You are right. I don't know what I was thinking. Of course it will run quicker with a smaller canvas. Doh!
My baby son has my head a bit frazzled at the moment due to lack of sleep...
Anyway, I tried fiddling with hog2 after looking at hand of greed. Adding these seems to work really well on my iphone:
<meta name="viewport" content="initial-scale=1.0; maximum-scale=1.0; minimum-scale=1.0; user-scalable=0;"/>
<meta name="apple-mobile-web-app-capable" content="yes" />
<meta name="apple-mobile-web-app-status-bar-style" content="black-translucent" />
Edit: Obviously you cant zoom in or out but it definitely works better for an app. The address bar doesn't disappear like it should though....
I will work it out.
The fps shot up to 15 when I rotated it. It seems to like it.
I can't wait to install IOS5
