Dear All, I have a simple scene with some (non-transparent) cubes: [ScreenShot2016-03-04at14.27.04.png] While this motion was relatively fluent (10-20 fps I estimate) in version 10.1, 10.2, 10.3., 10.3.1, it is roughly 0.3 fps for me in version 10.4. Can someone else confirm this behavior? I’ve …

Also cool: On the higher MacbookPro Retina (Mid2014, 3GHz i7,16GB, Intel Iris 1536 MB) this rotates substantially worse than on the MacBooPro (Mid 2012, 2.9Ghz i7, 8GB, Intel HD Graphics 4000 1536 MB). M.

So you’re saying less is more… hmmm I btw have the mid 2012 macbook pro retina (the very first retina notebook that came out).

Yes, I have noticed that on several occasions. It is occasionally very difficult for me to predict on which machine (including MacPros and iMacs and even Linux Clusters) Mathematica is faster; the specs do not seem to be very predictive. I also work for a company on a Windows server (no way around i…

I’ve never seen any negative correlation between pc speed and performance yet, so very interesting that this can happen!

There is an edge/line drawing bug found which only happens on Retina (Mac) machines. It might cause 4 or 5 times slowness for some examples. We are expecting to have a fix soon.

Hi Yuzhu Lu, great to hear you tracked down the issue! Is it also related to this line-drawing bug (from here ) [ScreenShot2016-03-05at13.22.33.png] or is this simply z-fighting?

This might be caused by a depth offset made to edge/line by default so that it will not look dashed on a surface (avoid possible z fighting). You can try to turn it off with a method option: Graphics3D[..., Method -> {"EdgeDepthOffset" -> False}]

I’d like to see the pre-release program come back. I also have this particular problem, (Retina MacBook Pro with dedicated graphics.) I set the option to auto-switch, but I think that the computer always uses the dedicated graphics with Mathematica. I re-installed 10.3.1 until this issue is resolv…

Thanks I didn’t know about this option!

I tried to turn it off, but with no success (I got exactly the same as without the option specification): [2016-03-20_22-45-19.gif] Is there anything else we can try? (10.4)
