I doubt that. I have experienced this on all 3 laptops I have owned since Cinnamon, and my current Lenovo X1 Carbon lightning made me realize it's not me, it's Cinnamon.
Did a search and I am not the only one.

Although I am GUESSING GNOME_Shell menu has exactly the same problem, since it's a fork and all..
Let me rephrase that. I hope you are right. A fix by configuring would be awesome. Fades and other graphics like expo and desktop-chooser go lightning fast. I can play Doom3 just fine. The only thing that is slow in my whole UX is the time between commanding the menu to open, and it actually opening. It's not a lagging fade, because the delay varies between instant and 5 seconds, with an average of 1 second.
Any thoughts on where to look for this misconfiguration? I haven't got any restricted or additional drivers installed. I have an i5-3427U processor with Intel HD 4000 graphics. My previous two laptops with similar issues were Intel Core i3 and Intel Pentium M.
Are you sure your menu is instant? Press win and directly start typing. Is it all captured by the menu inputbox?
