First up - LOVELY job Alexandre and team. The new UI is well thought through and performance generally excellent. No crashes so far on some quite complex HDR material. New projections and their respective parameter controls a significant new value.
The biggest new feature is of course the integrated preview with the new UI. There is a minor useability problem for me. When you adjust a projection parameter, for instance, the UI locks you out until the preview is re-rendered. This is not a problem per se - but the re-render starts very fast after a single parameter change. This means if you want to move a slider a decent way, you have to make 2-3 attempts, since the re-render kicks in before you have finished adjusting the parameter. Simple timing fix I would have thought. Would significantly improve productivity; right now the user is continually stalled.
I can not adjust the verticals on a cylindrical projection; the option is just greyed out.
I am looking forward to exploring the masking capabilities. It's something that I found time consuming in the past, in having to set up alpha masks in source material to achieve this effect. Most of my raw pano material now avoids this problem through timing of shots; but it will make me more adventurous.
Finally, I note some comments in the forum about GPU performance and perhaps needing higher performance hardware. In monitoring my GPU loading during editing, I note the GPU loading barely reaches 5%. Only a few of the cores seem to be active based on the monitor I use, and those only lightly loaded. The re-renders are not spectacularly fast but certainly very useable. My GTX570 has 1GB of RAM most of which is used by APG. I wonder whether there is a bottleneck in the GPU/CPU data transfer area; I have certainly found this to be the case in other graphics applications that leverage CUDA. (Overall my system plays nicely with AGP3 so I am not actually complaining here - just wondering whether there is some performance upside available... System is W7 x64, 32GB of 2100Mhz DDR3 and a water cooled 6 core i7 overclocked to 4.2GHz - supported by current generation SATAIII SSD's; very stable effective)
cheers and thanks for the new contribution to the pano world!
cheers

Yes, perhaps, we'll update the UI only when the slider is dropped. But I don't like this option either.

Normal. Verticals only exists in some projection : spherical and planar.

Good points. We still have to make ourselve a good benchmark of what is taking time in GPU rendering code.
