I’m in the thick of developing my own 2D game engine, and I need to make a decision on which rendering backend to go with. Honestly, I’m feeling a bit lost trying to weigh out my options, and I’m hoping you all can help me out.
First off, let me lay out what I’m aiming for. Performance is, without a doubt, my top priority; I’m talking about FPS and memory efficiency because the game is likely to have huge open worlds and run some pretty heavy simulations. I also want it to work cross-platform, particularly for desktop and mobile, but web support isn’t a big concern for me. Most importantly, I’d prefer not to dig too deep into low-level graphics APIs if I can avoid it.
Now, I’m looking at four potential options:
1. **WebGPU** – This is all about modern graphics on the web, and I hear it’s pretty powerful. I could see how it might handle a lot of draw calls quite well since I’m going to have a massive amount of dynamic objects and possibly even an Entity-Component-System (ECS) architecture down the line.
2. **Raylib (C or C++)** – This one’s intriguing because it’s native OpenGL based and comes with a simple API. I appreciate the ease of use, but I wonder how well it scales for performance with larger worlds and high demands.
3. **WebGL (2.0)** – While it’s an option for web deployment, I’ve heard the performance isn’t as great as WebGPU and could limit me given my engine’s heavy requirements.
4. **Canvas 2D API** – I know this one’s the weakest in terms of performance, but for 2D games, I’m wondering if it might still be sufficient. Still, I’m a bit worried about its limitations with heavy draw calls.
I keep going back and forth between JavaScript with WebGPU, Raylib with C/C++, or even considering wgpu with Rust. From what I’ve described, does anyone have experience with these renderers for scenarios like mine? Which one would you think would give me the best performance for intensive 2D rendering? Would love to hear your thoughts!
It sounds like you’re embarking on an exciting journey with your game engine! Based on what you’ve shared, here are some thoughts on the rendering options you’re considering:
WebGPU
This is definitely a strong candidate if you’re looking for high performance and future-proofing. WebGPU provides modern graphics capabilities, which can handle multiple draw calls efficiently—perfect for your dynamic objects and potential ECS setup. If you’re leaning towards JavaScript and want to leverage the web, this could be a great choice.
Raylib (C or C++)
Raylib is known for its simplicity, which is awesome for beginners. Its use of OpenGL provides decent performance and should scale well for 2D games. However, if you’re diving deep into massive worlds and heavy simulations, you may find yourself bumping against some performance limits. It’s user-friendly but might require some optimization down the road.
WebGL (2.0)
While it’s an established option for web deployment, you’re right that it may not give you the performance headroom you’re looking for. If you’re primarily focusing on desktop and mobile, WebGL could come up short, especially with your emphasis on handling a large number of objects smoothly.
Canvas 2D API
Canvas is super straightforward but definitely on the slower side, particularly for a high density of draw calls. If your 2D game is simple and doesn’t require extensive performance, it might be sufficient. But for your vision of large open worlds, it could become a bottleneck quickly.
Considering your requirements for high FPS and memory efficiency alongside cross-platform support, WebGPU seems like the best fit overall if you’re comfortable with JS. For a solid C/C++ experience, you might find Raylib helpful—just prepare to optimize. Raylib can balance performance and ease of use, but keep an eye on potential limitations with larger scenarios. If you’re thinking about rust, wgpu might bring you the best of both worlds, being performant and that it allows you to maintain a high level of control without getting too deep into graphics APIs.
Good luck with your engine! It’s a lot to weigh, but you’ve got some solid options in front of you!
Given your emphasis on performance, massive worlds, and heavy simulation workloads, Raylib in C/C++ or wgpu with Rust would likely be your best choices. While Raylib offers simplicity with a clean and straightforward API built on OpenGL, performance for scaling large dynamic scenes is dependent but still fairly robust; however, wgpu (Rust bindings for WebGPU-like API) stands out more clearly when handling massive geometry, batching draw calls efficiently, and maximizing system resources while abstracting enough low-level complexity to remain comfortable. Native wgpu’s modern GPU tech stack is explicitly designed for optimized and performant high-throughput rendering scenarios, which pairs incredibly well with demanding 2D game engines, particularly ones employing ECS architectures and complex simulations.
WebGPU via JavaScript is powerful but brings runtime overhead and is limited by JavaScript’s single-thread constraints, potentially capping performance significantly. WebGL 2.0 and Canvas 2D API would bottleneck in large worlds with heavy draw calls and numerous dynamic entities, quickly becoming hurdles—especially if performance at scale matters to you. If your priority lies in high performance combined with reduced friction accessing GPU resources and multi-platform support (excluding web), leaning towards native implementations like Raylib or, most ideally, wgpu with Rust is strongly advisable.
