Hi,
I have a Thinkpad with Intel GMA 4500HD grafics card and just wonder why effects are not as smooth as I would expect.
No no - I don't only talk about that eye candy things that may require some powerful GPU (although I think that even the GMA should be able to handle this nowadays) I mean even dragging windows when KDE desktop effects are disabled.
Moving windows is not smooth, meaning there could be more screen updates to make movements look fluently.
I'm talking about normal movements which for example look very smooth on a Mac.
Glxgears gives me about 2.000-2.500 fps, so I assume that the grafics driver works well.
CPU usage is also low when moving windows.
I tried to take a look into the xorg.conf to maybe tweak it but there is none since 9.10 and the system configures X automatically.
So, the question is: if we assume the GMA chip is fast enough to do more and the CPU usage is low (and it's not a weak one) - why is the movement not perfectly fluent?
(this is no vsynch tearing issue - it's about the number of redrawings per second)
Any idea? Anyone with similar issues?
