GPU accelerator QML on TinyCore 5.2
« on: April 29, 2014, 03:56:44 AM »
Hi,

I install Qt5 on TinyCore and I made a little application in QML with a short animation. The application run but the problem it is that the application is very slow, moreover even if I don't use animation an I try just to replace an image with another image it take too long time (about 32s) to change the image.
Does anyone have an idea why?
It's a video driver problem?
Do I need to install an extension?

Thank,

Just for info.
I test the same QML application on raspbian an it's work very fast, and even if I change image quickly the CPU is 0.4 % use.
When I try the same think on Tiny Core the image change in about 32s and the CPU is at 98%, if I stop to change image the CPU is 0.4%.
So I think a video driver is missing or something like that...
Any idea...
Best regards,

In piCore there are no hw accelerated graphics. No idea how Raspbian Qt5 built.

Deafault is Xorg.
