But I think it's pretty much safe to say that under most conditions Adobe Flash will run better on your PC hardware since all the GPU (Graphic cards) manufactures make sure to optimize their VGA cards to run Flash under hardware level.
Anyhow, Adobe recently released the latest version of the Flash player which makes it now the version 10.3.181.22 and below are few of the new improvements/features.
*. Media measurement - By using the Adobe's API, now web developers can monitor their videos and their distributions (where and who watched them, etc) with ease... "with as little as two lines of code" according to Adobe's own words.
*. Clear the Flash Player Cache with ease - Yep, I always clear by browser cache. But clearing FP cache ain't that easy. But with this version now Flash player will let you clear its cache using almost all the major web browsers such as Firefox4, Google Chrome 11 and Internet Explorer 8.
*. Easily access its settings - Now users with MS Windows/Mac or GNU/Linux users can access FP settings in their "Control" panel section, of their operating systems.
Although these are the major new features according to Adobe but the 10.3 do come with bug fixes, enhanced video playback and security features as well.
If you use Ubuntu 11.04 Natty Narwhal then you can install the latest version of the Flash Player (10.3 in this case) by clicking here and follow the instructions on your screen. That's it.
After doing this, whenever Adobe releases a new version/update, all you have to do is enter the below command in your Terminal.
sudo apt-get update
sudo apt-get install adobe-flashplugin
