I always play one card game online, and now it looks like I play it on 20 years old PC. I also tried it on Opera gx, and it works smoothly. I guess that's not only a thing of one online game but many websites, which are not workable any more.
Game I play is https://steemmonsters.com

I had to go to amd catalyst control center and edit some settings to work somewhat better

I have a problem with Opera's google search above speeddial. Sometimes it works, sometimes I get blank site (This webpage is not available / Unable to look up www.google.com.)

I am still using O12 as I NEED this function multiple times DAILY. And I know I am not the only one here as this is very useful function
