Title: GPU accelerator QML on TinyCore 5.2
Post by: imaad 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...

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

what is better for graphic display the default TC or Xorg?
I tried both and  no difference. Or concerning the video it's not difference between the two.

Deafault is Xorg.
