After installing 1809 Update on Windows 10 I experienced a laginess in all Chrome and Chromium alternative products.
(Canary, Brave)
Tried to use firefox instead with no issues. As mentioned in article here the only solution I found to fix this behavior was to change Permissions in the Windows Service “Cryptographic Services”

Services -> Cryptographic Services -> Properties -> 2nd Tab (Log On)
Change to Local System Account
Restart Service
