even if a Chrome update removed the Flash built into Chrome you could still download and install the PPAPI "Pepperpot" version of the Shockwave Flash player from Adobe,
if this SuperNova thing works ok at enabling Flash in Chrome and these guys are serious about keeping Flash games alive then it's prolly worth emailing them or using their feedback/bug report feature and pointing out Chrome has started forcing Flash to render in Software mode,
if they can code an extension to enable Flash I daresay they could also include a feature where you can chose to enable hardware acceleration in Flash,
it is an existing Flash feature, Chrome has done something to disable part of Flash's original functionality,
in TLS:DZ when you open the in game settings and click on the Flash tab you get an Adobe applet appear which has a tick box for 'enable hardware acceleration'
somehow Chrome sabotaged that with the release of ver.66
I asked for feedback because I can't be arsed to install the latest Chrome just to see if this extension works, my developer version of Chromium doesn't need an SWF Enabler,
if you think it does what it says on the tin I'll see if I can contact the dev's there.
one simple but effective extension could save the entire Flash gaming scene!
