Very Slow dialer

hey guys
T_ don't know why but the dialer on my note2 is very Slow and UnsatisfIng.
I tried using other rom rather than the Stock and now I'm using Omega but still it takes him about 4 sec to open dialer/Contacts and the Scroll is laggy.
how Can I fix this problem without dl another dialer?

Try dialer+ in the play store I think that's a great dialer

Do you have a boatload of contacts with photo ID's?

If so that sadly is probably whats happening here.
