Hey Adam,
I am also working on a canvas game. I was in the same situation. Poor
FPS and such, so here's how I did it.
One of my test phones is a S3 Mini as well. In reality this is a very
poor device,
but I managed to get up to 50 FPS using Crosswalk, compared to just 10
FPS with a normal build.
What I did was re-program my game to use CreateJS/EaselJS libraries, see
www.createjs.com
It is a great set of libraries to easily create canvas games,
animations, tweens and other stuff.
And better yet, they have recently added WebGL support.
See: http://blog.createjs.com/webgl-support-easeljs/
Try runing this on your phone, and see what difference WebGL makes.
2D: http://createjs.com/Demos/EaselJS/bunnymarkEasel/?c2d=1
WebGL: http://createjs.com/Demos/EaselJS/bunnymarkEasel/?c2d=0
The next step would be to build your CreateJS WebGL-powered app with
Crosswalk 6 (which supports WebGL for blacklisted phones).
By the way, the S3 Mini is on the GPU blacklist, so you'll have to build
the APK with the following command.
Otherwise, it will still not use WebGL.
python make_apk.py --manifest=/game/manifest.json
--xwalk-command-line='--ignore-gpu-blacklist'
Right now I am trying to figure out how to get the Crosswalk 6 version
(instead of just 5) to work with Cordova so that we can use
their API's and the awesomeness of Crosswalk WebGL on blacklisted phones
(i.e; many Samsung devices).
In my experience, HTML5 apps would then be very very close to native apps.
Hope it helps.

Hello.
I'm trying to create a Canvas game for android system. Right now I'm
using
the Canary version (7) of Crosswalk to build .apk file.
The game runs pretty nice on new devices (like Nexus 4) but I have a
problem with older (like Xperia J or Samsung Galaxy S3 mini) where I have
about 10-15 fps (checked on Chrome browser, game as .html file).
When I use Crosswalk the animation is much slower (about 5fps less) than
when I use CocoonJS with WebView+ (
http://support.ludei.com/hc/en-us/articles/201849276-Webview-introduction
). CocoonJS generate much smoother animation.
I know that I will probably never achieve 60 or even 30 fps, but is it
possible to get CocoonJS performance?
I was thinking for example about the Chromium command line, but I don't
know what should be enabled or disabled to get better canvas performance.
Any ideas? Or it's impossible?
Thank you.
