Query in 40000 chip demo

@ Jacek
yes i tried rebuilding the application, using each loop

@wysota,
thx, even i guessed that it is in middle, in fact the aim of writing the new loop was to see how zoom would be affected if the middle is changed to top left

So I would like to know how changing the middle cordinate of the scenen si affecting the speed of dragging ??

Any help ?

@jacek... sorry didnt annwer u completely..
well the original version runs fine when i restore to it.
And ia m not using any optimization,,,using the defaults when i open the project in Visual Studio.
The problem is occuring when i change the loop , making the middle cordinates as top left.

Do I understand you correctly, that if you change that loop back to original version and recompile the example, it works faster?

@wysota even i want to know why was it affetcing the speed while dragging the chips..
u can try urself...

@jacek u r right... the original works fine,,, but whne i change it, the dragging becomes slow .. i amnot able to logically make out why is it happening

It works fine for me... I don't experience any slowdowns.

For me too. I have both versions running side by side and I don't see any difference.

Something else must have been changed in the code.

@aamer4yu: Could you make a diff of the source code to see if there are any other differences outside the loop?
