Do you know what changed in Chrome that caused the slow down?
- masswerk 7y agoI had a number of theories (involving arrays newly allocated, where they should have been reused in a managed stack, and extensive heap allocation, clamped array implementation, side channel attack mitigations running wild, etc). However, as it turns out, it's apparently about hardware acceleration (and probably about some overoptimistic assumptions made). I.e., I just tried on an old MacPro (late 2008) with hardware acceleration disabled (Settings -> Advanced -> System -> Hardware acceleration + restart) and it runs smoothly. Edit: Just updated the page accordingly. Thanks to everyone who helped in focusing on the matter of hardware acceleration!
- masswerk 7y agoNow we only need some code to opt out of Chrome hardware acceleration on a per-page basis.
