sorry for my bad English.
I installed AE on my new PC, its specs:
Intel i7 4710HQ.
1TB HDD, 8GB SSHD.
Windows 8.1 64 bit.
when I copy any object and paste it, takes about 1sec to 3sec. and when moving anything in my project it looks very slow.
I tired to update to latest version and reinstall AE but nothing change.
