  — - have you tested WebGL shaders on a device with a Snapdragon 800 or newer? They should have decent performance. Something as old as the iPhone 4S on the other hand will struggle.

  You need letterbox integer scale, point sampling and pixel rounding for perfect seamless rendering.

  The Tilemap object can be hundreds of times more efficient than having grids of sprites. See this blog post on some inner workings of tilemaps.

  eli0s - the correct fix is to set the X to Self.X + 856. If you set the X to 0 you ignore any overshoot. At 750px/sec it's jumping about 12 pixels per tick, so it could end up as far as X = -868. If you just set X to 0 it will visually appear to jump by 12 pixels, but if you move it back by its own width it takes those extra 12 pixels in to account and remains smoother. With that applied it seems perfectly smooth.

  It might be best to ask Amazon, especially if you can't see the problem on your own device.

  — - WebGL shaders *are* GPU-accelerated, but mobile GPUs are just a lot weaker. 3D games render differently and can actually have considerably less overdraw than 2D games, making them faster in some cases. Some shaders are also slower than others (e.g. blur and water shader can be slow, but most blends are fast).

  — - what's the performance difference between canvas2d and webgl and can you share a .capx demonstrating that? Is it the same across iPhone models (4S, 5...) and iPad?

  Are you sure it's not just because mobile devices have small, tinny-sounding speakers? Hard to get a subwoofer in something the size of a smartphone.

  Have you read the manual entry?

  It should work on all platforms. I think the name misleads people, perhaps it should have been called "Local storage".

  Anything not in the 'Performance tips' article is generally not important to performance.

  So this does not affect any other browsers or platforms? I will look in to this but it may be that it's a problem in WP8.1 itself, since our engine is nearly identical on all platforms, so if the problem was in our engine it ought to show up on other platforms.

  Closing, looks like accidental report.

  Node-webkit is due a new version to bring it up to date with Chrome 34. Let's wait until that's released and see if it's affected. Perhaps it's a problem with the 0.9x branch alone.

  The C2 engine would not do this, so it sounds like a mistake on your part. Hard to say what it could be without more information.
