RPi Touchscreen and framerate

Sat Sep 12, 2015 8:13 am

Is there a limit to the framerate on this display with its current driver? I can't get consistent 60fps at 800x480, tested with mame4all and pisnes using dispmanx/GLES and its triple buffering. It hovers around 55fps.
No problems with consistent 60fps on a normal HDMI display.

Update Press F9 in mame4all to switch off autoskip and it runs smooth at 50fps although game runs slower.

The display looks to be locked at 50fps whatever HDMI settings I use.

Here's the official response from Gordon Hollingworth:
"Due to limitations in the design of the bridge 50 is about as close as I could get, but I didn’t try very hard… Will have a look again to see if we can do better"
