用 Opus 5.5 打造的 UE5 类魂 Demo 在 WebGPU 中运行

Hi r/ClaudeCode, this is a Dark Souls style UE5 demo I assembled using Claude. It's a third person knight with sword / shield, a gothic cathedral courtyard, a health and stamina HUD, and a skeleton to fight. Full disclosure art and combat systems and environment are all a Fab pack I purchased, I didn't make those.

What I wanted to test was whether Claude Code (Opus 5.5) could my game project and get it rendering client-side in a browser tab with WebGPU and WebAssembly. It renders on your own GPU, with no install and no cloud streaming.

Using our internal build tooling, Claude:

• ran the UE5 builds and fixed/triaged bugs
• ported the project to a WebGPU rendering path using our Strata tool (lmk if you want more info on this)
• added additional game mechanics and levels beyond what I had previously manually added
• profiled and optimized until it ran smoothly in the browser

I set up the tooling and reviewed the output. Claude did the porting work.

Disclosure: it's hosted on my company's platform.

I'd like to hear how it runs on your hardware, and what breaks.

Please try it out and lmk what you think: https://simplystream.dev/HyZObyKI
