I think this is useless fluff. It’s essentially just a few compiler flags being changed. I’m pretty sure the Chromium engineers are very well aware of those and made the decision to use the one they did. I don’t know which ones, but opting for higher optimization has to have detrimental side effects. Also, the lighthouse score changing?? Isn’t the entire point of Lighthouse to grade the website and not the machine the test is being run on???

GTA Online load times were brought from 8 minutes to 35 seconds by a fan patch[0], don't assume everyone knows what they are doing or cares about the outcome.

  Why not ask someone working directly on this? Like Bruce Dawson https://randomascii.wordpress.com/about/ https://randomascii.wordpress.com/about/

In my experience such improvements often stuck in backlog until removed. Someone added them because they are “nice to do”. But later person changed team or was buried under other work.

  This exactly. Someone may be aware that it's possible to change the flags for improved performance, but they likely have a mountain of other things they need to deliver and the current set up seems to work fine so no attention is given to changing. Anyone else coming across these flags will probably just have their eyes glaze over and wonder how any of it works at all.

    I must thank RobRich999 for the loop optimizations.

Hey, dev here. The compiler flags have been noted to cause binary bloat, which is why they arent used. The AVX flags are noted in the source to be the next step, after they switched from SSE2 to SSE3. Lighthouse measures many things, some not on the client side at all. However, it does measure rendering speed, which is affected by browser speed/hardware. Thats why i included it
