@bribes could you please include some benchmarks and a code example to reproduce?

My guess it's related to the hardware you're using but I can try on my systems.

You can just test turning on and off hardware acceleration on your browser here. https://bs-community.github.io/skinview3d/ and check your task manager.

Any updates?

@bribes, you will probably get more traction on this issue when you include at least some of the following.

• benchmarks
• browsers tested
• hardware specs

Bruh ok but this is a issue for like all browsers and hardware and like everything if you turn off hardware acceleration but sure

these issues are still present

I am suffering from the same issue. The preview is always rendering even when it is stationary, which always results in 100% CPU usage. I think it should be like the "NameMC" skin viewer, which does not render while stationary, but only when animations or camera operations are performed.

Indeed does look like an issue when hardware acceleration is turned off in Chrome.

Tested Edge as well and got the same issue as Chrome.

Tested in Firefox and don't see the same issue though 🤔.

Since both Chrome/Edge had this issue it's perhaps something related to Chromium and not specifically skinview3d. To rule out Skinview3d I visited a few of these threejs demos and the CPU would spike in Chrome/Edge.

I had a brief look for an upstream issue on threejs and chromium but found nothing related.

A good idea would to display a static model if hardware acceleration is turned off using something like https://github.com/pmndrs/detect-gpu until this issue is resolved. if that's even possible to resolve this.

When hardware acceleration is off, on lower end hardware, the model absolutely destroys performance.

@tcrch that is a fair solution.

If anyone has bandwidth to throw something together to detect if you have hardware acceleration enabled and raise a PR that would be appreciated.

Found this thread which talks about implementing on-demand rendering.
