drivers - Slow/laggy system on a mid-end PC

I just moved from Windows 8.1 3 days ago (which was running very good in terms of performance and multi-tasking).



I'm using Ubuntu 15.04 with KDE Plasma 5.3 installed and the system isn't fast as it should be.



My specs are:




Gigabyte G41MT-S2P



Intel Core2Duo E7500 2.93GHZ



AMD 5570 1GB DDR3



4GB Kingstone RAM



It lags when I've simple things opened like Chrome and VLC.




eg: hovering over "Leave" in the application launcher takes ~2 seconds to show the Log off, shutdown, and other options. and Dolphin lags every now and then..Some pop-up messages take time to load.



the thing is: when I take a look at KSysGuard it shows only ~20% of the CPU and ~2.5 GB of memory is used (and ~no swap used)..What the heck is wrong?



I heard that it might be a problem with the AMD driver, but I'm using the prosperity one from "Additional Drivers" on Ubuntu.
