I'll probably stop playing then as I generally play this to kill time. Not worth dropping my main browser just for one game.
Or I'll just deal with the bad frames. Ah well, thanks for the help everyone!
what makes you think you have to drop Chrome?
you can just use a secondary browser to play dz,
I've got Firefox as my main browser, set as default, and then Chrome, Yandex, IE11 & Pale Moon as alternatives, I had Opera, Vivaldi & FB Gameroom installed at one point too!
Google Chrome is just Google's build of the chromium project with some Google branding and bit's and bobs added, the same with Opera, Vivaldi & Yandex,
of all the chromium family only Yandex hasn't nerfed Flash Player so that it renders in software mode,
I think the switch to software rendering is to pander to mobile devices which now make the majority of internet connections,
just download and install Yandex as a secondary browser, migrate your settings from Chrome and use it for tls:dz when you want to play,
carry on using Chrome for everything else you do online, (while they still allow you to)
try making a tin foil hat to block Google's mind control app and have a think about it? (make sure you put the shiny side of the foil on the outside)
