i have virtual server machine with windows 8.1 and when i open threejs site with 3d model there its getting just stuck when i scrolling down, cus model start rotation on scroll.
fps drops to 3-4 even at threejs examples. On normal windows 10 with live server all totaly fine
Yeah I think that is a software emulated version of Vulkan.
Somehow the browser has had hardware acceleration disabled, or the machine itself doesn’t have a proper GPU.
Google says:
To enable hardware acceleration in Chrome on Windows 8, open the Chrome browser, click the three dots in the top right corner, select “Settings”, then navigate to “System” on the left side panel and toggle the option “Use hardware acceleration when available” to “on” - remember to restart Chrome for changes to take effect.

so what you reccomend is it windows server 8.1 low or i need maybe windows server new version ?
If other threejs examples are running slowly, then its an indication that your drivers are bad somehow, and chrome is defaulting to software emulated WebGL.
Can you try it in Edge browser and see if the behavior is the same?
