So, i have a laptop, with integrated cpu graphics (Intel UHD) and discrete gpu (RTX 3060), first times when i set in Windows settings to use Firefox powerful gpu, it just won't, i tried restarting browser but i forgot that i have opened private tab, so i not restarted browser. So, on any pages like WebGL Aquarium, i have pretty low fps, in comparison to other browsers (like Microsoft Edge or Google Chrome). Then, after i see that tab, i closed it, and after restart i got my fps, but.. still lower than other browsers, on WebGL Aquarium with 30k fishes, Firefox max fps is around 35, but on Chrome is around 70 (two times faster). I found one page that shows gpu that uses for acceleration, and it shows pretty weird information in Firefox. https://kdashg.github.io/misc/webgl/low-power.html So, in Chrome it says like "Nvidia RTX 3060 Mobile GPU", and when i choose integrated gpu for this browser in windows, it says like "Intel UHD GPU", but, in Firefox, on first tries it said same, but when i got discrete gpu acceleration, it says that i have "Nvidia Geforce GTX 980". I was like, what? Where it did come from? This explains why I have a fps two times lower but who will explain to me why this gpu is here? I tried to change all acceleration settings in browser, but when i just disabled any acceleration, still shows GTX 980 what is more weird than if it just shows like nothing or Intel GPU, cause is disabled but still uses hardware acceleration, but no matters if i let Firefox use recommended performance settings or set to use acceleration when is available, it shows GTX 980. I think it's about a bug, or something? I can't say that's Windows problems, drivers, or any other thing, cause, other browsers don't act like this, and i just don't have GTX 980 in my laptop on side with RTX 3060 and Intel GPU, anyone even know that laptop like this exists? Screenshot don't wanna upload here so i decided to place it on imgur. https://imgur.com/pyMZQr0
