You know I've been reading these days all the threads about rMBP since I plan to buy one, today I went to the Apple Store and played with two 15" 2.3 8G rMBP's, I opened 5 spaces, in one space I had iTunes playing with the 3D effect visualizer, in another space had safari playing a HD video, and on the others spaces I had apps such as Pages/Logic/Calendar opened but they were not accessing 3D, guess what?, the rMBP had hard time when swapping among spaces, the 3D iTunes effect was slow and the video from YouTube was stuttering, even typing was extremely lagging while having all these apps running at the same time, dragging a window or scrolling was slow, and the CPU Monitor reported very low usage on every 8 CPU instances, so CPU speed was not determinant in this test, I made this test on 2 rMBP's to rule out a defective machine, this test was done on the recommended retina resolution, I have never experienced this kind of lag on my old early 2010 iMac, even running 2 difference virtual machines Windows/Linux at the same time in difference spaces.
I also made a test loading safari with web pages containing lot of pictures and graphics elements and I was able to see a kind of lag in some of them, specially those with hi resolution pictures.
I know I had the impression this was software issue but this tests make me think, it seems that rMBP is really pushing the limits of its GPU, and now I don't know what to do whether to buy now or wait for a refresh.
What do you rMBP owners think?
