Don&#x27;t get me wrong: this is cool. It just makes me sad the performance is so night vs day on Firefox vs Chrome (Nightly and Dev branch on Linux). The former is glitchy (some planes are rendered when they should be hidden behind other geometry?) and stutters.<p>It&#x27;s even sadder that even in Chrome the FPS is noticeably low. This isn&#x27;t a gaming rig, it&#x27;s just an Intel card, but it can run plenty of games (at 40+ FPS) from the past five years that are drawing far more than this demo, and reacting to far more inputs.<p>In principle I love the idea that we could write everything to be portable across OSs and form factors by writing for &#x27;the browser&#x27;, but still at this point, on this modern computer, the performance is noticeably worse, and ultimately lackluster.<p>It&#x27;s the same story on mobile, and not just limited to GPU-bound applications, despite the prevalence of web tech in that space. At the end of the day all of this &#x27;write it for the browser&#x27; just translates to using far more CPU cycles than putting in the effort for &#x27;native&#x27;.
