I am running qnx 6.2.1 for just a few days and I noticed that while moving a window a high cpu-load is caused and visually you can see this, too, because the moved window won’t redrawn instantly.
The same problem exists with FireFox: if I start to scroll down a webpage, the cpu-load is going to be 100%.
If I stop moving a window the cpu-load is going to be normal.
But if the cpu-load is very high, sounds played by any player are distorted.
I think it can be my graphics-adapter, but I’m not sure, because I don’t know how QNX 6.2.1 works inside and I don’t know what can cause such a “lag”.
After some minutes this “lag” is going to be bigger. The normal cpu-load is raising to 30% without doing anything.
I think it’s time to tell you my hardware .
Processor: AMD Athlon K7 700 Mhz (Slot A)
Graphic: Elsa Erazor III Pro (TNT2)
Memory: ~392 MB // the system-information shows only 312, strange, eh?
Sound: on board (via chipset)
My computer has no special hardware, only one old isa-audio-card, but I don’t need this one.
In my first installation of QNX I encountered the same problem, but after some minutes this “lag” disappears, so it was ok, but now this “lag” increases minute by minute.
I can remember that the dialer-software has already caused a 100% cpu-load, but that was in another installation of QNX 6.1 (?) → I don’t know anymore.
If you are interested in my problem and if you are willing to help me than I would be very happy .
For more details of my system I have uploaded the sysinfo, which is generated from the system-information-software of QNX.
Sincerely, Andreas Schipplock.
