the go-to engine for countless indie game developers, powering some truly iconic titles like Hollow Knight, Among Us, and the original Subnautica. It’s been a staple, a true powerhouse in the indie scene. However, recently, there’s been a growing buzz around Godot, an open-source engine that’s quickly gaining traction as a viable alternative, often chosen for its ethical stance and financial benefits compared to Unity.

But beyond the ethics and business models, how do these two giants actually stack up when it comes to raw development power? One developer decided to put them to the ultimate test: by building the exact same game in both engines to see which one performs better.

Enter Thomas Grové, from Studio Interrupt. He was working on a survival horror game with his son and saw it as the perfect opportunity to conduct a real “apples-to-apples” comparison. Grové explained he’d always wanted to see a direct head-to-head, not just comparisons from different devs working on different projects. This was his chance to truly decide if he’d stick with Unity or make the switch to Godot.

The game he built, though in its early stages, included essential features like a complete character controller, a dynamic camera transition system, seamless scene transitions, a fancy tri-planar dither shader, and an interactive object system. He implemented all these elements in both Unity and Godot, then ran and tested them side-by-side.

The results? Quite eye-opening! From a pure functionality standpoint, Grové noted that both engines performed similarly, with minor ups and downs for each. However, where Godot truly shone was in efficiency. It blew Unity out of the water in areas like compiling, launching, and loading projects.

Let’s talk numbers: Godot was over five times faster at loading a project. When it came to exporting a project, Godot was a staggering 20 times faster. And for compiling a script – a task developers do hundreds of times daily – Godot was an incredible 31 times faster than Unity! Imagine how much development time that saves. Plus, Godot is a tiny program, taking up just 164 megabytes, while Unity weighs in at a hefty 20 gigabytes.

Grové concluded that “Godot beat Unity on every metric except for the final output FPS.” Even then, both exported projects ran at frame rates well above his target of 60FPS. His verdict? He’s likely sticking with Godot for his project.

While Godot’s victory seems like a slam dunk, some viewers pointed out that the simple nature of Grové’s test game might not fully reflect how the engines perform with much larger, more complex projects. A super high framerate on a basic scene doesn’t stress all systems equally. However, building two full-scale games just for engine testing isn’t really practical. The sheer consistency and the massive difference in efficiency Godot demonstrated strongly suggest it is, broadly speaking, the more efficient engine for many development tasks.
