Did you report this bug?
Not yet, no. I need time to prepare some solid test cases.
RGBBitmap32 : 19ms / frame
but
for just slapping lines down on a canvas LazRGBGraphics is hard to beat.
I'd like to give it a try. 19ms does not sound that fast. Definitly missing the
magical 60fps. How many lines did you draw for this tests? And did you only
measure the time for drawing/rendering or the time for a whole frame update?
Uh, about 4000 lines, and the time was from "receive a packet of bytes" to after the
"application.processmessages" that ensured the display was properly rendered.
The pre-processing of the array was usually less than 1ms, so the rendering is what takes the time.
The drawing is pretty fast (usually ~1.5ms).
When I can only get 45fps from the Scope hardware, I'm really not fussed about not being able to
draw 60.
What is magical about 60fps?
Regards,
Brad
