I had begun to think that I was imagining things with Chrome but it definitely seemed to be slowing down. When I upgraded to Windows 10 it seemed to become even slower. On searching the web, I found this possible solution – it seems to have made life better on my PC so I would love to hear if it works for you.
- Open Chrome and click on the menu button (top right of screen)
- Click on settings and then scroll down to Show Advanced Settings and click on it.
- Scroll down to the System section and then turn off the Use hardware acceleration where available (so there is no tick).
- Close Chrome and restart it.
It made a difference for me, do let me know if makes a difference for you.
Another fix suggested is to check that the extension to phone via skype is either disabled or deleted – unless you wish to use this feature of course.
