I am not sure of other peoples experiences. The visualization system I am
running based on OSG is very smooth on the Qt 4.1.4 version but when I
upgraded to 4.2 and without changing a line of code and just do a re-compile
the scene became very Jerky. Playing with Qt's timer interval it became
better but never looked into it further.
Not sure if this information is useful but I am also curious if others have
experienced similar problems.
I haven't seen this, but it sounds like the timer has been given a
lower priority or simply implemented differently.
Using GUI timers to drive redraws isn't ideal, for solid framerates
you really need to run a separate graphics thread. For any serious
vis-sim work this is essential. For interactive apps GUI timers will
often suffice, but as you've found out you are at the mercy of the
Windowing toolkits implementation of its timers.
