Testing Unity's WebGL capabilities for different versions and platforms

✔️ : Supported | ⚠️ : Supported, but runs poorly | ❌ : not supported | ➖ : Not applicable

• Physics
• GPU Instancing for materials
• Shadows
• Brotli Compression

• The server is configured to support wasm streaming and brotli compression, see .htaccess 2020 .htaccess 2019
• In order to get rid of the warning on android/iOS it is removed in a post process build step (File)
• You might need to reload the page on android/iOS when running the first time
• This is a very small example. When building larger WebGL applications, you might run into problems with memory or compile errors. I recommend to build from the start and very often, to catch the changes that create those problems.
• If you want to have the smallest file size possible, take a look at Project Tiny or web-specific libraries like Three.js.
• URP adds additional 2.5 MB file size compared to the builtin render pipeline.
• Removing the default skybox will save ~30kb.
• In general the performance for URP seems to be better compared to builtin, but it has a larger build size.
• Internet Explorer does not work for Unity WebGL builds, since it does not support wasm.
