My machine is a Core i7-8700 with an NVidia GTX 1050 Ti. I’ve got a scene that runs pretty well in Chrome and Edge (Chromium 93), but the performance tanks in Firefox 91. According to the scene inspector, we’re using babylon.js 4.2.
Looking at the scene inspector, I can see that between the two browser engines, the graphics driver is different, and in turn, there is one feature that isn’t being used in Firefox. In Chromium, the listed driver is in line with what I have, ANGLE (NVIDIA, NVIDIA GeForce GTX 1050 Ti Direct3D11 vs_5_0 ps_5_0, D3D11-22.214.171.1247). But in Firefox, the listed driver is ANGLE (NVIDIA GeForce GTX 980 Direct3D11 vs_5_0 ps_5_0) and parallel shader compilation is disabled.
I’m not certain if this is the root or just a symptom of my performance issues, but what might cause this?
Note that I’m in an enterprise environment and the advanced configuration pages in my browsers are locked out; trying to access about:config in Firefox gives me a message saying that the administrator has blocked access to the page.
