Hello Jann,
I am using RB2009 Pro to build a front end for an ECG display (real
time). I find that on Windows XP running on a C2D 2GHz with 512MB RAM
and motherboard graphics that my app draws with notably reduced
speed. The difference is considerable - on my OSX.5.7 MBP 2.4GHz
with a 256MB GeForce 8600M GT - the screen write is very snappy.
Filling a list box is also a slow horse on Windows.
Regards,
Tony Barry

I was talking to someone at REAL last week and they indicated that
the Windows version of the compiled apps suffer from drawing issues
due to the drawing method they employ in the compiled client (not
IDE) interface.
I am seeing that on some windows computers of the same CPU speed and
ram amount (with the only difference being graphics card type) are
displaying a lot faster and smoother then their brethren that have
lower end graphics cards.
I am seeing this specifically in the following:
My app uses tabpanels with listboxes and editfields on each tab.
When switching between the tabs on windows you see the HUGE lag in
drawing time. On OS X this is nonexistent (Leopard). On Linux it is
also nonexistent (Umbutu). On windows machines with better graphics
cards the lag is less huge...but on windows with generic graphics
cards (or built-in graphics chips) this redraw is massively bad --
sometimes taking 5 -10 seconds to complete drawing of 3 listboxes
and 5 editboxes with some statictext fields tossed in for labeling.
The engineer at REAL indicated that this, as i said, is due to the
"older" drawing method RealBasic uses to draw on windows. My
question is this: are others seeing this lag? also: What method
does RealBasic use that is so laggy and how come this has not
changed. My platform is WinXP for the clients.
I am seeing other cross-platform apps that use things like QT (to
draw the screen) are not suffering from this -- wondering why REAL
is so behind the times on this.
TIA
Jann
