I have been updating a couple of pages with latest viewer and tested the HTML5 performance in 3 browsers.
Both on my iMac and windows XP on Parallels
Safari,everything works. In Windows I had to update from 5.0 to the latest version to get the fullscreen to work (also from iFrame)
Firefox Works fine on Mac but on Windows it does not work even after updating to latest 15.0.1 Cubefaces upside down and with some missing.
I checked my settings and I use video VRAM 512mb and enable 3D acceleration is checked.
Chrome works on both platforms but they both show same errors at cubefaces like below.
First I thought that this was because of the iFrame but loading the page directly gives same problem. Cubefaces I used are from 1600-2000.
This one is 2000pixels
Here is the link without iFrame http://www.panoramas.dk/7-wonders/seven-wonders/corcovado/
Apparently it is still to early to set automatic choice for Flash/HTML5
