So all of a sudden the demo is now blurry. It was never like this before so I'm not sure if it's on Flash's end or something went wrong when you updated the demo recently.
I am on Chrome 21.0.1180.57 beta-m with Flash 126.96.36.199.
What's strange is when I go into the Flash settings and disable hardware acceleration, the demo goes back to it's crisp/clear normal self. It only seems to be when hardware acceleration is enabled that it goes blurry. Something to do with supporting older graphics cards perhaps? (constrained mode?)
I can confirm that even though it's blurry my benchmark results are amazing! Double the FPS at 60 with over 2000 objects compared to 340 objects at 30fps. So yeah, figured I'd mention that. (this is all with the hardware acceleration box ticked in settings before and after the demo/flash was updated)
