This section of the doc seems a bit out of date?
- Chrome nowadays seems to be exposing disjoint_timer_query extensions on platforms with Site Isolation (see for example this). That is the case in my environment, where the Playground example seems to work,
EXTDisjointTimerQueryWebGL2instead of null,
EXT_disjoint_timer_query_webgl2is listed as a supported extension, etc.
- in Firefox on the other hand, enabling
gfx.webrender.debug.gpu-time-queriesdoesn’t work for me. I have also tried enabling
webgl.enable-privileged-extensions(suggested for example here), but that just crashes the tab with the PG in it.
If someone has suggestions for getting this to work in FF, I’ll take them!
- Firefox 91.2.0esr
- Chrome 95.0.4638.54
