Subject: mas_disable_remote_layer.patch
|
|
|
|
Disable remote layer APIs (CAContext and CALayerHost) for MAS build.
|
|
|
|
Accordin to ccameron:
|
|
|
|
For apps that spend a lot of time watching video (especially fullscreen video),
|
|
the power/battery usage will likely increase 1.5x to 2x. For something that is,
|
|
e.g, scrolling, it'll be smaller, more like 1.15x or 1.25x.
|
|
|
|
In terms of performance, the impact will likely be fairly small -- any app that
|
|
could hit 60fps before will likely still be able to hit 60fps. There may even be
|
|
cases where performance improves when disabling remote CoreAnimation (remote
|
|
CoreAnimation is really only about battery usage).
