I am having similar issues. Did every trick in the book. This started a week or two ago, perhaps with an update. I'm very experienced technically and this one has me baffled.
One thing I noticed where Chrome really barfed on was in-address bar searches. Chrome just sits there doing nothing for several minutes.
In the end, I've just moved to Firefox. PIty, I do love Chrome.
I will keep trying though, but not in the middle of prime production time.
Update: Did a FULL uninstall, and then tried the "Disable Hardware" fix mentioned (which I had tried before to no luck). This time, I'm noticing a big improvement in speed. So... fingers crossed.
