> The objection (more surprise than objection) is that web browsers are supposed to be sandboxed environments. They are not supposed to be able to do things that negatively impact system performance.

I agree with the sandboxing model, but it is orthogonal to WebGPU and impacting system performance. Sandboxing is about making the environment hermetic (for security purposes and such), not about full hardware bandwidth isolation.

First, there is no way for web browsers to have no system performance impact whatsoever. Browsers already use hardware acceleration (which you can disable, thus alleviating your WebGPU concerns as well), your RAM, and your CPU.

Second, afaik WebGPU has limits on how much of your GPU resources it is allowed to use (for the exact purpose of limiting system performance impact).
