Sometimes, your graphics card's details are exposed to the web. Yours are not right now, though, which is good. Try opening this page in different browsers – I found Chrome had much more information than Firefox, for example.
The Code
//Function to grab GPU data.
const getGPU = () => {
const ctx = document.createElement('canvas').getContext('webgl')
const ext = ctx.getExtension('WEBGL_debug_renderer_info')
return {
card: ctx.getParameter(ext.UNMASKED_RENDERER_WEBGL),
vendor: ctx.getParameter(ext.UNMASKED_VENDOR_WEBGL),
}
}
//Put the GPU data into the web page.
const gpu = getGPU()
document.getElementById('graphics-card-test-output')
.textContent = `Yours is ${gpu.vendor}'s ${gpu.card}.`
