Ok so I'm just starting a new project and thought hey, I'm not too far into it lets change it to use the new graphics 2.0.
There weren't many changes and I did it step by step to make sure I got everything working as was with v1, the main changes were the reference points and changed them to anchor points.
All went well and it worked well on my new iPhone 5S and iPad Mini (both running 7.02) so I thought lets load it up on my iPad 3 (running 7.02) since I have retina graphics, looks good except there is a definite lag when I am dragging things around the screen and the transitions were slow or skipping.
I thought maybe I missed something, so I undid the changes one by one and tried each version on my iPad 3, it only became smooth when I didn't use graphics 2.0.
I'd like to upload the files but there are a quite a few and I don't really have time to make a demo project but I thought I would bring it to the attention of the masses and the management, to see if anybody else sees the same problem.
