Hi.

I wonder if this is related to the way that the StreetViewPanorama
undocumented 'mode' property value 'webgl' is broken with v3.4 of the
API...

The StreetViewPanorama undocumented property 'mode' could be set to
'html4', 'html5' or 'webgl'.
More info on mode can be found here:

https://groups.google.com/group/google-maps-js-api-v3/search?hl=en&q=street+view+undocumented+mode&hl=en&;

I've taken the official Street View example and modified it so that
the API version and mode property can be set:

http://code.martinpearman.co.uk/street_view_mode/streetview-map.php

That's the unmodified example, try it with mode set to webgl:

http://code.martinpearman.co.uk/street_view_mode/streetview-map.php?mode=webgl

I see no Street View imagery with any browser.
(Firefox, IE8, Chrome, Safari and Opera on Win7).

v3.3 of the API and webgl work though:

http://code.martinpearman.co.uk/street_view_mode/streetview-map.php?mode=webgl&v=3.3
(Try this link with Chrome to see the better performance that the
webgl value gives)

'webgl' isn't enabled by default with Chrome and v3.3 it seems:
http://code.martinpearman.co.uk/street_view_mode/streetview-map.php?v=3.3


'html4' and 'html5' both work with v3.4:

http://code.martinpearman.co.uk/street_view_mode/streetview-map.php?mode=html4

http://code.martinpearman.co.uk/street_view_mode/streetview-map.php?mode=html5

One thing to note is what video hardware is installed on your computer
- is any acceleration even available?

To answer your other issue with markers and performance - have you
looked at a custom lightweight marker instead of the official marker?

Martin.
