A regular window.

But I see this a problem only on an old computer, on a new new one faster I see no difference between CEF<>Chrome, but it probably depends what kind of stuff you have on that webpage, so best to test it yourself.

I've tested Berkelium (bin/Berkelium.exe) on that Atlhon 1800.
Its scrolling is not slow, it has a slow speed of mouse wheel scrolling - seems like not using the system's setting, that's why it feels slow.
I've tested scrolling by dragging the scrollbar and the difference between Berkelium<>Chrome is minimal (20% percent I would say in favor of Chrome).

I don't know what is that "bin/glut_input.exe", but it is running very very slow (the scrolling is x4-x8 times slower than in Chrome).

NPAPI support is problematic on Mac. See the below resources for more information:

Some background information:

Google's semi-official line is that they prefer people to use PPAPI (http://code.google.com/p/ppapi/) or NativeClient (http://code.google.com/p/nativeclient/) for developing Chromium plugins. One problem with PPAPI is that it's currently only supported by Chromium. It CEF is going to support a Chromium-only plugin API then it may make more sense to expose WebKit's WebPlugin interface directly (http://trac.webkit.org/browser/trunk/So ... ebPlugin.h). The WebPlugin approach would make it very easy to implement native windowless widgets but more complex to implement native windowed widgets. So CEF will probably keep NPAPI as the cross-browser/windowed plugin option and support WebPlugin as the wiz-bang snazzy embedded windowless widget option.

Thanks for the info.

It seems like Windowless + opaque would be what I'd need in order to overlay the UI onto the plugin.

Well I'll mess about with NPAPI on Windows at least and get an idea of whether the theory and performance stands up anyway.

CEF looks like a cool framework anyway.
