Difference: LcdFrameRate (r49 vs. r48)

Rockbox LCD Driver Frame Rate

test_fps

The plugin we use to measure an LCD's FPS. It is not built by default, so you need to add it (test_fps.c) to your apps/plugins/SOURCES file and rebuild in order to use it.

The boost counter needs to be manually changed to see the different CPU frequencies.
