Hi everyone! I'm using vmware workstation 12.1 pro on my computer (i7 6700k 4GHz, 16gb RAM, nvidia 970) with Windows 10 pro latest build. (10.0.10586.71) 64bit as host OS. When I try running Win 7 pro 64bit in a vm and enable Aero effects, dragging or minimizing windows becomes very slow and lags. With default windows 7 basic theme all works fine. I think it's not a lack of resources, infact windows 7 guest performance index is 7 over 7.9. It looks strange because on my old macbook pro using vmware fusion 8 pro that is A LOT less powerful it runs smoot as a charm! Thanks in advance!
