[SDL] Performance questions from a MacOS X user

(well, actually from a Visual C 6 user who is trying to appreciate the
Mac world :-)
I' delighted to say that I got the SDL samples compiled under XCode3
(leopard). Apparently, dropping the given FrameWorks for SDL projects
into /Library/Application Support/.Apple/Developer Tools/Project
Templates/Application/ doesnt work under leopard : after quitting &
restarting XCode, these new types do not show up in the wizard of "new
project".
fortunately, one can simply these frameworks as a whole, fiddle around
a bit to replace the template strings, and get things compiled !
What worries me though is the gdb console output that I see when I run
the application :
2007-11-09 23:33:19.573 «PROJECTNAME»[2332:813] Warning once: This
application, or a library it uses, is using NSQuickDrawView, which has
been deprecated. Apps should cease use of QuickDraw and move to Quartz.
What does this imply ? Will this have a performance hit on blitting 2D
sprites ? My application is very very simple (just some 2D surface
blitting) but really really really needs all the speed it can get,
since it will be used for psychology priming experiments on 200Hz
monitors, so I really have to be sure that I can blit a few sprites in
less than 1millisecond.
is there any way to reassure myself that blitting is hardware-
optimized within VRAM ?
many thanks !
