Sounds like it's a right thread.
So, after upgrading to 10.13.4 yesterday. I noticed Chrome was
super sluggish, especially with 2D acceleration, like sliding down a part of the screen. images.google.com is a good example. Google for an image and then pick one. It will expand that image and the rest of the screen will be slid down. That part was
very slow.
I spent some time digging through this on the web, found a couple flags in Chrome that did nothing, then broke my Chrome completely, used Firefox to find a solution to recovered it...
Anyway, long story short - without Hardware acceleration it works
WAY faster. The CPU utilization noticeably kicks up, but I have 8700K that can handle it. I actually would upgrade to ATI, but this sucks
I have NVidia GTX 950 video (with 103 driver), Z370 Aorus Gaming WIFI (without working wifi/bt as it's not supported, lol) and i7 8700K as I mentioned it.
I do have 2 monitors, but I'm not using the built in video, at all. It's disabled in BIOS.
