We have an AMD Radeon R7 200 series video card, and we are still experiencing 2-3 second delays between songs, and a similar pause when trying to edit presentations. (This problem did not exist in 2009.)

I also noticed - I think others have commented on this - that the logo scaling isn't working. You can set it to whatever you want, but it's going to stretch the logo regardless! Not a big issue for us but, weird.

Had same issue until I reconverted database. Now runs with no delays!
