This situation occurs on three computers I can think of, one running
NVIDIA, one ATI and one an Intel graphics card. All running the binary
drivers from the restricted drivers manager.
I don't think this is a graphics problem to be honest...
If anyone is interested in testing this. Take a dual-boot laptop/pc.
Visit the cartoonito.co.uk website and try a few games using Firefox
and the Flash plugin under Windows XP, then under Ubuntu.
See what the responsiveness/smoothness of web browser operations, for example:
* Type a url into the address bar in Firefox 3. The browser begins to
scroll up previously accessed sites as suggestions. Note the
performance under both OS's.
* Try some of the Flash games mentioned under both OS's. Note the
performance of animations etc.
I'm sure it's not me going mad!
