More results: This BlitzPlus code:
Open in online IDE
Graphics 800,600,32,1

Local s =100

Local x=0-s
Local y = 300
Local Sync =1

While Not KeyHit(1)
	Cls
	Rect x,y,s,s
	Text 0,0,"Flip "+Sync
	Flip Sync
	
	x=x+5
	If x > 800 Then x = 0-s
	
	If  KeyHit(57) Then
		Sync = Not sync
	EndIf

is smooth on my PC but not on the laptop. However if I change the last Graphics flag to 2 (for windowed mode) it is smooth.

BUT if I change the BlitzMax code sample to run in windowed mode: i.e. Graphics 800,600,0,60 It's still jerky. If I remove the 60Hz off then end: Graphics 800,600,0 it's still jerky. And finally if I do this in BlitzMax:

Local DesktopRefreshRate = GetDeviceCaps(GetDC(0),VREFRESH)
Graphics 800,600,0,DesktopRefreshRate


It' STILL jerky. What gives?
