How much does Win OS graphics card affect display speed?

[Jann Gobble <janngobble@gmail.com>]

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
