There are a few issues due to the limitations of WebGPU:

• Browser: A recent version of Chrome (or Chromium-based browser) with WebGPU enabled is required.
• Recommended platform: Windows 10/11 with a discrete GPU (NVIDIA / AMD) is strongly recommended for stable performance.
• Ubuntu: Currently not supported. Due to a Chrome WebGPU bug, fp16 is not properly supported on Ubuntu, which breaks our fp16 ONNX pipelines. We will enable official Ubuntu support after the upstream issue is fixed.
• macOS: GPU performance on most Macs is limited for heavy 3D Gaussian Splatting workloads. Unless you are using a high-end chip (e.g., M4 Max or better), we do not recommend macOS as the primary platform, as the viewer may run very slowly or stutter.
