Tegra ideas

The issue is that often times, the fastest way to do something is the worst way to do something on iOS hardware (PowerVR SGX), e.g. clears are very cheap on iOS, but very expensive.

See #77 for list of tasks.

Interesting. 👍

in terms of nv path I noticed https://github.com/ake-koomsin/mapnik_nvpr. Not sure if it has anything interesting however (not looked at code).

We're getting much better performance when avoiding to clear all the time. There are still a few rendering artifacts which occur with Tegra, but not on desktop.

We should probably render in "retina" mode. That means that everything is a little bigger on the map and we have fewer tiles to render. This is also in line with reports of too tiny text on the maps.
