WebGL performance issues

See original GitHub issue

Performance of WebGL compared with Chrome and Chromium is subpar

Whilst playing around with some WebGL 2 code I noticed that fps seemed to be roughly half of what Chrome was chucking out. Rendering 2 million cubes produced around 29fps whilst in Chrome it easily hit 60fps.

So I ran some more tests with a proper benchmark site https://web.basemark.com. These were all run on my Razer Blade 14 (2017) running Windows 10 x64.

Here are my results:

Brave Nightly 0.66.24 (Chromium: 74.0.3729.108) - Score: 585.08 (didn’t complete)
Brave Release 0.63.48 (Chromium: 74.0.3729.108) - Score: 531.3
Chrome 74.0.3729.108 - Score: 926.73
Chromium 74.0.3729.108 - Score: 947.62

These confirmed my suspicions and is quite substantial.

I did notice that Chrome has some additional Driver Bug Workarounds under chrome://gpu

disable_delayed_copy_nv12
disable_direct_composition_layers

And one additional one in Brave Release:

msaa_is_slow

If I had to guess I’d say this could be related to having a laptop with Intel and NVIDIA graphics cards. Those options that have been toggled above look like they’re related to picking the wrong card. But it’s just a guess.

Happy to provide more info or do more tests if needed.

Hi @bsclifton, unfortunately performance is the same. Still down at around 10fps (I’ve changed the test a bit so fps has dropped but it’s same on Stable) on my test whereas Chrome is getting about 45fps.

Tested on Version 0.69.24 Chromium: 75.0.3770.100 (Official Build) nightly (64-bit) that I just installed.
