Here are some of the things I have noticed on v13:
- The 3D settings - as in the "depth" setting which really adjusts the zero parallax point by sliding the images horizontally does not work at all. It looks like it will increase the separation but not allow the other way. So now I have about a 20cm separation on my main screen (Panasonic AE8000 projector, 100" screen, Nvidia 650 ti card). I can't get it to go back. Even more weird is that you can't adjust it while the 3D is playing (even if it worked). The 3D menu for that setting only is available during 2D playback which if it did work would be frustrating.
- Turning on TrueTheater literally causes the projector to lose signal. It jumps back and forth and sometimes it picture is there and sometimes not.
I was carefully looking at a 2D bluray video and it looked horribly "grainy". It was like there was a high frequency noise or oversharpening effect being applied. Just horrible. The same bluray on v11 on the same computer seconds later was just fine.
- The "resume" function does not work. I noticed other people on the forum with this issue too.
So to me it looks like this v13 has been released way to early and is still in beta form.
