Hello all,

used as to work with 2014 with no problems.

since 2015 installed there are some problems: first of all it's very slow...

and I have a strong system with a quadro k2200 graphics card so it should have no problems. Even with the same file, compared on the same system to 2014 version (luckily I have them both installed) the 2015 moves, rotates, and does about everything very slow.

besides that, there is a strange problem of it not saving my preference. Each session I need to push the 3D graphics acceleration button, and the next time I open I have to do it again.

and another strange issue is that it always forget to open full screen, it's always a  floating window on my desktop.

by the way, all these issues have been through version SP0 to SP2 which I just installed.

its also an issue that I had with 2 different graphics cards, and even after a system reformatting and reinstalling had the same problems return.

hope you can help out,

thanks, joel​
