Ok i tried almost everything ... (hardware and sound acceleration etc.)
It seems the delay is gone .. BUT now the lyrics dont show and i only see a flickering of colors
I have two computers , so i installed the khpro on my second system to check and it has the same problem (color flickering instead of seeing the words filled )
The program works great , so it isnt the khpro that causes a problem ..
I did the DXDIAG test on my 2 systems
So in this post will be the test of my main pc (the on i am using now )
