What makes C++ unbeatable for game engines?

Raw control over memory and cache, no GC pauses—essential for 60fps stability in physics and rendering.

Is C++ dying in modern game development?

Nope—powers 80% AAA titles; Rust's rising but <5% adoption due to compile times and ecosystem gaps.

Should I build my own game engine from scratch?

Only if you're AAA-scale or learning; indies thrive on Godot/Unreal unless you need hyper-custom perf tweaks.

Why C++ Clings to Game Engine Thrones Despite the Hype Around Rust

Q: Should I build my own game engine from scratch?

Only if you're AAA-scale or learning; indies thrive on Godot/Unreal unless you need hyper-custom perf tweaks.

Ever wonder why your favorite blockbusters run on code from the '90s? C++ isn't just surviving in game engines—it's thriving, and here's the market proof.

⚡ Key Takeaways

C++ dominates 90% of AAA game engines due to deterministic performance and low-level control. 𝕏
Garbage-collected languages like C# excel in scripting but fail engine cores with GC pauses. 𝕏
Building custom engines pays off for tailored needs, but stats show most fail—stick to Unreal unless revolutionary. 𝕏
