Solved

WebGL

We're launching a new viewer update tomorrow which will include a quality settings option. We hope this will improve the situation for low-end machines. It has been in development since the first issues were reported.

Of course, we can't make any guarantees that it will solve all the problems, as some seem unrelated to resources, and more to do with quirks in certain graphics cards or browsers. We have some other things we can try like a desktop version of the viewer which can run without the limitations of the browser and WebGL.

Re-engineering the game as we have gives us a lot more flexibility. Before, with Java, our options were very limited.

When the app comes out, it will be a native application in the Google Play and iOS App Store. It will not use WebGL at all, it will run on the devices hardware directly and make full use of it. It should run well on most phones and tablets. The old demo ran well on my Samsung S3.

I'd say that's probably not enough RAM.

We do have the possibility of releasing a desktop viewer, but with such a small team I'm concerned that it could throw up bugs of its own and become a serious distraction from developing the game. We really need to see if there's enough demand for it, or cases like this.
