How do you want to do that? I'd like to use it in my game, but haven't found solution.

In my case, there's no difference. Both devices are blacklisted and switch to canvas 2d.

@TiAm
Webgl version of my game failed on S3 mini, it shows Canvas 2d instead.

@Knifegrinder - it is not. I will have a build up later that skips the blacklist

* Webgl version of Propaganda game http://egyptoon.net/games/prop2/index.html
Renderer= Webgl (now it's active)
fps= 30 (crosswalk 7 is better by 10 to 15 frames per second)
cpu load = 50 to 60 %
huge improvement in performance but Crosswalk 7 is still better
-------------------------------------------
* Canvas version of Propaganda game http://egyptoon.net/games/prop/index.html
Renderer= Canvas 2d
fps= 41 (very close to Crosswalk 7, may be the same performance or less by 5 frames!)
cpu load = 50 to 60 %
huge improvement in performance! ALMOST the same performance of Crosswalk 7, YES! i need this version please! I'm very happy with it!
THANKS for your great work!

@Egyptoon - just wanted to clarify. The build I posted with the --xwalk-command-line="--ignore-gpu-blacklist" has acceptable performance?

Anyone else with feedback?

@imaffett
YES, this is it ( --xwalk-command-line="--ignore-gpu-blacklist")
https://www.dropbox.com/s/1y65f1hnh64o1 ... m.apk?dl=0
this command line makes the performance = Crosswalk 7 performance, almost the same, very acceptable.

@Egyptoon - Thanks for the verification. I hope to have more news next week (the Crosswalk team is out of the office now for the weekend).

@imaffett

Yes, the performance is much better with gpu blacklist off.

Samsung Galaxy Tab 3 SM-T110 - Android 4.4.2
Skia gpu on - fps 3-12
Skia gpu off - fps 28

GIGABYTE GSmart Guru G1 - Android 4.2.1
Skia gpu on - fps 5
Skia gpu off - fps 24-25

On both devices fps jumped up significantly and is stable without spikes.
