Hi Marco, thanks for testing it!

That's expected right now and it's good in fact that there isn't any regression. I haven't had a chance yet to finish the work on speed improvements by making use of lots of available VRAM, there is some of the infrastructure in place for it but that's something that I will be working on more once things stabilize. Please remember this is only the first beta and does not contain everything that I want to have in the final v4 release in it as of yet.


> B) It seems that V4 has the same issue of displaying "fake edges" in some part of the models

That's expected, it should behave exactly the same as V3 right now.


> C) As you can see in my video, the antialiasing of edges and above all of surfaces's boundaries is unsatisfactory.

Same thing here, it's expected to behave the same as MoI v3 at this moment. But it will not be difficult for me to add in an option to enable MSAA once the initial stabilization is done.
