Vivaldi does a decent job when it comes to internet browsing, a lot of users prefer it over Google Chrome and others. The browser is based on Chromium like Opera, Chrome and the new Microsoft Edge. Now, the team associated with the development of the browser recently found Windows 7 better than the Windows 10.
The Vivaldi team noticed that browser test runs faster on Windows 7, faster than Windows 10. Vivaldi then reached out to Chromium team for help in finding what might be the root cause of the issue. It was found that the Control Flow Guard(CFG) in Windows 10 caused the issue.
For those unaware, Control Flow Guard is a very crucial security feature first introduced in Windows 8.1. It is turned on by default and helps in preventing certain kind of exploits from affecting your PC performance. Long story short, you should never think of turning it off.
Aside from the Chromium team, Vivaldi reached out to Google for help. The search giant also came up with a similar statement: Control Flow Guard is the culprit. The test runs as good as Windows 7 when CFG is turned off.
Thank you Bruce for noticing and analyzing this perf issue. We investigated the root cause and built a fix. It will flight in a couple weeks…

Microsoft, however, has built a fix to counter the issue after the company was tipped off. The company confirmed that the fix will be rolled out to users in a couple of weeks.
