"It's more than possible that your hardware configuration is the cause"

Its definitely not the hardware horsepower itself, as I have very good performance on 64 vista.

I'm also running with the very latest nvidia binary drivers, I have an intel dual core E2200 - not cutting edge but flash will actually take up an entire core with small animations, so it definitely seems like a bug to me.

"Get in touch with Adobe and let them know your config, the problem might be fixable."

I've spent a while (way way more than I ever wanted for something that they market as 'plug in' / 'just works') going through the ubuntu forums and launchpad, some stuff seems like fixeable problems that maybe I just couldn't fix, but heres a list of problems I have:

* Sometimes opening a new firefox/chromium tab/window and loading a website with flash will crash it, crashing all flash instances - so if I'm listening to a google tech talk or something I have to restart it and go hunt the on the timeline.

* Sometimes controllers just stop responding to clicks ( http://www.khattam.info/2009/08/18/solved-flashplugin-contro... )

* Flash will flicker as I scroll down firefox/chromium.

* This has stopped now, but at one point flash crashing wouldn't free its memory, and Xorg just started consuming more and more memory, bringing the entire computer to an almost halt!

* Some flash players/gamers/whatever when I'd press the fullscreen button would get from xorg as my resolution the sum of my 2 monitors - 2560x1024, which means they'd get clipped in half or they would get letterboxed (msnbc.com and youtube.com for instance) while others such as video.google.com works just fine.

These are just things off the top of my head - it seems flash is the #1 problem for 64 bit ubuntu from quick glances at the 64 bit forums, I've had a lot more problems, I tend to avoid flash websites as a result.
