Qt designer is too slow
I'm using Qt 5.0.1 and when start Qt designer it becomes too slow, (I have I3 2.27 GO, ATI Raedon 2GO, 4Go Ram) when i insert a button or something in the window i need to wait like 3 seconds and one of the cores of my CPU goes to 80% to 90% at that moment
I hope it should work faster. Remove all Qt installed files and try to install Qt again. Also Qt by default installed in C drive where the OS and all program files exists. Make your C drive faster by installing most of the programs in another drives like D, E etc. Also disable the startup programs in your OS. check msconfig in windows.
